Genetic studies of correlation and path coefficient analysis for yield and fibre quality traits in cotton (Gossypium hirsutum L.)

Abstract

Sixteen Line × Tester hybrids were studied to better understand yield component relationships. The number of bolls per plant and boll weight had a substantial positive correlation and a high direct influence on seed cotton yield per plant, according to both association and route analysis analyses. Finally, selecting some features, such as number of bolls per plant and boll weight, directly impacts seed cotton yield per plant. Furthermore, number of bolls per plant had a substantially favourable indirect influence on number of sympodial branches per plant, micronaire value, and lint index through number of sympodial branches per plant, micronaire value, and lint index. The lint index had a significant indirect impact on the seed index. Selection based on these qualities indirectly increases seed cotton output per plant by a large margin. As a result, the yield and yield potential have improved. Key words: Path analysis, Cotton, Correlation co-efficient and Gossypium hirsutum L
