Role of yield components and other traits in determining the seed yield of common bean under different planting dates and densities using step-wise regression and correlation coefficient.

摘要

In order to determine the importance of role of seed yield components and other measured traits in the determination of seed yield in different dates and densities of common bean line 1-61-57, a field experiment was conducted in Dehaghan County during two agronomic years. The experiment was carried out as twice split plots in a randomized complete blocks design with three replications. The results showed the correlation between the number of offshoots and seed yield and also the correlation between the number of pods per plant and seed yield were very meaningful. The pattern of seed yield illustrated that the number of pods per plant, the days required for reaching the physiologic maturity, the number of offshoots and ultimately the plant height played the most major role in determining the seed yield of common bean line 1-61-57, according to importance.
