        <dc:description>Iron deficiency is an important abiotic constraint reducing&#13;
the growth and yield of groundnut especially under&#13;
calcareous soils. Foliar application of Fe-chelates can&#13;
overcome iron deficiency but it is not economical.&#13;
Evaluation of 318 recombinant inbred lines (RILs) along&#13;
with parents for iron deficiency chlorosis (IDC) and&#13;
productivity traits under iron deficient soils over three years&#13;
indicated significant genotypic and genotypic x&#13;
environment interaction (GE) component for both IDC and&#13;
productivity traits. Among the RILs, range of variation was&#13;
higher than that of the parents for visual chlorotic rating&#13;
(VCR), SPAD chlorophyll meter reading (SCMR) and&#13;
productivity parameters across three years indicated the&#13;
presence of transgressive segregants. VCR had higher&#13;
phenotypic and genotypic, variances, heritability and&#13;
genetic advance as per cent of mean (GAM) in all the three&#13;
years as compared to SCMR. Among productivity traits,&#13;
pod yield (g plant–1) had higher PCV and GCV compared to&#13;
shelling per cent and 100 seed weight. Significant negative&#13;
correlation between VCR and pod yield per plant indicated&#13;
effect of IDC on productivity in RILs. Nine lines were&#13;
superior for both IDC tolerance and productivity traits. This&#13;
extensive phenotyping of RIL population for IDC tolerance&#13;
under iron deficient conditions can be used for&#13;
identification of genomic regions associated with IDC&#13;
tolerance by genotyping of this RIL population.</dc:description>
