Inheritance of Lint Weight Per Boll in Specific and Interspecific F1, F2 Hybrids in Cotton

Abstract

The experiment aimed to study the inheritance patterns of lint weight per boll in F₁ and F₂ hybrids. The parental forms, including varieties and lines, were reciprocally hybridized to analyze the impact on lint weight per boll. The results showed variations in lint weight among the parental forms and their hybrids. No heterosis was observed in F₁ hybrids with similar lint weight per boll. Positive and negative dominance patterns were identified in F₁ hybrids involving different parental forms. In F₂ hybrids, transgressive variability and genetic contributions were observed, indicating potential for selection and breeding. The results suggest that distant parental forms and gene combinations influence the lint weight per boll in subsequent generations.
