Abstract This study aimed to characterize wheat cultivars for their chilling requirements for differentiation and their relationship to flowering time, to establish a dual purpose ideotype. Seeds of eight genotypes (cultivars and advanced lines) of bread wheat were exposed to constant temperature (4 °C) in germination chambers for 8, 6, 4 and 2 weeks. A control treatment was kept at room temperature. Four replicates of each treatment were placed in the greenhouse in 250 cc pots containing 4 seedlings each, with irrigation and natural photoperiod, following a randomized complete block design. The greenhouse temperature was constant… More >
