Comparative success with respect to hybridization amongst triticale and wheat gene pools in different climate regimes was studied in this investigation. For this, 10 diverse genotypes of triticale were crossed amongst themselves and also with 10 different genotypes of wheat in the sub humid-mid-hili (short-day) and dry temperate (long day) conditions at Palampur and Kukumserl, respectively. The success was better in the crosses amongst the constituents of primary gene pools et both the locations. Crosses among the different genotypes of triticale recorded a success of 29.91 and 47.23 per cent, respectively at Palampur and Kukumseri in comparison to 17.05 and 32.86 per cent in triticale × wheat crosses at both the locations. However, seed set was more at Kukumseri with long day conditions in both triticale × wheat and triticale × triticale crosses in comparison to short day conditions at Palampur. Long photoperiods, static temperature regimes and less intermittent rainfall promoted seed set in both the types of crosses under long day conditions at Kukumseri.
