	<span style="line-height:1.5;">Cotton yield and fibre
quality parameters are dependent on the environment in which the crop is grown.
A major challenge in crop genotype recommendations is genotype กม environment
interaction. The identification of cultivars with
high adaptability and stability is one of the best ways to address this
challenge. Genotype กม Environmental
interaction on </span><i style="line-height:1.5;">Gosypium hirsutum</i><span style="line-height:1.5;"> was
investigated. Ten genotypes were plant</span><span style="line-height:1.5;">ed in a randomised complete block
design with three replications. Collected data were subjected to Analysis of
Variance (ANOVA) with genotype and location
as factors. Additive Main Effect and Multiplicative Interaction model which combines standard analysis of
variance with principal component
analysis was used to investigate the genotype main effects, environment
main effects and the GE interactions. Significant genotype กม environment interactions existed for
lint yield, boll weights, staple length, and fuzzy seed grade. There were no significant cultivar กม site interactions on
total seed cotton yield. Cotton
cultivars respond differently to different growing conditions implying that,
correct choice of varieties by growers for specific production conditions, must be a must to avoid losses
due to genotype กม environment
interactions.</span>
