Abstract: In order to get the heritability index in flesh texture of testing varieties, as well as estimate combined heritability and narrow sense heritability, the variety of ‘Guibao’ was used as testing variety to calculate combined heritability and narrow heritability of crisp flesh texture trait of different combinations by method of parent-child regression coefficient estimation. The results showed that when ‘Guibao’ was the male parent, ‘Christmas Rose’ topped the heritability index of crisp flesh texture trait, ‘Ruby Okuyama’ was the second and ‘Muscat Hamburg’ was the minimum. When ‘Guibao’ was the female parent, the flesh texture of hybrids was connected with the male parent. The order of seven varieties’ heritability indexes of crisp flesh texture trait was ‘Christmas Rose’＞ ‘Autumn Royal’＞ ‘Taifei Rose’＞ ‘Flame Tokay’＞ ‘Centenniai Seedless’＞ ‘Tamina’＞ ‘Muscat Hamburg’. According to the heritability comparison among different hybridized combinations, for the combination heritability, soft flesh× crispest flesh was the highest, the crisp flesh× near crisp flesh was the second, while the near crisp flesh× soft flesh was the lowest. Through the method of parent-child regression coefficient estimation, the narrow heritability of crisp flesh texture (h²) was calculated as 0.9816. Analysis showed that crisp flesh texture possessed considerable heritability. Estimation of the heritability index in flesh texture and the combined heritability of grape can be the guidance for breeding and parent choice.
