Description Three F2 populations derived from crosses between
cultivars with green and yellow cotyledon colors were used to identify quantitative trait loci (QTLs) associated with carotenoid components in chickpea (Cicer arietinum L.) seeds developed by the Crop Development Centre (CDC). Carotenoids including violaxanthin, lutein, zeaxanthin, b-cryptoxanthin, and b-carotene were assessed in the F2:3 seeds via high-performance liquid chromatography (HPLC). In the ‘CDC Jade’ × ‘CDC Frontier’ population, 1068 bin markers derived from the 50K Axiom CicerSNP array were mapped onto eight linkage groups (LGs). Eight QTLs, including two each for b-carotene and zeaxanthin and
one each for total carotenoids, b-cryptoxanthin, b-carotene, and violaxanthin were identified in this population. In the ‘CDC Cory’ × ‘CDC Jade’ population, 694 bin markers were mapped onto eight LGs and one partial LG. Quantitative trait loci for b-cryptoxanthin, b-carotene, violaxanthin, lutein, and total carotenoids were
identified on LG8. A map with eight LGs was developed from 581 bin markers in the third population derived from the ‘ICC4475’ × ‘CDC Jade’ cross. One QTL for b-carotene and four QTLs, one each for b-cryptoxanthin, b-carotene, lutein, and total carotenoids, were identified in this population. The highest phenotypic variation explained by the QTLs was for b-carotene, which ranged from 58
to 70% in all three populations. A major gene for cotyledon color was mapped on LG8 in each population. A significant positive correlation between cotyledon color and carotenoid concentration was observed. Potential candidate genes associated with carotenoid components were obtained and their locations on the chickpea genome are presented.
