ASSOCIATION ANALYSIS UNDER SPACED AND DENSE SOWINGS IN WHEAT

Abstract

Segregating materials are usually space sown in early generations. However, the final evaluation for grain yield is done under thick sowings. Selection for grain yield and its comPonents under spaced planting has been found to be of little value [1, 2]. Very little efforts are made to expose the breeding materials to varied growing conditions before bulking. The present study, therefore, aims to assess the changes in phenotypic associations of ·different characters with grain yield under spaced and. dense plantings in three different agronomic conditions~ It would be useful to find traits that cOuld be depended upon for breeding imPi'o~ved varieties of wheat for various agronomic conditions.
