Abstract

 In order to study the effects of heat and drought at the end of the season, on YIELD and YIELD components of some agronomic traits in sixteen CANOLA varieties, this experiment was carried our in Behbahan (30o, 37’ N and 50o, 16’ E) Institute research. The experimental design analysis of combined in completly randomized block basis cration four condition to plant growth by different planting date and cut irrigation in the late staye the end of plant life. The four create condition were planting date at: 1-20 November, 2-20 November with cut the last irrigation, 3-20 December and 4-20 December with cut the last irrigation. Three replication was used in this experiment. Results showed that GDD on different humidity level or four condition at the flowering was different. Also flowering period in different condition showed the significant different. HEAT AND DROUGHT STRESS induced significant different (1% permability level) between four condition for seed YIELD, number pod per plant, number seed per pod, flowering starting time, oil percentage, oil YIELD. in four level difference Number pod per plant had the highest correlation with seed YIELD (83%), while there was not a significant correlation between YIELD and seed. Hyola variety had the highest YIELD therefor this variety recommended to all area same experimental place condition.
