Vernalization insensitivity is a key feature of domesticated chickpea, and its genetic basis is not well understood. We studied vernalization response among hybrid progeny derived from two domesticated × wild crosses. The wild parents are vernalization-sensitive, late-flowering genotypes while both domesticated parents are vernalization insensitive. Parental lines and hybrid progeny were tested with (28 days at 4°C) and without vernalization (control). The difference in mean days to flower (DTF) between control and vernalization treatments was used to assess the flowering vernalization response. A wide range of DTF values was observed among the hybrid progeny. Strong genotype by environment interaction effect on DTF was observed for the parental accessions and hybrid progeny. We used the DTF values to select vernalization responsive and non-responsive progeny lines. However, the genotype × environment interaction strongly interfered with our selection. Chickpea breeders interested in using the wild progenitor as a donor of exotic traits should be aware of the possibility of introducing vernalization response alleles that may alter the phenology of their breeding materials in an unpredictable manner. © 2016 Blackwell Verlag GmbH.
