بررسی عملکرد دانه و پایداری ژنوتیپهای کلزا تحت شرایط دیم‌ گرمسیر

Development of oil seed crops is the most important aims in country to reach self sufficiency. This research performed in 6 environments. 19 genotypes were compared in RCBD with three replications in 6 environments under rain fed conditions. Each plot had 5 rows 5-meter long. Observations were made on phonology, morphology and physiology traits during crop growth and after harvesting. Combined analysis results indicated that there were significant differences at 1% probability level among environments for all studied traits and there were significant differences at 5% probability level among genotypes for days to 50% flowering and plant height and at 1% probability level for number of seed per pod. Genotype × environment interactions showed significant differences at 1% probability level among genotypes for all studied traits exception of plant height. In general, RGS003, Option500 and Shiralee were advised for seed yield in Fall planting under rain fed conditions because they had line slope lower than 1 and seed yield average more than total average and also they included deviation variance from line non significant and low. Meanwhile, these genotypes involved stability gens; this means that we can use them as stable genotypes in breeding programs.
