| Abstract | ||||
| In the present investigation, the first (81) and second (82) selective generations were produced by selection from Ismailawy sweet melon population, 81 and 82 were planted under the two planting methods drep irrigation and balee. The genotypic and phenotypic coeffident of variability and the narrow sense heritability and the expected gain under selection were estimated. Partial and multiple linear correlations were also calculated between some important traits. The results showed that the genotypic and phenotypic coefficient of variability were nearly equal for fruit diameter, fruit shape index and fruit flesh thickness in S1 and for fruit length and fruit flesh thickness in S2. Narrow sense heritability was high for number of fruits I plant, total yield I plant and total soluble solids of fruit Highly significant and positive correlations were detected between number of fruiVplant and total yield/plant, fruit weight and total soluble solids of flesh, fruit length and fruit flesh thickness. These results may help in selecting the proper breeding program for improving Ismailawy sweet melon. | ||||
