Abstract:

The purpose of the research was to expand the genetic diversity of winter triticale under intraspecific and remote hybridization and to obtain new valuable forms for their involvement in the breeding process of creating high-yielding crop varieties. For this purpose interspecific and remote hybridization of different species of wheat, rye, triticale, Elimus arenarius L. and evaluation of obtained hybrids were carried out from 2013 to 2020. According to the results of our research it is proved that the species Triticum spelta L. and Triticum petropavlovskyi Udacz. had dominant genes of incompatibility with rye. Crossing Triticum compactum Host. and Triticum sphaerococcum Perciv. species with rye allowed obtaining a higher level of seed setting, but the grain obtained with the participation of Triticum sphaerococcum Perciv. species was not viable. Compatibility of triticale with spelt and Elimus arenarius L. was low. The level of seed formation in F1 hybrids under artificial pollination was higher than under spontaneous pollination. Seed germination obtained from pollination of F1 hybrids by fertile forms of triticale – was low. It was found that hybridization of three-species triticale with spelt had a positive effect on grain quality indicators in the offspring. Crossing triticale with Elimus arenarius L. led to ear elongation, but caused a significant reduction in all indicators of grain quality in the offspring. As a result of remote hybridization of three-species triticale and spelt wheat, winter triticale varieties Navarra and Strateh were created and included in the State register of plant varieties suitable for distribution in Ukraine since 2018.

Abstract:

The aim of our research was to create, analyzes, and systematise wheat collection samples for the selection of valuable initial forms, to involve them in breeding process, and to create new productive cultivars. For this purpose the hybridisation of soft and spelt wheat was carried out, along with an evaluation of the hybrids that were obtained, between 2006 and 2018 (F5–F10). A collection of wheat samples, containing more than a thousand numbered items, was formed from the obtained diversity of samples. The economically-valuable and morphological characteristics of newly-developed materials were analysed. According to the results of our research, we selected forms of spelt, soft wheat, and speltoid samples which have high levels of productivity and high gluten and protein contents in grains.
Spelt wheat sample 1817 contains 45.2% gluten, 22.3% protein, and has a yield capacity of 6.55 t ha-1. Soft wheat sample 1689 has 32.4% gluten, 15.8% protein, and a yield capacity of 7.19 t ha-1. These samples were submitted for state scientific and technical expert evaluation in 2018. The created varieties of European spelt wheat and Artemisia soft wheat were included in the ‘State Register of Plant Varieties Suitable for Distribution in Ukraine’.
The varieties, Artaniia and Artaplot, were submitted for state scientific and technical expert evaluation.
