A study on yield and yield components of twenty genotypes of sesame for planting in Southern Kerman Region

چکیده مقاله

The genetic diversity of sesame genotypes was studied by morphological traits in Southern Kerman Agriculture Research and Training Center in an experiment on the basis of a Randomized Complete Block Design including 20 genotypes with three replications. The studied traits were plant height, the height of the first capsule from the ground, capsule length, the number of first-order auxiliary branches, stem diameter at crown, the number of seeds per capsule, the number of capsules per plant, 1000-seed weight, leaf dry weight, stem dry weight, capsule dry weight and seed yield. It was found that the effect of genetic diversity was statistically significant on plant height, the height of the first capsule from the ground, stem diameter at crown, the number of capsules per plant, 1000-seed weight, leaf dry weight, stem dry weight, capsule dry weight and seed yield at the 1% level and on the number of seeds per capsule at the 5% level. The highest number of capsules per plant (78), 1000-seed weight (3.5 g) and seed yield (1020 kg ha-1) was produced by genotype 9. With respect to the yield and yield components, genotypes GL2, GL8,GL13, GL14 ,GH27 ,local dezful ,local behbehan ,local jiroft ,local kahnuj GL11 and darab one were categorized in the same statistical group in terms of the highest number of seeds per capsule, genotypes GL13 ,GL18 ,local dezful ,local kahnuj and varamin 237 were categorized in the same group in terms of the highest number of capsules per plant, genotypes GL2, GL8, GL11, GL18, GH27, local dezful, local behbehan, local kahnuj, local jiroft and varamin 237 were categorized in the same group in terms of 1000-seed weight, and genotypes GL18 ,GH27 ,GL14 and local dezful were categorized in the same group in terms of the highest yield.
