 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Identifying Quantitative Trait Loci for Fiber Content and Fiber Components in Sugarcane Using Amplified Fragment Length Polymorphism Markers) ผู้เขียน:วารีย์ เวรวรณ์, ดร.เรวัต เลิศฤทัยโยธิน, รองศาสตราจารย์ , ดร.ชัยณรงค์ รัตนกรีฑากุล, รองศาสตราจารย์ , ดร.ธานี ศรีวงศ์ชัย, รองศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractThe cane yield, fiber content and fiber components (cellulose, hemicellulose and lignin) were determined from the segregation of 171 hybrid sugarcane clones derived from crossing K 84-200 and Kps 94-13 at 12 mth after planting. The results revealed that the average cane yield and fiber content in the hybrid sugarcane clones were 11.54 t.rai-1 (1 rai = 0.16 hectare) and 12.66%, respectively. The bagasse or fiber consisted of cellulose, hemicellulose and lignin with values of about 37.88–47.75, 30.15–40.73 and 4.81–10.23% dry weight, respectively. For amplified fragment length polymorphism identification, a total of 107 simplex markers were used to analyze the inheritance of quantitative trait loci (QTLs) for fiber, cellulose, hemicellulose and lignin contents. Eleven putative QTLs from the simplex markers were identified for these four traits. Each QTL explained from 2.5 to 4.3% of the variation in the fiber content. In parts of the fiber components, each QTL explained from 3.3 to 5.6% of the variation in the cellulose content and 2.3 to 3.0 % in the hemicellulose content, while the QTL explained 2.4 to 5.0 % of variation in the lignin content. Moreover, there were two putative QTLs related to more than one trait. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Identifying QTLs for Fiber Content and Agronomic Characters in Sugarcane Using AFLP Markers) ผู้เขียน:Somwung Anusonpornpurm, ดร.เรวัต เลิศฤทัยโยธิน, รองศาสตราจารย์, Chinarong Rattanakreetakul, ดร.อรินทิพย์ ธรรมชัยพิเนต, ศาสตราจารย์ , นายพิพัฒน์ วีระถาวร สื่อสิ่งพิมพ์:pdf AbstractSugarcane is a highly complex poly-aneuploid, heterozygous, interspecific polyploid and cultivars commonly have over 100 chromosomes. The population of 168 progenies from a cross between a sugarcane commercial variety (K 93-207) and a S. spontaneum clone (MPT 97-1) were evaluated in a replicated field trial. Stalk diameter and tillering were recorded at harvesting and subsequently plant material was evaluated for fiber content. Clones were significantly different (P<0.01) for all traits analyzed. A total of 180 AFLP simplex markers were used to analyze the inheritance of quantitative trait loci (QTLs) for stalk diameter, tillering and fiber content. Thirty putative QTLs from the simplex markers were identified for these three traits. Each QTL explained from 3.7 to 10.7% of the variation for stalk diameter and 3.7 to 9.9% for fiber content. For tillering each QTL explained from 4-8% of the variation. K 93-207 contributed a positive effect to the QTLs for stalk diameter and a negative effect for the QTLs for fiber content and tillering. MPT 97-1 contributed a negative effect to the QTLs for stalk diameter and a positive effect for fiber content and tillering. Ten of the QTLs from both parents were identified as contributing to more than one trait. However, these markers were not available for all parts of this very highly complex genome. Further work will be needed to identify more markers in this population. |
