N2  - Groundnut (Arachis hypogaea L.) is the second most
important oilseed in India, which is mainly grown in states like
Gujarat, Andhra Pradesh, Karnataka, Tamil Nadu and
Maharashtra. More than one-third of the soils in India are
calcareous and spread mostly in the low rainfall areas of the
western and central parts of the country where groundnut is a
major crop. As calcareous soils are deficient in available iron
(Fe2+), iron deficiency chlorosis (IDC) is more prevalent in
Saurashtra region of Gujarat, Marathwada region of
Maharashtra, and parts of Rajasthan, Tamil Nadu and
Karnataka causing significant reduction in yield (Singh et al.,
2004). Iron deficiency leads to interveinal chlorosis of younger
leaves, while under severe deficiency they turn into white and
papery and further as brown and necrotic. Genetic variability
for resistance to IDC has been reported earlier in groundnut
(Samdur et al., 2000; Li and Yan-Xi, 2007). Cultivation of IDC
resistant cultivars in calcareous soils is economically feasible
and sustainable approach compared to application of iron
containing fertilizers through soil or foliar spray.
