Abstract

Winged bean [Psophocarpus tetragonolobus (L.) DC] is a protein rich, underexploited leguminous vegetable of the tropics. It grows abundantly in hot and humid environments. The present investigation applied AMMI and GGE biplot techniques to study the patterns of GEI in 05 winged bean genotypes, to find high yielding and most stable genotype(s) suited to Chhattisgarh state of India.

An experiment was carried out to ascertain the gene * environment interaction (GEI), yield stability and adaptability of 05 winged bean (Psophocarpus tetragonolobus L.) genotypes in Chhattisgarh India by using AMMI and GGE biplot models.

First and second component of AMMI model explained more than 84.10% of GEI variation. Genotype ‘AKWB-1’ exhibited maximum trait value with specific adaptation while genotypes ‘RMDWB-1’ and ‘Ambika 11-3’ showed general adoptability. GGE biplot model explained that genotypes ‘RMDWB-1’ and ‘AKWB-1’ were the best performers in all the environments excluding E4, while ‘Ambika 11-3’ was the best performer at location E4 regarding the graphical analysis models of AMMI and GGE biplot. Winged bean genotype ‘AKWB-1’ was the most stable genotype in all the test environment in terms of mean yield and it would be recommended for commercial cultivation in Chhattisgarh state. Other high yielding and stable genotypes i.e., RMDWB-1 and Ambika 11-3 can also be used as parents in winged bean improvement programs.
