<strong>DRR</strong> Annual Progress Report 2010, Vol.1 – Varietal Improvement<br />

highest yielding check under drought and normal rainfall conditions, IET 20859 and IET 20871<br />

could not establish stable yield advantage over highest yielding check in any state either under<br />

drought or normal rainfall conditions, hence discontinued from further testing.<br />

The entry which IET 20863 showed yield superiority over best check in Jharkhand for all<br />

the three years, hence appears to be promising for the state <strong>of</strong> Jharkhand only in drought affected<br />

locations.<br />

Among the entries tested for 2 nd year viz., IET 21281, IET 21289 and IET 21291, none<br />

could establish required yield advantage over best check neither under drought nor normal rainfall<br />

conditions on overall mean. Whereas in region 3 and region 4 under normal rainfall conditions, IET<br />

21291 and IET 21289 could yield 8.31% and 9.87% higher than the best check, respectively but<br />

failed to establish superiority under drought conditions, hence, none were considered for promoting<br />

to 3 rd year <strong>of</strong> testing.<br />
