Relationship between the stem color and the ear spines presense with economically valuable traits of bread winter wheat

Abstract

Determination of the breeding value of the presence or absence of ear spines and anthocyanin stem color in bread winter wheat plants in the steppes of the Black Sea coast of Ukraine. Methods. Growing plants in the field. Phenological observations, weight of 1000 grains, analysis of variance and statistical significantly of the difference by t - criterion in pairwise comparison. Results. Groups of lines with the presence or absence of ear spines and with anthocyanin or green color, as well as with different combinations of both phenotypic traits did not differ significantly in economically valuable traits, with one exception. Plants with anthocyanin-colored stems were, on average, statistical significantly five centimeters taller than those with green color. Among the lines that exceeded the standard varieties Antonivka and Kuialnyk, in terms of yield, there are lines of all possible combinations of stem color and the presence or absence of spines. Conclusions. The phenotypic differences of recombinant lines in stem color (anthocyanin or green) or the presence or absence of spines, as well as their various combinations, are not significantly related to differences in genotypes before earing period, plant height, 1000 grain weight and grain yield.
