Publication Type: Abstract Only Publication Acceptance Date: 2/15/2016 Publication Date: N/A Citation: N/A Interpretive Summary: none Technical Abstract: Lentil is grown in many parts of the world where the photoperiod and temperature prior to flowering differ dramatically. Cultivars from one region struggle to perform well in other regions due to problems related to phenology. This makes breeders reluctant to use un-adapted material in their crosses with a consequence of loss of genetic variability within their program. To better understand how lentil is adapted to different marco-environments, and to identify markers for genes that control adaptation responses, we grew a diversity panel of 324 accessions for two seasons in nine locations around the world: three each in South Asia, North America, and around the Mediterranean. Data were recorded for phenology and related traits, and environmental data were collected. All accessions matured in the Canadian environment, but only 1/3 reached maturity before the temperatures got too high in the South Asian locations. The South Asian lines typically flowered and matured very quickly in Canada, not leaving enough time to develop much seed. Across the accessions, however, there was a lot of variability in response across the different growing environments. We also genotyped all lines extensively to better understand the underlying genetic variability in these lines. An association mapping study will allow us to identify regions of the genome that are associated with key traits related to adaptation. |
