 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Yield Partitioning in High Yielding Mungbean (Vigna radiata (L.) Wilczek)) ผู้เขียน: G.S.S. Khattak,  ดร.พีระศักดิ์ ศรีนิเวศน์, ศาสตราจารย์ , D.H. Kim สื่อสิ่งพิมพ์:pdf AbstractCorrelation and path-coefficient were studied in 10 mungbean (Vigna radiate (L.) Wilczek) genotypes. Positive correlation was observed between grain yield and 1000-seed weight. Branches per plant was negatively correlated with grain yield. Correlation between branches per plant and 1000-seed weight was negligible. The path-coefficient analysis indicated that 1000-seed weight had a high total correlation and a high direct effect on grain yield. Direct contribution of seed size toward grain yield was the highest, but it was appreciably influenced via pods per plant, days to maturity, plant height and clusters per plant. Despite the highest total negative correlation between branches per plant and grain yield per plant, the direct effect was negligible. Clusters per plant had no correlation with plant yield. Ultimately, 1000-seed weight alone qualifies as the best index for selection of genotypes in a mungbean breeding program. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Effect of Mungbean Yellow Mosaic Virus (MYMV) on Yield and Yield Components of Mungbean (Vigna radiata (L.) Wilczek)) ผู้เขียน:G.S.S. Khattak, M.A. Haq, S.A. Rana, G. Abass, M. Irfag สื่อสิ่งพิมพ์:pdf AbstractFourteen MYMV susceptible F3 progenies from a cross NM 92 x VC 1560D showed significant differences for MYMV disease infection, yield and yield components. These progenies suffered from 18.5 to 40.5 percent decrease in plant height, 11.7 to 64.0 percent reduction in number of pods per plant, 5.8 to 82.2 percent reduction in seeds per pod, 7.4 to 35.0 percent decrease in pod length, 10.6 to 53.3 percent reduction in 1000 seed weight and 32.2 to 78.6 percent decrease in grain yield per plant. The MYMV incidence showed significant correlation (0.526) with the decrease in 1000 seed weight. The decrease in yield and other yield components showed non significant positive correlation with MYMV incidence. |
