Abstract

The present study was aimed at finding out the planting dates effects on yield associated traits and also determining the variations of correlations among the traits in different planting dates of rapeseed genotypes. Significant planting dates and genotypes effects for phenological traits, yield components, seed yield and oil percentage revealed significant differences of planting dates and genotypes for these traits. Plant height had positive effect on pods per plant by increasing number of branches in each plant and length of main raceme. 1000-seed weight had significant positive correlation with seed yield, so any changes for this trait had considerable effect on seed yield. The variation of correlation between duration of flowering and pods per plant was less than the correlation of duration of flowering to other traits in different planting dates, so it can be used as selection breeding criterion.
