CORRELATION AND PATH COEFFICIENT ANALYSIS IN IVY GOURD (COCCINIA GRANDIS)

Jumi Saikia

Abstract

An experiment was conducted to study the correlation and path coefficient analysis in ivy gourd ( Coccinia grandis ) genotypes collected from different parts of Assam and other North Eastern States (Arunachal Pradesh, Tripura and Nagaland) during the summer seasons of 2013 and 2014. The experiment was laid out in Randomized Block Design with three replications at the Experimental Farm, Department of Horticulture, Assam Agricultural University, Jorhat. The correlation analysis revealed that yield per plant had significant positive correlation with number of primary branches, fruit length, number of fruits per plant and fruit weight. From the path coefficient analysis, it was observed that number of fruits per plant had the highest positive direct effect (1.1928) on yield. Number of primary branches had the highest positive indirect effect on yield via number of fruits per plant (1.1491). The residual effect was 0.1097 which was within a reasonable limit indicating that the characters included in path coefficient analysis were adequate in explaining the variation in ivy gourd.
