Abstract
Genotype has a large influence on the development pattern of wheat, largely due to the response to vernalisation and photoperiod. There is a general belief that development and growth are uncoupled, however there are some reports that early maturing crops grow faster than late maturing crops. A field experiment was conducted in 2011 at Wagga Wagga, southern New South Wales to explore differences in dry matter production of 12 wheat genotypes with known vernalisation and photoperiod genes. Results indicate an association between developmental rate and biomass accumulation, showing later flowering genotypes grew slowly, whilst earlier flowering genotypes showed significant variation in biomass production. Further analysis of the data using genetic characterisation for Vrn-A1, Vrn-B1, Vrn-D1 and Ppd-D1 suggest a possible interaction between this developmental rate-biomass association and vernalisation responsiveness
