Three tall and 33 short bread wheats derived from Norin 10 [Agriculture and Forestry 10], eight short durum wheats and four triticales were examined. Genotypic effects on photosynthetic activity (PA) and leaf permeability (LP) were highly significant. Among the short bread wheats, PA four weeks before anthesis and preanthesis growth rate were positively correlated with mature plant height. PA was also positively correlated with growth rate during grain filling and with yield. Number of days to anthesis positively affected these three traits, probably reflecting an increase in sink size (grains per m2) with later anthesis. Yield was positively correlated with LP, suggesting that the latter should be tested as an early generation selection criterion
