Association Analysis for Yield Components InUpland Cotton (Gossypium Hirsutum L.)*

Abstract

Yield in cotton, like in all other crops, is a complex trait. It is mainly dependent on its component characters like boll number, boll weight, and seed index. It is, therefore, important to know the type and magnitude of association among yield and its components to breed a Better-yielding variety. A large majority of interrelationship studies have been conducted on varieties (Singh et al. 1968) and only a few on segregating progenies from crosses. In the present investigation two populations, an intermated one and the other plain F3 were used to assess the degree of association in upland cotton. It will provide an indication fbr future use ofintermating in a segregating population by comparing their degrees of association. An increase in positive correlation on intermating could be exploited for breeding better performing varieties.
