الملخص الإنجليزي

Tomato is one of the most important vegetable crops grown in Egypt.

We aimed to investigate the genetic variability parameters, heritability, genetic advance, and correlation coefficient analysis for some important traits.

Therefore, we evaluated the cross Ms35 × I-4, along with its parents and F2 generation, at Ad-Daljamun village, Kafr El-Zayat, Egypt, during the 2017 summer season.

High genotypic coefficient of variation (GCV) was found for average fruit weight, number of fruits per plant, and weight of fruits per plant.

Heritability in broad sense was very high for number of fruits per truss, number of days to 50% mature fruits, average fruit weight, total soluble solids content, number of fruits per plant, and weight of fruits per plant.

The genetic advance as percentage of the mean (GA%) was high for number of flowers per inflorescence, number of fruits per truss, average fruit weight, number of fruits per plant, and weight of fruits per plant.

Generally, average fruit weight, number of fruits per plant, and weight of fruits per plant, had high values of genotypic coefficient of variation, heritability, and GA%, therefore, they are important for the direct selection.

The correlation coefficient analysis indicated a high association between weight of fruits per plant and average fruit weight, also, between number of fruits per plant and each of number of inflorescences per plant, number of flowers per inflorescence, and number of fruits per truss.

Moreover, a high correlation was found between number of flowers per inflorescence and number of fruits per truss.
