TI - Genotypic stability and phenotypic adaptability for some yield traits in some long staple cotton genotypes KW - Cotton KW - Genetics KW - Yields KW - Quality N1 - Includes references N2 - The development of genotypes, which can be adapted to a wide range of diversified environments, is the ultimate goal of plant breeders in a crop improvement program. A multilocation experiment was performed to study genotype by environment interaction (GEI) using different stability parameters. Twenty two genotypes obtained from the Egyptian cotton breeding programme, besides two check varieties were evaluated for seed cotton yield and lint yield stability under five locations in the Delta region of Egypt. The results showed that variances due to genotypes, environments and genotype x environment interaction were highly significant for both traits, which indicated that these genotypes interacted differentially with environments. The environmental variation caused more than 60% of the total variance on these genotypes, while the genotypes variations cause 3.96% and 4.341% for seed cotton yield and lint yield, respectively. Seven stability parameters were used to determine stability of these genotypes UR - http://nile.enal.sci.eg/EALE/2015/EJAR/9315/1/85.pdf ER -
