Genetics analysis of some economic characters in cross in Egyptian cotton [Egypt]

Estimation of gene action through partitioning of genetic variance was carried out, using the parents, F1, F2 and F3 populations in the cross (Bahtim 105 x Giza 67) x Giza 75. Inbreeding depression and heritability in broad and narrow sense were also studied. The results showed that the nonadditive...

Summary:Estimation of gene action through partitioning of genetic variance was carried out, using the parents, F1, F2 and F3 populations in the cross (Bahtim 105 x Giza 67) x Giza 75. Inbreeding depression and heritability in broad and narrow sense were also studied. The results showed that the nonadditive portion was larger than the additive for yield of seed cotton, boll weight, and lint strength. The additive was larger than the non-additive portion for lint percent, seed index, lint index, halo length and lint fineness. Inbreeding depression was positive and significant for yield of seed cotton, boll weight, lint percent, lint index and halo length. Heritability estimates in broad and narrow sense were low for boll weight, and relatively high for the other traits.
