Description A largely rainfed crop in India, drought tolerance, particularly
mid- and end-season tolerance, is a key trait in groundnut
varieties. A combination of both empirical and trait-based
approaches was used in breeding programs of ICAR and ICRISAT,
resulting in release of few tolerant varieties that have
superior pod yield under drought stress and/or have enhanced
water-use-efficiency. There is a need to breed varieties with
drought tolerance, disease resistance and quality traits that suit
different production ecologies as well as meet the needs of the
farmers, consumers and industries. ICRISAT has released an
early-maturing (90-95 d) and drought- tolerant variety ICGV
91114 for the drought-prone Ananthapur district of Andhra
Pradesh, India, where about 0.7 m ha area is under groundnut
cultivation and has low (300 mm) and erratic (30-40 rainy
days) rainfall. On-farm studies conducted with ICGV 91114
during 2008-10 showed 30% reduction in yield variability over
the years. Following screening in hot-spots of both rust and LLS
disease during 2014 rainy season, a total of 27 introgression
lines derived from ICGV 91114 were selected and advanced for
evaluation in multi-location trials at six locations in 2015 under
rainfed conditions. Based on the pod yield under rainfed conditions
and disease resistance, three superior introgression lines
(ICGV 14410, ICGV 13189, ICGV 14421) were proposed for the
first-ever NILs trial (near-isogenic lines trial) along with eight
others conducted under All India Coordinated Research Project
on Groundnut (AICRP-G) at national level.
