Interrelationship studies for yield and yield attributing traits in elite genotypes of bitter gourd (Momordica charantia L.)

Abstract

Bitter gourd (Momordica charantia L., 2n=2x=22) is a dicot climber belonging to the cucurbitaceae family. Present investigation was carried out at Vegetable Research Farm of Department of Horticulture, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, India during the kharif season of 2014. The present experiment was under taken with 20 genotypes in Randomized Complete Block Design (RBD)in three replications. The yield of the crop is a complex character and is the ultimate product of action and interaction of various component characters. Taking the phenotypic correlation coefficient into consideration in the present investigation, characters namely node number of first staminate flower appearance (0.321), node number of first pistillate flower appearance (0.472), vine length (0.338), fruit circumference (0.613), fruits per plant (0.467), average fruit weight (0.641), fruit diametre (0.491) and internodal length (0.225) are positively and significantly correlated with yield per plant while on the other hand, days to anthesis of first staminate flower (- 0.302) and days to first harvest (- 0.294) are negatively and significantly correlated with yield per plant. © 2017, SPR, All Rights Reserved.
