Abstract :

In order to evaluation of water stress at silique and grain filling stages on rapeseed cultivars, This experiment a factorial design of the study comprised of randomized complete block with four replications. There were two levels of conventional irrigation periods. Normal irrigation at 80 millimeter evaporation pan class A and water stress condition (discontinuing irrigation before siliqua formation). There were twelve cultivars of rapeseed: Celsius, Elvis, Sahara, Sunday, Slm 046, DS29955, Banjo, Olpro, Okapi, Opera, Herkules, Hyola 401. In this evaluation, most stages of plant phenology such as plant height, silique number in plant, seed number in silique, mean kernel weight, kernel yield, seed oil percentage and oil yield were measured. Results showed that Elvis with mean yield 5312 kg/h and oil 2270 kg/ha had superior points during two irrigation conditions. The difference of seed yield in two irrigation was 12% and in about oil yield water stress decrease 6% soil yield. Result showed that four genotypes of rapeseed including Elvis, Olpro, Sahara and Sunday were better than other in speed yield and oil seed during two type of irrigation.
