| This research was carried out in split plot experiment based on randomized complete block design with three replications at Behbahan Agricultural Research Station for two years (2011–2013). The main plot consisted of sowing times 26 June, 11 July and 26 July and sub plot was five genotype L5-84215, L5-86365 and Safiabadi lines, Yellow white cultivar and Behbahan local population. Two years combined variance analysis results showed that the effects of sowing time, genotype and interaction effects of sowing time and genotype were significant on seed yield and yield components. The heightest seed yield in the first and second years was produced on 26 June and 26 July sowing times (1281 and 889 kgha-1, respectively). The heightest seed yield was produced by Behbahan local population and Yellow white cultivar (1417 and 1151 kgha-1 in the first year and 916 and 752 kgha-1 in the second year, respectively). The results of interaction effects of sowing time and cultivar showed that in the first year the heightest seed yield was produced by Behbahan local population and Yellow white on 26 June sowing time (1688 and 1449 kgha-1, respectively) and in the second year the heightest seed yield was also produced by Behbahan local population and Yellow white on 26 July sowing time (1217 and 982 kgha-1, respectively). Seed yield of all genotypes in the first year decreased from 26 June 26 July sowing times. Due to the damage of charcoal rot disease on 26 June and 11 July sowing times, the heightest seed yield was produced on 26 July sowing time in the second year. The heightest and the lowest seed yield of genotypes in the second year was produced on 26 July and 26 June sowing times, respectively. Therefore, due to the possibility of outbreak of charcoal rot disease at the end of June to mid July, planting of Behbahan local population and Yellow white cultivar at the end of July is recommended in Behbahan region. | ||
