In two previous articles the analysis has chiefly dealt with phenotypic effects in cereal development, centering on the feature of spike fertility conditioned by different climatic treatments. In the present survey a series of generative, semigenerative and vegetative traits have been considered. The experiments have given information on the role of genotype, photoperiod and thermoperiod, as well as of the binary and three‐factor interactions, together with features of replication, on trait development and performance, covering inherent and environmentally conditioned variability. The analytical procedures imply an establishment of synthetic multidimensional variables, with variance deductions of significant effects of diverse genotype and environment factors. Three kinds of materials are involved: (1) the barley variety Bonus, its X‐ray mutant Mari, and their reciprocal monohybrids, (2) Bonus barley and Drabant spring wheat in a mutual comparison of growth and performance, and (3) a climatological study of four (five) barley varieties, two of six‐row type, and two (three) of two‐row type. The plant materials were grown under controlled conditions in four (five) different photoperiods and two (three) thermoperiods.
