Abstract

Aim. To identify sources of economically valuable traits for further breeding based on results of field studies of winter triticale accessions of different eco-geographical origins.

Results and Discussion. In 2016-2020, Volyn State Agricultural Experimental Station of the Institute of Agriculture of the Carpathian Region assessed 78 collection winter triticale accessions from Ukraine, Belarus, Russia, Poland and other countries for yield capacity and parameters of environmental plasticity and stability. The study was carried out by the Laboratory of Plant Production and Breeding in temporary experiments of the first breeding crop rotation on the soddy podzolic sandy loam soil. An overview of the current state and results of experimental studies of the genetic potential and economic use of triticale are presented. Numerous data from the global science and practice indicate prospects for expanding the production and use of triticale grain as a new valuable crop to meet the food and feed needs.

Conclusions. The selected accessions were highly adaptable in the Western Woodlands of Ukraine. As a result of trials, 6 collection accessions were identified to create high-yielding winter triticale cultivars: Remiko; Vyato, Priazov; Prometey; Tymofii, Molfar. A winter triticale accession, Shalanda, can be a source of high winter hardiness, high plant density, high resistance to the pathogen of snow mold, and high performance. To create breeding materials with large kernels, cv. Shalanda and Molfar; Remiko, Fredro, and Maestro; Kvazar, Mamuchar, Kapral, Argo, Vyato, Sergey, and Khleborob; Pika; NTH 1933 with thousand kernel weight of 46.3-55.0 g can be used. To increase resistance to leaf blotch, one can use the following collection accessions: Donets and Rarytet; Trapero; Kapral and Priazov. Cv. Rarytet can be considered as the check cultivar for the woodlands zone: the score of resistance to this disease was 9 points. Cv. Tit is recommended as a source of early ripening in the woodlands zone (262 days).
