Association Analysis for Economic Traits in Upland Cotton (Gossypium hirsutum L.)

Background: Gossypium hirsutum, the most widely cultivated crop in world has concurrent importance for both fibre quality and yield. Polygenes regulate cotton output a variety of factors affect characteristic. As result, it is essential to have thorough knowledge relationships between different component traits quality. Thus, aim study was framed know about correlation along with cause-and-effect relationship among economic traits. Mathod: Eight parents 56 hybrids made up experimental sample our study, which were evaluated 18 economically significant The conducted at Department Cotton, Tamil Nadu Agricultural University, Coimbatore, 2021-2022. Results: Analysis variance highly all studied. result revealed that viz., number bolls per plant, boll weight, seeds boll, upper half mean length strength had high magnitude positive seed yield genotypic phenotypic levels. Path analysis represented direct effects length, uniformity index, on Hence, these can be used as selection criteria improvement cotton.
