Correlation Analysis for Seed Yield and Its Contributing Traits in Isabgol Genotypes

Abstract

The present investigation was carried out at main experiment station Horticulture, Department of Horticulture, NDUA&T, Kumarganj, Faizabad (U.P.) to study the correlation analysis for seed yield and its contributing traits on 42 genotypes of Isabgol. The experiment was laid out during rabi season (2011-12) in randomized block design replicated twice with the plant spacing 30x10 cm. The study revealed that the seed yield per plant was highly significant and positively correlated with number of spike per plant (0.628), while it had significant and positively correlated with number of branches per plant (0.342). On the basis of genotypic and phenotypic correlation coefficient, which is good indicator for selection is can be concluded that to increase the seed yield per plant, the character number of spikes per plant must be considered because these characters had highly significant and positive correlation with seed yield per plant. Therefore, direct selection for number of spike per plant would be effective for seed yield improvement in Isabgol.
