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. |
