Abstract

Genetic peculiarities of waxy barley breeding were investigated at the Plant Production Institute nd. a V. Ya. Yuryev of NAAS for the period of 2005-2013.

Purpose. Study of genetic peculiarities and efficiency of creation of forms with a high amylopectin content in starch.

Material and Methods. In 2007-2009 breeding and genetic features five waxu forms and eight samples of spring barley with typical amylopectin content in starch were studied. Biochemical analyses of grain, structural analysis of plant productivity, genetic analysis by components of the genetic variance, combining ability and heritability of quantitative traits in F1 in diallel cross system were conducted. In 2005-2013 the efficiency of waxy barley breeding via hybridization followed by selection and variety testing was studied.

Results and Discussion. Biochemical and morpho-biological peculiarities by productivity elements of 13 spring barley samples and varieties with different fractional starch composition as well as the variability, correlation, genetic variance, general and specific combining ability, heritability in broad and narrow sense, predominance of additive and non-additive effects of genes of quantitative morphological features and amylopectin content in starch were established. The efficiency of creating valuable lines of spring barley with a high amylopectin content in starch was demonstrated.

Conclusions. The work is of theoretical and practical importance, since breeding and genetic peculiarities by the level of plant productivity structural elements, genetic variance components and heritability of quantitative morphological features as well as amylopectin content in starch in spring barley forms with different fractional composition were established. New waxy lines of spring barley with a set of valuable economic features, which will be used as a source material in barley breeding for high amylopectin content in starch were created.
