Correlation studies on seed cotton yield and its components in upland cotton (Gossypium hirsutum L.)

As the crop yield is influenced by large number of components, present investigation was undertaken to determine their importance in productivity of upland Cotton (Gossypium hirsutum L), in order to initiate an effective selection program. For this purpose, correlation studies were employed wherein seed cotton yield per plant was taken as dependent character. The boll weight recorded significant positive association with seed cotton yield per hector (0.2877 and 0.6231) at phenotypic and genotypic levels respectively. Seed index showed significant positive correlation with seed cotton yield per hector, (0.3938 and 0.5973) at phenotypic and genotypic levels respectively. At phenotypic level, lint index showed significant positive correlation with seed cotton yield per plant (0.2988), and seed cotton yield per hector (0.2532). This trait showed significant positive correlation with seed cotton yield per plant (0.5646) atgenotypic level.
