CROSSING AMONG SOME MELON INTRODUCED GENOTYPES FOR OBTAINING NEW HYBRIDS WITH BEST YIELD AND QUALITY

Abstract

This study was conducted during the period from 2012 to 2014 at Kaha Vegetable Research Farm (KVRF), Qalubia governorate to evaluate six introduced genotypes of melon (PI 414723, PI 124111, PI 140471, PI 313970, PI 124112, PI 140417) and their diallel F1 hybrids in summer planting season. The results showed that the introduced genotype (1) and the hybrids 2x1 and 2x4 recorded the highest significant values for average plant length compared to the other introduced genotypes and the hybrids in summer season 2014 without significant differences between them 4x1, 5x3 and the hydride Primal produced the highest significant TSS values over all evaluated introduced genotypes and hybrids without significant differences between them. genotype 4 and hybrid 3x1 recorded the lowest significant TSS values, 6 The introduced genotypes and hybrids displayed the largest number of relevant fruits per plot (82) among all genotypes and hybrids introduced , but the lowest significant Fruits number per plot was found in 1x4 and 3x1. without significant differences between them. Mean while, the hybrid 4x5 produced the highest significant total yield per plant over all evaluated introduced genotypes and hybrids.
