Abstract

Two local varieties of Gossypium arboreum, PM2 and PM3 were treated with colchicine solution for polyploidy induction. Two colchicine solutions, colchicine solution # 1 (0.1% colchicine) was derived from powder sold by Sigma and colchicine solution # 2 (0.5% colchicine) from drug tablets for gout treatment. Three experiments were undertaken which were, Experiment 1: apical meristem dropping with colchicine solution # 1; Experiment 2: seed treatment with colchicine solution # 2. Experiment 3 : apical meristem dropping with colchicine # 2. All were compared with the untreated (water treatment) controls. The results showed % germination of PM2 and PM3 after seed treatment to be lower than those of the controls. The same were found with their heights. Eleven, nine and three presumably polyploidy plants of PM2 in Experiment 1, PM3 in Experiment 1 and PM3 in Experiment 2 respectively were found to have stomata sizes of 24.9%, 34.9% and 31.4% increased and stomata frequencies of 24.2%, 46.5% and 45.9% decreased compared to those of the controls respectively.

Abstract

Protoplasts were isolated from callus, cotyledons, hypocotyls and leaves of cotton (Gossypium hirsutum L. var. Coker 310) using different digestion media. Protoplast yield per gram of fresh mass of leaves, callus cotyledons and hypocotyls was 22.2, 5.5, 1.7 and 1.1 million respectively. Protoplasts were most viable in basic medium in presence of thidiazuro 0.663 gm/l and 2, 4, 5-trichlorophenoxy acetic acid 7 mg/l. Hypocotyl and leaf-derived protoplasts formed microcolonies. Addition of CaCl2 and glutamine to the basic medium improved protoplast survival, and division of hypocotyl and leaf-derived protoplasts. The growth conditions, such as the light and carbon source of donor plant were the important factors for protoplast isolation and culture.

Abstract

Correlation and heritability estimates of the yield and the fiber or lint quality were determined using 15 F1 cotton hybrids obtained from a diallel cross made in the Werer Agricultural Research Center, in Ethiopia, in 2003. The results indicated that the seed cotton yield was highly genetically correlated to boll weight (r = 0.99**), lint yield (r = 0.88**) and lint index (r = 0.96**). The lint yield was highly correlated to lint percentage (r = 0.94**) and the number of seeds per boll (r = 0.96**). The results illustrated that a high lint percentage, more bolls per plant and a small seed size were positively correlated to high cotton lint yield. Fiber strength was highly correlated to all fiber quality parameters and positive correlations were found between staple length 2.5% (r = 0.99**) staple length 50% (r = 0.64**) and fiber strength. A positive correlation was also found between the fineness indicator (micronaire) and the uniformity ratio (r = 0.61**). However negative correlations were observed between fiber length and the fineness indicator (micronaire) (r = -0.86**), short fiber index (r = -0.85**) and uniformity ratio (r = -0.99**). Negative genetic correlation coefficients of lint percentage and lint yield with fiber strength were quite high (r = -0.99 and r = -0.96**, respectively), but they had a positive correlation with the fiber-fineness indicator or micronaire (r = 0.99** and 0.79**, respectively). The broad-sense heritability estimates of the yield and yield components were high for lint percentage (h2 = 97%), lint yield (h2 = 72%), lint index (h2 = 79%) and seed index (h2 = 86%). As they also had a strong relationship with other fiber quality parameters as well, they could be considered as indicators of the yield and fiber quality improvement in cotton.

Abstract

The effects of plant population density on diurnal changes of leaf orientation behavior and canopy structure of cotton (Gossypium hirsutum L.) during growing season were studied under field conditions by using an electromagnetic digitizing system for characterizing the canopy structure. At high density (80x9 cm-138,890 plants/ha), leaf area index (LAI) developed more rapidly than medium density (80x18 cm-69,440 plants/ha) and low density (80x40 cm-31,250 plants/ha), respectively, due to a greater number of leaves per plant. At the same plant age, plant characteristics, except leaf area plant and leaf area expansion rate (LAER), of high-density canopy differed from medium-density canopy while those expect leaf size differed from low-density canopy. Medium–density canopy did not show significant difference of plant characteristics compared to the low-density canopy, except leaf size and number of leaves per m2. At the same LAI stage, the cotton plants under high density had different plant characteristics, except leaf size and number of leaves per m2, from those under medium density. However, the plant characteristics, except internode length and number of leaves per m2, of high – and medium- density canopies did not differ significantly from low-density canopy. Leaf orientation behavior did not differ significantly between plant densities, particularly at the same stage of LAI. Cotton leaves tended to face the sun more at noon than in the morning and in the afternoon during growing season. Changes in horizontal and vertical distributions of leaf area were not significantly altered during the day by diurnal leaf orientation, but they differed significantly during growing season. These changes were significantly different between the three plant population densities at the same plant age. However, there were no significant differences in horizontal and vertical leaf area distribution at the same stage of LAI among the three plant population densities. This quantitative description of canopy structure may be useful for developing mathematical models of light interception in the canopy of cotton.

