Analysis related to the alternative growth habit in wheat varieties at the Carillanca Exp. Sta.

Cristian Hewstone M.1

Appearance of first node and heading observations, taken with different sowing dates and years at Carillanca (Temuco) and Quilamapu (Chillán) Experiment Stations ((NIA), in winter, alternative and spring wheats, were used to determine the differences between them and to describe the alternative habit, by means of linear regressions on sowing dates. Climatic variables related with these results are analyzed and the variation produced by change of latitude is studied.
