Character association path analysis studies in dicoccum wheat (Triticum dicoccum L.)

Abstract

A present investigation was undertaken to estimate the character association and path coefficient in 50 dicoccum wheat genotypes grown in randomized block design with two replications at Experimental Farm of Wheat and Maize Research Unit, VNMKV, Parbhani (Maharashtra) during rabi season 2023-24. The analysis of variance showed highly significant differences among the genotypes for all the characters. Grain yield per plant had recorded the significant and positive association with number of tillers per plant, spike length and number of grains per spike. Path coefficient analysis revealed that traits such as days to 50 percent heading, plant height, number of productive tillers per plant, spike length and number of grains per spike had positive direct effect on grain yield.
