This investigation was conducted at El-Gemmeiza Agriculture Research Station farm, Gharbia
Governorate, Horticulture Research Institute, Agriculture Research Center through the three years 2020, 2021 and
2022. Simple recurrent selection was used to improvement of some quality characteristics in Sabeiny cabbage
populations. The data illustrated that the averages and ranges of characters for genotypes become greater in Sm
generation than those in the S0 and S1 generation. Highest significant differences were recorded between all
genotypes for traits. These results recorded that non - wrapper leaves number and days to harvest decreased by
27.65 and 13.57 % in the first cycle population. Meanwhile, wrapper leaves number, head weight and head diameter
increased by 5.98, 28.79 and 11.78 %. Phenotypic coefficient variances were greater than the genotypic coefficient
variances referring predominance of environmental actions on the expression of aforementioned traits. Highest
heritability coupled with high GAM % (genetic advance as percent of mean) were recorded in all traits, especially,
wrapper leaves number, head weight and days to harvest. The obtained results indicated that these characters were
under the control of additive gene action and could be effectually improved during selection. Head weight had
positive and significantly correlation at phenotypic and genotypic level with wrapper leaves number and head
diameter. Negative and highly significant correlations were estimated with days to harvest and number of non-
wrapper leaves and head length. Therefore, selection of a good cabbage in wrapper leaves number, head height,
head weight and head diameter, may improving cabbage plants under this study.
Keywords: Cabbage, variance, heritability, genetic advance, correlation, selection.
