Abstract:
The effect of four different dates of sowing on phenological, growth and yield traits were studied using eleven rapeseed and Indian mustard varieties at IARI, New Delhi. Exposure to different temperatures at vegetative, reproductive and maturity stage was provided by sowing the seeds in different planting window (D1:19 Sept.; D2:12 Oct.; D3:2 Nov.; D4:22 Nov.) Here we report the effects of species, line (belonging to early, timely and late sown group) and environment (different dates of sowing) on seedling emergence, flowering, plant growth and yield related traits. The results indicated specific, genotypic variation as well as different response to the environment, resulting from strong G×E interactions for these traits. All the temperature variables were negatively correlated (r = -0.773 to -0.676) with days to flowering i.e. delayed sowing delays the flower initiation too. Flowering duration was significantly negatively correlated (r = -0.762 to -0.794) with the temperature variables in the reproductive stage. Similarly, days to maturity was significantly negatively correlated (r = -0.404 to -0.435) with all the temperature variables during seed filling and maturity stage. Number of primary branches showed a significantly positive correlation (r =0.459 to 0.506) with temperature variables in the vegetative phases.
