In order to investigate the genetic parameters for the elephant (11) of cabbage genotypes, various combinations of genotypes have been examined in the vegetable research field, which is connected to Dept. of Horticulture and Landscape Design, College of Agriculture and Forestry, Univ. of Mosul, throughout the fall growing season 2021/2022. Using an analysis of variance table, results have shown that, at the 5% probability level, the genotypes had considerably differed among themselves in the majority of attributes that were evaluated. In addition, Broutis genotype did better than the other genotypes with regard to head weight and length as well as abscess leaf diameter, whereas the Ruby ball genotype performed better than the other genotypes with regard to abscess leaf diameter and head weight and length. Features of the overall yield per unit area compared to the remaining genotypes. With the exception of the trait of percentage of total dissolved solids, which has been very low, the traits of diameter, length, and yield per ton per unit area had high phenotypic variance (δ2p) and genetic variance (δ2g), has been high for most of the traits studied and the rate of heritability in the broadest sense(H2b.s.) more than 80%. The total yield has been associated with r=0.496, r=0.387, and r=0.369, respectively, the area unit exhibits a strong positive genetic and phenotypic connection with internal stem length, TSS, and internal stem length.
