Comparative analysis of morphological and yield-related parameters in wheat varieties subjected to accelerated aging stress

Sunita Bhandari*

In this investigation four varieties of wheat viz. VL-829, VL-802, UP-1109 and VL-892 and were subjected for estimated the effect of accelerated ageing at 45°C and 100% relative humidity for 15, 30 and 45 days along with control. The experiment was laid out in factorial RBD with three replications of each treatment. Aged seed from different treatments control, 45, 30, and15 days accelerated ageing of each variety were subjected to field experiment for evaluating plant growth, seed yield and its contributing characters. Results showed decline in all yield attributes and growth parameters with increase in ageing period. Rapid decline in seed yield contributing characters were observed in VL-802 whereas, less reduction observed in VL-892.
