Abstract

Identification of high yielding genotype at early stages of varietal development may be realized through evaluation of the genetic system of dry matter accumulation. Usually harvest index (HI) is used as a criterion for this purpose. It was found that harvest index is not applicable in wheat as the relationship between harvest index and plant productivity was linear and that was nonlinear between the genetic system of dry matter accumulation and plant productivity.
