germplasm development and field experiments.
N2  - To develop genetic improvement strategies to modulate raffinose family oligosaccharides (RFO) concentration in
chickpea (Cicer arietinum L.) seeds, RFO and their precursor concentrations were analyzed in 171 chickpea genotypes from
diverse geographical origins. The genotypes were grown in replicated trials over two years in the field (Patancheru, India) and in
the greenhouse (Saskatoon, Canada). Analysis of variance revealed a significant impact of genotype, environment, and their
interaction on RFO concentration in chickpea seeds. Total RFO concentration ranged from 1.58 to 5.31 mmol/100 g and from
2.11 to 5.83 mmol/100 g in desi and kabuli genotypes, respectively. Sucrose (0.60?3.59 g/100 g) and stachyose (0.18?2.38 g/
100 g) were distinguished as the major soluble sugar and RFO, respectively. Correlation analysis revealed a significant positive
correlation between substrate and product concentration in RFO biosynthesis. In chickpea seeds, raffinose, stachyose, and
verbascose showed a moderate broad sense heritability (0.25?0.56), suggesting the use of a multilocation trials based approach in
chickpea seed quality improvement programs.
