Path Analyses of Yield and Yield Related Traits of Thirty Four Diverse Tea (Camellia L. sp.) Genotypes

S. Babu    

Abstract: An association analysis was carried out to obtain and interpret information on the nature of interrelationships between yield and yield related traits. Thirty four tea genotypes were used in this study to represent the high levels of correlation of four traits that were identified as important yield determinants such as dry weight of shoot, fresh weight of shoot, number of shoots/plant and leaf breadth. The inter correlation values were found to be highly significant, hence further partition the values by path analyses was carried out to have a more accurate selection of characters for improving the yield. Among the traits studied leaf breadth, dry weight of shoot and number of shoots/plant were found to have high positive direct effect on yield/plant. Based on both the correlation and path coefficient values, it is interesting to know that dry weight of shoot is a possible consideration for the direct selection of high yielding genotype in the early generation where the yield test is not being conducted.
