| Abstract | Inheritance of shatter resistant capsule in sesame was studied in F2 populations of three crosses of sesame using chi-square test for goodness of fit. The ratios obtained for shatter resistance:shattering are 15:1 and 9:7 for the cross between shatter resistance x shatter resistance (C plus 1 x KUsr6661) and between shatter resistance x indehiscence (C plus 1 x UCR5001), respectively. The results indicated that shatter resistance is caused by two pairs of genes with duplicate dominant epistasis and duplicate recessive epistasis, respectively. But the cross between shatter resistance x shattering (C plus 1 x KUAOX 25) is nearest to 9:7 model, suggesting that the genetic control is not duplicate recessive epistasis. The shatter resistance in the three crosses was highly heritable with narrow sense heritability of 0.74, 0.73 and 0.68, respectively. The results suggested that improvement of sesame lines for high seed yield with high shatter resistant capsules or high seed retention in capsules could be successful. |
