Abstract

In order to investigate the effects of DROUGHT STRESS on YIELD and some agronomic and physioloyical characteristic in rapeseed (Brasica napus L.) cultivars a field experiment was conducted as split-plot arranged in a Randomized Compelete Block Design with four replications in 2002/3 of karaj-Iran (at:35°,59'Northen and 50°,75 estern). There were two factors, Irrigation at two levels (80 percent of evaporation as control and DROUGHT STRESS from stem elongation stage) as main plots and cultivars in 10 levels: Sarigol, Goliath, Heros, Comet, Arnica, Sw5001, Crackerjack, Eagle, Wildcat, Swhotshot as sub factor. The factors under study were: Biological YIELD, Grain YIELD, Harvest index, 1000Grain YIELD, OIL PERCENT, Number of lateral branches, Number of pod in main branch Number of pod, Pod lengh and PRALINE percent. Results showed that no significant difference on Biological YIELD, Grain YIELD, Harvest Index,1000 grain weight and OIL PERCENT between Cultivars, Irrigation levels and interaction effects. Eagle C.V. had maximum PRALINE percent(0.23%)at 1% level. Interaction effect of irrigation levels and cultivars showed that, on DROUGHT STRESS, maximum pod length (6.7cm) and number of lateral branches/plant (6.2) belonged to Arnica at 1% level. Maximum PRALINE percent belonged to Heros and Eagle C.V. (0.422%) at 1% level on DROUGHT STRESS. Heros and Comet cultivars had maximum grain YIELD with 3830 and 3620 kg/ha respectively on DROUGHT STRESS compared to other cultivars that may had a better adaptation to the DROUGHT STRESS.
