dc.description.abstractColeoptile length, crown depth, subcrown internode length and emergence rate index (ERI) of ten commonly grown wheat cultivars in the Central and Southern Great Plains of the USA were studied in the controlled environments and in the field under various planting depths and temperature regimes. In the germination chamber tests, there were significant genetic differences in coleoptile length at 15, 20, 25 and 30 C temperatures. Coleoptile length of all cultivars was maximum at 15 and 20 C. Temperature x cultivar interaction was significant, partially due to a significant reduction in coleoptile length at 30 C. In the greenhouse, cultivars and planting depths differed significantly for coleoptile length, ERI, crown depth and subcrown internode length in most cases. Cultivar x depth and cultivar x temperature interactions were highly significant for all the characters studied.
