Abstract
Goal. The study objective was to evaluate soft-seeded accessions for valuable components of spike performance, confectionery properties and to form a trait collection by grain hardness and confectionery properties.
Results
and Discussion. To form a
trait collection by grain hardness, the test material was first differentiated
by its texture. The best (in terms of yield capacity and a set of valuable
economic features) accessions of the test material belonged mainly to bread
wheat. However, analyzing eco-geographical diversity of the test material, we
identified a number of soft-seeded
forms with valuable levels expression of some components of spike performance.
To improve the complex value of confectionery forms and to enrich the soft
winter wheat collection with new, more valuable biscuit accessions, we crossed soft-seeded accessions with accessions with harder
grain. The soft-seeded lines obtained were also included in the trait winter
bread wheat collection. Starting material with a set of valuable economic
features is of the highest breeding value. Trait collections offer more
opportunities to create new, more valuable in terms of a set of traits
material. In 2011-2013, studying soft-seeded
winter bread wheat, we identified sources with high levels of expression of
spike performance components: the spikelet number per spike – VS 2367-11 (UKR); Astella,
Malyska, Zerda (SVK); the grain number per spike – VS 2367-11, S 1662-12, VS
2653-11 (UKR); Kondor, Astella, Malyska, Zerda, Arida (SVK); Goncha (TKM); high
grain weight per spike – S 1662-12, VS 2367-
Conclusions. The staring material tested in 2010-2013 became a basis for the formation of the trait collection of winter bread wheat by grain hardness and confectionary properties. Investigating spike performance components and confectionery properties, we expanded and greatly enriched the diversity of the above-mentioned collection. The collection includes 69 accessions that are differentiated by 27 traits and 108 levels of their expression (Certificate No 235 dated 12.02.2016). The collection accessions come from 15 countries. It is a valuable starting material for the creation of new, high-yielding soft-seeded accessions with a set of valuable economic parameters. The genetic diversity of reference accessions of various levels of expression of these traits allowed identifying differentiators that are valuable for work both with both starting and with breeding material.
