Abstract:

The present investigation aimed to determine stability parameters of some Egyptian cotton genotypes i.e. Giza 80, Giza 90, L1 ( G.90 x Australy ) , Giza 95, L2 [G.80 x Australy] x G.83, L3 [G.83 Raid x Australy] x G.91, L4 [G.83 x (G .80 x G .75 )] x Karashenky and L5 [G.83 x (G .80 x G .89 )] x Australy under 4 environments (two locations and two successive years, 2015 and 2016) . The experimental design was a randomized complete block design with three replications in each trail. Four traits were studied i.e. seed cotton yield (K/F), Lint cotton yield (K/F), Seed Index (g) and Micronaire reading. All traits showed significant mean squares for environments, also significant for genotypes x environment interaction for all traits were detected . All traits showed significant mean squares for all genotypes. The two genotypes L2 [G.80 x Australy] x G.83 and L5 [G.83 x (G .80 x G .89 )] x Australy exhibited high seed cotton and lint yield than the other genotypes. The genotype L2 [G.80 x Australy] x G.83 for seed and lint yield, Giza 95 seed index and Giza 90 and L1 ( G.90 x Australy ) for for microniar reading had above average stability. Therefore, these genotypes can be recommended to be released as stable high yielding and fiber quality genotypes and/or be incorporated as breeding stock in any future breeding program aiming for producing stable high yielding with high fiber quality.
