AN ALTERNATIVE APPROACH TO ANALYSIS OF GENOTYPIC ADAPTATION IN RICE

Published on Oct 06, 2019 03:02 AM

Twelve rice varieties grown under 30 environments were evaluated for their adaptation
through different approaches. Stratification of environments and considering mean
yield of the genotypes in different grades of environment, the metroglyph analysis
was done which showed that five genotypes were agronomically superior with wide
adaptation and one with specific adaptation to favourable environments. This
metroglyph analysis of stratified environmental average is considered to be a simple
method which may be used even in preliminary evaluation of crop genotypes for
their adaptation.
