Development of high yielding genotypes under such conditions require a thorough knowledge of genetic variation and yield contributing characters to exploit complete genetic variability to exercise selection for development of yield contributing traits.
Development of high yielding genotypes under such conditions require a thorough knowledge of genetic variation and yield contributing characters, the observed variability is a combined estimate of genetic and environmental causes whereas genetic variability alone is heritable. Moreover the estimate of genetic variability across the environments with in the conditions, however result in a favorable environment to exploit complete genetic variability to exercise selection for development of yield contributing traits.
