Flowering time is a key factor in determining the adaptation of crops to diverse environments. Temperature and photoperiod are the two major environmental variables that affect the length of the period between sowing and flowering and the rate of plant development. The objectives of this research were to examine the days to flowering of selected chickpea (Cicer arietinum L.) accessions grown in a range of thermal regimes combined with either long or short days and to examine the interaction between photoperiod and day and night temperatures on flowering response. Eight chickpea accessions representative of different photoperiod sensitivity responses were included, that is, day‐neutral (ICCV 96029 and FLIP‐98‐142C), intermediate (ICC 8621, ICC 8855, ICC 15294, and ILC 1687), and highly sensitive (‘CDC Frontier’ and ‘CDC Corinne’). Significant effects of accession, temperature, photoperiod, and their interaction were observed for days to flower. Under long photoperiod combined with the higher temperature regime, earliest flowering was observed in day‐neutral accessions followed by intermediate accessions, then photoperiod‐sensitive accessions, which flowered, on average, in 20, 23, and 41 d, respectively. For the two day‐neutral accessions, the difference in the number of days to flower under 16 h photoperiod combined with the temperature regimes of 24 and 16°C and 20 and 12°C (day vs. night) was not significant. Regression analysis revealed that days to flower of the day‐neutral, intermediate, and photoperiod‐sensitive accessions was a linear function of temperature (R² = 0.88–0.99) within the photoperiod.
