Seed productivity of pea samples of various origins from the VIR collection in the conditions of Eastern Siberia

Abstract

One of the first stages of classical breeding work is the search for sources to include in subsequent hybridisation, with VIR being the leading supplier of such resources. In the Siberian region, crop samples must be adapted to local adverse environmental conditions while maintaining high seed productivity. It makes the research relevant, aiming to find sources for inclusion in the breeding process. It makes the research suitable, seeking sources for inclusion in the breeding process. The authors studied 120 pea samples from the VIR collection in the conditions of the Krasnoyarsk Forest steppe from 2017 to 2022. Three sets of examples of different origins were learned over three years in different periods: 2017–2019, 2018–2020, and 2020–2022, with the number of samples examined in these periods being 35, 42, and 43, respectively. The authors evaluated seed mass per plant, the number of seeds per plant, and pod wrinkling to analyse seed productivity. The average hands of "seed mass per plant" for all sets (in all study periods) were below the standard: the standard was 5.01, 6.10, and 7.88 g, while the average value of seed mass per plant was 3.90, 4.34, and 5.49 g, with a 95% confidence level of 0.41, 0.45, and 0.35, respectively. Among the studied samples from the VIR collection in the region, when grouping pieces by origin, representatives from Ukrainian selection and the Voronezh region stood out in terms of the "seed mass per plant" indicator. However, some samples exhibited better hands in samples that showed negative results. Considering seed productivity among the studied pieces from the VIR collection, along with their technological characteristics, it is recommended to use the samples Glance (k-9636) from Ukraine and SH-95-66 (k-10010) from Bulgaria as sources for breeding work in the conditions of Eastern Siberia.
