Abstract
An investigation was carried out with 25 rabi sorghum genotypes to assess the association of grain yield components on grain yield per plant. Results of correlation analysis indicated that the grain yield per plant was found to be significant and positively correlated with panicle weight, harvest index, 100-seed weight and panicle length. Dead heart percentage showed significant negative association with grain yield per plant. The present study indicated that panicle weight, harvest index,
100-seed weight and panicle length are important characters in deciding the grain yield per plant. These characters may be considered as selection indices in sorghum breeding programme.
Key words : Rabi sorghum, correlation, grain yield.
Introduction
Sorghum (Sorghum bicolor L. Moench) is one of the most important drought tolerant crops which allows farmers to use one third less water than similar crops such as corn. The area under rabi sorghum is fairly consistent over many years but the progress in productivity is much slower compared to kharif season. Yield is a complex character, which depends upon many independent contributing characters. Knowledge on type of association between yield and its components themselves greatly help in evaluating the contribution of different components towards yield, information on the nature of association between yield and its components help in simultaneous selection for many characters associated with yield improvements. In the present study, such analysis has been carried out with 25 rabi sorghum genotypes. Materials and Methods
