Grain filling duration as a means for increasing yield in spring wheat

Published on Jan 22, 2021 03:00 AM

Grain filling duration, the period between heading date
and physiological maturity, plays an important role in
determining the final grain yield in spring wheat. The
variability for grain filling duration and selected
agronomic traits was studied in 72 spring wheat
genotypes. There was wide genetic variation in the
genotypes for the traits examined. It was observed that
earlier heading lines tended to have longer grain filling
duration as compared to later heading genotypes.
Genotypes having shorter grain filling duration were
identified for further utilization.The grain filling duration
was significantly correlated with grain yield and its
components, kernels per spike and kernel mass. The
results suggest that increasing grain yield in spring
wheat was possible through breeding for grain filling
parameters.
