dc.description.abstractStability of coconut yield of different varieties in divergentjagro-climatic conditions helps to boost the productivity over a range of environment. The average annual nut yield of six varieties at three locations under the All India Coordinated Research Project on Palms centers viz., Ambajipeta (Andhra Pradesh), Ratnagiri (Maharashtra) and Veppankulam (Tamil Nadu) was analysed for G x E interaction. Seven years yield data between 1992-93 and 1999-2000 was analysed for this study. Eberhart and Russels model and Perkins and Jinks method was used to analyse the data and interpret the results. Laccadive Ordinary had shown maximum yield (105.08 nuts/palm/year) with high variance (2225.50). It could perform well in input Intensive cultures. Fiji has shown good yield (88.72 nuts/palm/year) with (bi=0.77) good stable performance. Andaman Ordinary has recorded low (67.70 nuts/palm/year) but steady (bi=1.05) yields. Hence, they could be useful In input deficient situation. Cochin China was found to be a non-performer. All the varieties were tested with good input management.Their interaction with environment has brought out the hidden genetic potential.en_US
