Abstract

Genotype x environmental interactions play a very important role in crop improve- ment programme and much expected genetic advance could be predicted after eliminat- ing all such influences. This gives meaningful and real estimates of genetic advance under selection. This is illustrated with reference to the data on yield in okra con- ducted over two seasons at College of Agriculture. Dharwar. The practical implications of these interactions and genstic parameters have been brought out for considerations and genetic parameters have been brought out for consideration of the plant breeders. It is suggested from the study to increase the number of locations testing rather than increasing the years of testing.
