Study of variability in productivity elements of winter triticale collection [Articol]

Abstract

Arid conditions, which are increasingly common in the world, have a negative impact on the development of agricultural crops and pose a great threat to the implementation of potential plant productivity. In this regard, the purpose of this study is to evaluate collection variety samples for economically valuable traits and to select promising genotypes for use in the breeding process. This article presents the results of a study of 36 triticale variety samples of different geographical origins for the main economically valuable traits (plant height, main spike length, number of spikelets per spike, number of grains, grain weight and 1000-grain weight). Analysis of the productivity elements of the studied samples revealed high variability in the number of grains and grain weight per spike, which makes it possible to select valuable genotypes. Promising samples have been identified based on individual productivity traits and their complex for targeted use in selection of parental pairs included in hybridization.
