Evaluation of yield and yield components of hopeful hybrids of spring canola, Brassica napus in Iranshahr climatic condition

In order to evaluate the adaptability, yield and yield components of 12 hopeful hybrids of spring canola in Iranshahr climate, an experiment was conducted in a randomized complete block design with four replications in agricultural and natural resources research center of System and Balouchestan province during 2005-2006. Results showed significant differences of genotypes in plant height, thousand seed weight, number of pods per plant, number of seeds per pod, number of days to flowering, the length of flowering period, the length of ripening period and numbers of days to harvest. Hyola 401 had the most grain yield, thousand kernel weight, oil percent and yield than other hybrids. Hyola308/3 indicated the least grain and oil yield. However, the higher percent of seed oil, plant height and numbers of pods per plant were observed in this hybrid. Hyola308 and syn-2 had more numbers of seed per pod than others. Syn-3 indicated longer flowering period. Hyola308 and Hyola 420 had the higher length of ripening period and hyola43 indicated longer growing period. Thousand kernel weight and the length of ripening period after flowering showed positive correlation with grain yield and oil yield. Length of growing and flowering periods had also negative significant correlation with oil and grain yields in this experiment. Based on the results, the most grain yield was obtained from Hyola 401 and Hyola308. Whereas, Hyola308/3 and Hyola330 produced the least grain yield.
