Abstract:
The experiment was undertaken to study the correlation and path coefficient analysis for yield and yield attributing traits. Total of eight wheat genotypes were grown in Randomized Block Design along with three replications at Research Farm, Department of Genetics and Plant Breeding, School of Agriculture, Lovely Professional University, Phagwara, Punjab, India. The resultant analysis of variance revealed that treatments were significant for all the characters. The value of PCV was much higher than GCV for all the traits signifying varying expression of traits was due to both genotype as well as environment. High GCV and PCV value was recorded only for ear weight. Low heritability accompanied with high magnitude of genetic advance was observed for biological yield/plant indicates the trait was governed by additive gene effect but low heritability observed due to high environmental effects, so selection may be effective only to a certain extent. The correlation coefficient estimated positive and significant genotypic and phenotypic correlation for harvest index and ear weight, while negative and significant correlation between day to 50% heading and grain yield/plant. The path coefficient analysis showed highest positive direct effects for harvest index followed by biological yield/plant, days to maturity, plant height, ear weight, number of grains/plant and 1000 grain weight on the dependent character. Whereas highest negative direct effect imposed by ear length followed by number of ears/plant, number of productive tillers/plant, days to 50% heading and number of spiklets/plant.
