2004

This study was carried out to compare different characters of 21 selected lines based on preliminary experiments along with Darab 14 cultivar as control. During cultural seasons, different character like germination, flowering and maturing dates, numbers of minor branches, number of capsules per plant, number of seed per capsules, plant hieght, distance from soil level to appearance of first capsule. Tolerances and relation to pillory and wilt diseases were recorded. after harvesting the 1000 seeds weight, oil percentage and total yield were measured. The results of data analyzing showed there is a significant differences between control and other Lines and also among target Lines at level of 1%. The JL16 and JM40 lines with total yield of 1446 and 1629 kg/ha respectively showed the highest amount of yield. The results showed there is a positive correlation between yield and under studied characters. The correlation between the number of capsules per plant and seed yield was high (r = 0/59) showing the important role of the number of capsules per plant on seed yield. The JM40 and JL16 lines with highest production of capsules (172/5 and 169 respectively) per plant allotted the highest amount of seed yield themselves. The next important character was the numbers of seed per capsule and showed the positive correlation with seed yield (r = 0/36). In this case the JL21 and JM40 the with the average of 76/8 seeds per capsules showed the highest score. The maximum and minimum seed oil percentage was recorded 53/16 and 49/27% and was belonging to the JM40 and Jl11 respectively. Among the yield components, the 1000 seeds weight showed the lowest correlation with seed yield. In term of minor branch production, all genotypes were poly branch, but there was a significant differences among them, while the JM41 with 4/9 side branches showeed the highest numbers.
