Assessment of Correlation and Path Coefficient Analysis in Bread Wheat (T. aestivum L.) for Yield and Its Related Characters

Twenty eight wheat genotypes (T. aestivum L.) were evaluated to estimate the correlation and path coefficient analysis for yield and yield contributing traits. The genotypes were sown in randomized block design with three replications during Rabi seasons of 2019-20 and observations were recorded for each genotype in each replication for all eleven studied characters. Days to heading showed positive and significant correlation with days to 50% anthesis, plant height, biological yield per plant, grain protein content and grain yield per plant; days to anthesis showed significant and positive correlation with days to heading, grain protein content, plant height and biological yield per plant; plant height positive and significant correlation with days to heading, days to anthesis, spikelets per spike and it also showed negative correlation with number of tillers per plant and 1000 grain weight. Grain yield per plant was significant and positively correlated with days to 50% heading and biological yield per plant whereas it also showed significant negative correlation chlorophyll content. Furthermore, the path coefficient analysis reviled that biological yield per plant and harvest index showed positive and direct effects toward the seed yield per plant and for rest of the characters their magnitude were low to very low.
