HARVEST INDEX AND GRAIN SINK SIZE IN WHEAT

Published on

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.
