 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Breeding of Soybean (Glycine max (L.) Merrill) for Field Weathering Resistance by Pedigree Method) ผู้เขียน:Phan THI THANH, ดร.ประภา ศรีพิจิตต์, รองศาสตราจารย์ , ดร.วาสนา วงษ์ใหญ่, รองศาสตราจารย์, นางสุนันทา จันทกูล, ผู้ช่วยศาสตราจารย์, Arom Sripichitt สื่อสิ่งพิมพ์:pdf AbstractBreeding of soybean for field weathering resistance was conducted by hybridization between commercial variety CM60 which is susceptible to field weathering and two field weathering resistant varieties (GC2796 and SJ1) in 2003. The F1 hybrid plants were grown in the greenhouse at the Department of Agronomy, Kasetsart University and the F2 to F4 progenies were planted in the field at National Corn and Sorghum Research Center, Nakhon Ratchasima province. Field weathering resistance of soybean was evaluated from some seed characteristics involving seed germinability after accelerated aging, seed vigor estimated from the electrical conductivity of seed leachates, percentage of seed coat and seed coat thickness. Selection was done in each succeeding generation from F2 to F4 using pedigree method for plants/lines which had high seed germinability and vigor, high percentage and thickness of seed coat and good agronomic characters. The yield trial of 17 F5 lines was performed at National Corn and Sorghum Research Center in rainy season 2005. Six F5 lines having high seed yield, field weathering resistance and good agronomic characters were selected. These promising lines will be further evaluated for seed yield, field weathering resistance and agronomic performance in different locations. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Combining Ability of Inbred Lines Derived from Quality Protein Maize Populations) ผู้เขียน:ดร.พีรนุช จอมพุก, รองศาสตราจารย์ , ดร.วาสนา วงษ์ใหญ่, รองศาสตราจารย์, Somsak Apisitvanich, ดร.ชบา จำปาทอง สื่อสิ่งพิมพ์:pdf AbstractQuality protein maize (QPM) with improved kernel quality over o2o2 soft genotypes was developed by introducing modifier genes and selecting for a hard, vitreous endosperm in o2o2 germplasm at the International Maize and Wheat Research Center (CIMMYT). Three QPM populations developed by CIMMYT were used in the research. S0-plants of preferred morphological characters were selfpollinated to produce S1 until S3 lines. Ten S3 inbred lines were examined for the opaque-2 gene using the phi057 marker and a diallel cross was made. The experiment was conducted in a 7?7 simple lattice design at the National Corn and Sorghum Research Center, Thailand. The results showed that 10 inbred lines were detected with polymorphism the same as opaque-2 maize (o2o2) but were different from nonopaque- 2 maize. The protein content in endosperm of these inbred lines ranged from 7.76 to 8.61% while those of opaque-2 and non-opaque-2 maize contained about 8.45 and 8.73%, respectively. However, the protein content of inbred lines, the diallel cross and check variety were not significantly different. Means of grain yield (t ha-1) were 4.48 for the diallel cross (F1), 1.97 for inbred lines, 3.30 for opaque- 2 and 6.61 for non-opaque-2 hybrid check. However, grain yield of the best diallel cross was 6.10 t ha-1 which was not significantly different from the non-opaque-2 hybrid. Protein contents were not significant among the diallel cross, opaque-2 and non- opaque-2 hybrids. Tryptophan content in endosperm of the diallel cross was higher than non-opaque-2 hybrids. Inbred P10 had the best combination of GCA effects for grain yield. Moreover, inbred lines, P1, P7, P8 and P9 also gave positive GCA effects. |

หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Callus Induction and Plant Regeneration from Mature Embryos of Glutinous Rice (Oryza sativa L.) Cultivar TDK1) ผู้เขียน:Souvanh THADAVONG, ดร.ประภา ศรีพิจิตต์, รองศาสตราจารย์, ดร.วาสนา วงษ์ใหญ่, รองศาสตราจารย์, ดร.พีรนุช จอมพุก, รองศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractThe present study was conducted to determine the optimum in vitro conditions for callus induction and plant regeneration from mature embryos (seeds) of glutinous rice cultivar TDK 1. It was revealed that embryos cultured on Murashige and Skoog (MS) agar medium supplemented with 2 mg/l 2,4-D and 500 mg/l L-proline under light condition produced the highest percentage of callus formation (96.91 %). The average size of callus produced was large (6.02 mm). The calli dehydrated by placing in petridishes with covers for 7 days under light condition before transferring onto regeneration medium generated higher frequency of shoot regeneration than the calli cultured on regeneration medium without dehydration. The most suitable medium for plant regeneration from dehydrated calli was MS agar medium supplemented with 1 mg/l IAA, 4 mg/l BA and 800 mg/l casein hydrolysate which induced the highest percentage of calli forming shoots (45.00 %) and each callus produced the largest number of shoots (average 15 shoots). The shoots were rooted at the highest rate (100 %) when transferred onto MS agar medium supplemented with 1 mg/l NAA. The complete plantlets were thereafter transplanted to grow under greenhouse condition. They were morphologically normal and fertile. |