Abstract

Subtending leaf has been known to be a major source of photosynthate for the attached boll, but little is known about quantitative relationship between actual variability of subtending leaf irradiance and boll production and fiber quality. The objective of this study was to quantify this relationship by using low-cost photoelectric sensor mounted on subtending leaf surface for leaf irradiance measurement during 4 different periods of boll development, i.e. from squaring to 5 days after anthesis (DAA), from anthesis to 25 DAA (fiber elongation period), from 15 to 45 DAA (fiber thickening period), and from squaring to 45 DAA (Whole reproductive period), and the Advanced Fiber Information System (AFIS) for fiber quality analysis. There were large variabilities of boll and boll component production, but less for fiber quality parameters, except short fiber content (SFC). Photosynthetically active radiation (PAR) captured by subtending leaves showed a substantial variation for each period of boll development whereas cumulative degree day (DD) was less variable. Variability of light captured by subtending leaf (LCS) was positively correlated with subtending leaf size. Increase in LCS during squaring -5 DAA resulted significantly in increased number of seeds and fibers per boll. During reproductive period (i.e. from squaring to 45 DAA). Increasing LCS could increase significantly dry matter of the boll, seed cotton, carpel, delinted seed, and fiber. However, variability of LCS during fiber elongation period did not affect significantly fiber length (both mean length, L, and SFC). Fiber linear mass (FIN), were not significantly affected by variability of LCS during 15-45 DAA. In this study the DD during determining periods of boll-component development did not show significant influence on boll production and fiber quality. By hypothesizing that assimilates photosynthesized and stored in plant parts before the determining periods might also be used for fiber growth and development, fiber length (both L and SFC) showed a significant correlation with cumulative DD during squaring -25 DAA while fiber maturity and fineness (FIN) was significantly correlated with cumulative LCS during anthesis-45 DAA. Increasing light interception in the canopy may improve boll production and fiber quality of cotton Quantitative relationship between subtending leaf irradiance and boll and fiber characteristics may be useful for developing predictive models of boll production and fiber quality in relation to light interception of cotton.

Abstract

Due to the difficulty of producing F1 hybrid seed, the use of heterosis in cotton (Gossypium hirsutum L.) has been limited. This study was conducted on fifteen F1, fifteen F2 and 6 parental genotypes obtained from partial diallel cross of 6 varieties with the objectives of comparing the parents, F1 and F2 generations and to identify the competitive potential of F2 hybrids over the best yielding cultivars for yield component and fiber quality parameters. It was evident to find the seedcotton and lint yield superiority of F1 hybrid over parents and F2 generations. F1 hybrids showed an overall seedcotton yield advantage of F1 over the parental means of 26.4 %, while F2 hybrids were 9.3%. Best F1 hybrids showed 19.5% yield advantage over the best check parent, while best F2 hybrids were only 2.5%. Almost the same pattern was observed for lint yield with the level of heterosis at 28.6, 10.2, 30.4 and 0.8 % for F1 and F2 mid-parent and best parent, respectively. Significant differences were not observed for fiber quality parameters except fiber strength. The result of this study demonstrated the potential of F1 rather than F2 hybrids and the need for further investigation on heterosis and inbreeding depression and development of economically feasible hybrid seed production technology.

Abstract

Heterosis and combining ability for yield and yield components were determined in a population derived from half diallel crossing of six cotton genotypes. Heterosis and heterobeltiosis occurred in varying degrees. The highest heterosis for lint yield was 66.4 % and for seedcotton yield was 46.3 %. Five of fifteen crosses showed significant heterobeltiosis for seedcotton yield. Significant heterobeltiosis was predicted for crosses of GL-7 X Cucurova1518 and Del Cerro X Cucurova1518 for seedcotton yield, which resulted in 19.5 and 19.0 %, respectively. The analysis of variance to compare between parents and F1 crosses showed that the mean squares of genotypes and general combining ability (GCA) were significant (P<0.01) for all traits studied. However, the mean square of specific combining ability (SCA) was significant only for lint percentage and seed index. The magnitude of GCA was higher than SCA in all cases, indicating that additive gene action was more important than non-additive in the inheritance of the traits. In this study, Cucurova 1518 and GL-7 were good combiners for yield and yield components. The two best crosses for seedcotton yield were GL-7 X Cucurova1518 and Del Cerro X Cucurova1518. Best parents and best crosses could be used to develop high yield breeding materials.

Abstract

The effects of Mepiquat chloride (Pix) on the performances of 58 cotton plots were studied during 1994 and 1995 at Chaibadan district, Lop Buri Province. Pix application at early blooming reduced significantly vegetative growth (node production, inter-node length) during the reproductive period and shortened the crop duration. Over all plots the average seed-cotton yield was not improved by Pix despite significant changes in boll distribution pattern and boll-size. Large variation in yield response existed between plots. The response depended on the rate of increase in internode length prior to Pix application together with fruit retention of the first fruiting branches.
