Assessment of Stability for Seed Cotton Yield of Cotton Genotypes Across Different Environmental Conditions of Sindh Province

C is developed in tropical and sub-tropical agro-ecological zones. Rapidly changing and unpredictable climatic conditions demand to identify and introduce more stable cotton genotypes with specific adaptation to specific environments (Iqbal et al., 2018). It is essential to evaluate adaptation and yield stability of promising genotypes across environments. The yield potential of a genotype is the outcome of its interface with the presented environment. The strong effects of ecological factors throughout different phases of crop development, hence genotypes vary broadly in their response to climate (Sial et al., 2000; Bull et al., 1992). Study was carried out with a view to find out the effect of G×E interaction on the yields of new cotton genotypes to identify the firmest and modified genotypes. Sustainable yield requires stable cultivars. Plant breeding is essential phase to recognize firm and extra adjustable strains/genotypes. The learning of stability in cotton is indispensable component of plant breeding earlier to the launch of latest crop variety, generally difference of sites and years are important for sufficient estimates regarding genotypes.
