STUDY ON HERITABILITY AND CORRELATION ANALYSIS OF PRODUCTION AND FIBER CHARACTERISTICS OF UPLAND COTTON

Abstract

This investigation was performed to evaluate the heritability and correlation analysis of production and fiber characteristics for upland cotton (Gossypium Hirsutum L.). This experiment was performed at Agriculture Research Center Tandojam in (RCBD) with three replication and eight genotypes with one check variety. In this study the parameters observed height of plant, bolls plant-1, boll weight, sympodial branches plant-1 monodial branches plant-1, staple length showed highly significant at (<0.01) probability level. While the results for cotton seed production, sympodoial branches plant-1 and monopodial branches plant-1 and GOT% indicated at (>0.05) probability level. Among the eight genotypes, the TH-26/23 genotypes have maximum height of plant, smypodial branches plant-1, monopodial branches plant-1, cotton seed production and boll weight, while TH-23/23 had maximum number of bolls plant-1, sympodial branches plant-1, GOT%, monopodial branches plant-1 and boll weight. According to correlation the plant height had showed only significant favorable relationship with the monopodial branches plant-1, and height of plant showed significantly higher and beneficial relationship among boll weight, cotton seed production and GOT%. The monopodial branches plant- 1 indicated significantly higher relationship with the GOT%. The sympodial branches-1 showed significant relationship with staple length. Boll weight showed highly significant correlation with the seed cotton yield. The heritability in broad sense estimated high heritability for majority of the studied material which exhibited that characters should be improved through simple selection.
