Study of correlation coefficient for yield and its components in spine gourd (Momordica dioica Roxb.)

Abstract

Twelve genotype of spine gourd (Momordica dioica Roxb.) were evaluated in a Randomized Block Design with three replications at Horticulture Instructional farm, COA, IGKV, Raipur (C.G) during Kharif 2018. Correlation coefficients were carried out to study the Character association and contribution, respectively for fifteen qualitative characters. Results of correlation coefficient analysis revealed that fruit yield per plant showed the highest significant positive association with number of branches per plant, number of fruits per plant, fruit length, fruit width and average fruit weight at both genotypic and phenotypic levels and had negative and significant association with days to first fruit harvest and fruiting periods. Hence, in selection programme, emphasis should be given on these traits for improvement in fruit yield of spine gourd.
