dc.description.abstractToday, a significant part of the zoned varieties of buckwheat (Fagopyrum esculentum Moench.) are included in the national collection and are constantly monitored for a complex of economically and breeding-important traits. The purpose of the study is to investigate the variability and interrelationships of seed productivity indicators in samples of the national collection of buckwheat in terms of productivity and precocity. The research material was 232 samples of the national collection of buckwheat in Ukraine. The research was conducted during 2007–2024 in the conditions of the Forest-Steppe of Ukraine (Ustymivsk Plant Research Station of the V.Ya. Yuryev Institute of Plant Production). According to the results of the research, the selected samples of buckwheat showed a yield level of more than 380 g m-2, plant and inflorescence productivity - more than 2.0 g and 0.05 g, respectively, and a weight of 1,000 grains of more than 22 g. Valuable sources of early maturity with a vegetation period of up to 72 days inclusive were identified. A high level of variation of the studied traits was established, in particular: yield, plant productivity, inflorescence productivity, lower branch attachment height, lower inflorescence attachment height (V = 23.4–50.0%). The weight of 1,000 grains, plant height, and the duration of the vegetation period had a low coefficient of variation (V = 23.4%), which indicated a stable manifestation of these traits. A strong relationship was noted between the height of the lower branch attachment and the height of the lower inflorescence attachment (r = 0.75), yield and plant productivity (r = 0.85). Correlations of medium strength were established between plant height and the duration of the growing season (r = 0.41), yield and inflorescence productivity (r = 0.64). Valuable sources of productivity and precocity were identified among the samples of the national collection of edible buckwheat. Highly productive samples of edible buckwheat were noted - P-470 and KDS-20-23 (in terms of yield, plant and inflorescence productivity); Yuvileyna 100, Yaroslavna and SYN 3/02 (in terms of yield, plant productivity and 1,000-grain weight). Samples of edible buckwheat P-370, P-396 and Sumchanka were identified for precocity.eng
