 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Detection of Quantitative Trait Loci for Seed Size Traits in Soybean (Glycine max L.)) ผู้เขียน:Hamidreza Dargahi, ดร.พัชรินทร์ ตัญญะ, รองศาสตราจารย์ , ดร.พีระศักดิ์ ศรีนิเวศน์, ศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractDetection of validated and confirmed quantitative trait loci (QTLs) is essential to conduct more successful marker-assisted selection breeding programs. The objectives of this study were to determine the QTLs controlling seed size traits in soybean (Glycine max L.) and to compare those identified with the previously reported QTLs. One hundred thirty-five F2:3 lines derived from the cross MJ0004-6 ? R18500 were evaluated in the experimental fields of Kasetsart University, Kamphaeng Saen, Nakhon Pathom, Thailand in a randomized complete block design with two replications each in the 2011 and 2012 growing seasons. The population was genotyped by 149 polymorphic simple sequence repeat markers and the genetic map consisted of 129 simple sequence repeat loci which converged into 38 linkage groups covering 1156 cM of soybean genome. There were 16 quantitative trait loci (QTLs) significantly associated with seed size traits across two seasons with single QTLs explaining between 7.4% and 18.4% of the phenotypic variation. One novel QTL (SL6) on linkage group K was consistently mapped in both seasons. Most QTLs were environment-sensitive, revealing that the genotype ? environment interaction played an important role in expression of seed size traits in soybean. The majority of QTLs detected in the research were consistent with earlier QTLs reported by previous researchers. |

หัวเรื่อง:อิทธิพลของขนาดเมล็ดต่อความงอกในไร่การเจริญเติบโตและผลผลิตของถั่วลิสง ผู้เขียน:จวงจันทร์ ดวงพัตรา, Chokchai Kittitanasuan สื่อสิ่งพิมพ์:pdf AbstractThe effects of seed size on field emergence growth and yield of large-seeded peanut were studied in the two promising peanut lines : KUP24D-421 and KUP24D-084. Hand shelled dry peanut seeds from the sound mature pods were sorted into three different sizes using oblong perforated hand screens. Large seeds were those that remained on the 21.5/64 x 3/4 inch screen. Seeds that passed through the 21.5/64 x 3/4 inch screen and remained on the 18/64 x 3/4 inch screen were medium size, and those that passed through the 18/64 x 3/4 inch screen belonged to the small seed size group. If was found that moisture content of the small seeds were higher than that of the medium and large seeds but seed weight of the large seeded group were higher than the smaller one. Difference in seed germination and seed vigor was not found among different seed sizes, although the larger seeds gave higher seedling dry weight. Field experiment indicated that small peanut seeds germinated faster than the large seeds. It was also found that at the early growth stages, peanut plants planted from the small seeds were lower in plant dry weight than those planted from the large seeds. However, there was no difference in flowering date, pod yield, and seed yield among those peanuts planted from different seed size classes. It appeared that for the large-seeded peanuts, small seeds could be used for planting and keeping the large and medium seeds for consumption and peanut products. |
