Heterosis and inbreeding depression of F2 segregating population for yield, quality and shelf-life characters in muskmelon

Abstract

This study investigates the dynamics of inbreeding depression and heterosis in a population of F2 muskmelon (Cucumis melo L.), focusing on various yield, quality, and shelf life traits. The research conducted at Dr. YSRHU-College of Horticulture, Anantharajupeta, explored traits such as fruit yield, quality and shelf life characteristics across 162 F2 plants derived from the selfing of F1 hybrids. Results suggest that traits like node of the first male flower emergence, titrable acidity and β-carotene suggesting they are primarily influenced by additive genetic effects, The study underscores the complexity of genetic interactions shaping muskmelon traits, offering insights for future breeding strategies aimed at enhancing yield, quality and shelf life traits.
