摘要

This study was explored in order to determine the effects of various agronomic traits on single plant seed yield in sesame using correlation and path coefficient analysis. Nine diverse accessions of sesame were grown in a two-year potted field experiment and were completely randomized with twelve replicates. Simple correlation and path analysis were carried out in order to determine the relationships between agronomic characters and estimate their direct and indirect influences on the single plant seed yield. Positive and statistically significant (p<0.01) relationships were established between single plant seed yield (g) and leaf nodes per plant, number of pods per plant, number of pods per main stem, breadth of pod, number of seeds per pod, 1000-seed weight and number of seeds per plant. Path analysis revealed that the number of seeds per plant and 1000-seed weight had the highest direct influence (i.e., 1.325 and 0.578, respectively) on single plant seed yield while the number of pods per planthad the highest indirect effect (1.175) through the number of seeds per plant. These results indicate that number of seeds per plant, 1000-seed weight and number of pods per plant can be good selection criteria for single plant seed yield in sesame.
