| Abstract | ||
| The Superiority of genotype must be discriminatively through multi-environment trails (MET). This study aimed to evaluation effect of genotype by environment interaction and stability performance for seven cotton genotypes over six environments via AMMI and GGE-biplot methodology (genotype plus genotype by environment). Experiments were conducted using a randomized complete block design, during 2017 and 2018 seasons at six environments. Significantly affected by E, which explain 72.8% of the total variation ( E + G + GE ), 5.77 for G. and 21.44% for GEI. The biplot analysis cleared that two environments, Beni-Souif and EL-Sharkeia with genotypes lines No.1 and 2 as the winning genotypes and the lines No. 4 and 5 as the winning in the two environments EL- Sharkeia and Kafr El-Sheikh. Lines No. 1 and 2 were the most stable the highest yielding and closest to the ideal genotypes also, line No. 4 had average stable with favorable yield, whereas line No. 5 had high average mean, but it more variable in environments. The lines No. 1, 2 and 4 were average stable according to AMMI method commonly, the two lines No. 1 and 2 should be selected as the best and ideal genotypes. Also, the best environments were EL- Sharkeia and Beni-Souif. | ||
