DRR Annual Progress Report 2010, Vol.1 – Varietal Improvement
Considering the yield performance of entries under drought affected locations, normal
rainfall locations, drought tolerance under rainout shelter none of the entries could qualify
for promotion to advance trial.
However, IET 22034 based on its on par performance with regional check – Vandana
under rainout shelter conditions with drought SES score of 3 may be repeated in IVT-VE-DS.
