 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:การเปรียบเทียบวิธีการคัดเลือกเพื่อปรับปรุงประชากรข้าวฟ่าง มก.8 ผู้เขียน:Watcharin Soonsuwon, ดร.กฤษฎา สัมพันธารักษ์, ศาสตราจารย์ , ดร.วาสนา วงษ์ใหญ่, รองศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractA comparison of three population improvement methods was conducted by using S1 seed, sibbed seed and S2 seed of selected S1 lines for a recombination of new cycle. Three hundred S1 lines were selected from KU. Pop.8C0 snd tested in the progeny trial. The best 3-5 female plants and 3-5 male plants from each line were sibbed and selfed to form sibbed seed and S2 seed. Thirty-three S1 lines and their respective derived sibbed seed and S2 seed were chosen to form three new populations namely, KU. Pop. 8(S1)C1, KU.Pop. 8(Sib) and KU.Pop. 8(S2) C1. Resulted data proved that S1 seed and its derived sibbed seed and S2 seed were very effective for increasing grain yield of new cycle populations. The highest yielding population was KU.Pop.8(S2)C1 which yield 5.82 ton/ha followed by KU.Pop.8(Sib)C1, 5.72 ton/ha and the lowest yielding population was KU.Pop.8(S1) which yielded 5.59 ton/ha. However, the yield of three new populations were not different statistically. KU.Pop.8(S2)C1, KU.Pop.8(Sib) C1 and KU.Pop.8(S1)C1 yield 11, 9 and 7 percent over KU.Pop.8C0 , which was used as the original check population, respectively. The new populations were also improved for serveral other agronomic traits, such as higher 1,000 seed weight, higher shelling percentage, shorter panicle length, less lodging percentage and less leaf diseases. |
