Characterization of elite lentil genotypes for seed iron and zinc concentration and genotype x environment interaction studies

Published on

Forty-one lentil genotypes were evaluated to analyse
genotype × environment interaction for iron and zinc
concentration in the seeds. The analysis of variance for Fe
and Zn concentration in grain at individual locations
showed highly significant differences between genotypes.
Pooled analysis of variance over locations displayed highly
significant differences between genotypes, locations and
genotype × location interaction. Among 41 genotypes, the
maximum mean seed Fe concentration over the locations
was observed in L4704 (136.91 mg kg–1) while maximum Zn
concentration in grain was observed in VL141 (81.54 mg
kg–1). The highest mean seed Fe and Zn was recorded at
New Delhi (Fe -87.30 mg kg–1 Zn-68.60 mg kg–1). Although
both the micronutrients were influenced by environment,
seed Fe was more sensitive to environmental fluctuations
in comparison to seed Zn concentration. The G × E study
revealed that the genotypes VL 141 was most stable and
adapted to the diverse environmental conditions of North
West Plain Zone for Zn concentration. The genotypes, VL
141 and LH84-8 had high mean value for Fe concentration
with little deviation from regression. AMMI biplot revealed
that for Fe concentration in all the three locations exhibited
equal discriminating power, however, for Zn concentration
Ludhiana was found to be most discriminative. The three
locations exhibited poor correlation between them for both
Fe and Zn concentration in seed. This is the first report on
iron and zinc concentration in lentil from India.
