THE ESTIMATION OF PEAS COLLECTION IN THE ALTAI

The article emphasizes the importance of peas as a source of vegetative protein, and indicates on insufficient areas under peas both in Russia and in the Altai. One of the reasons of reducing its acreage is the high costs on peas planting and protecting from pests, diseases and weeds. Climate changing contributes to rapid development of such harmful diseases as ascohitoz, bacteriosis, fusarium, rust, significant number of weevil, pea aphid and moth mullet. Considering the main directions in pea breeding, it should be emphasized that the Altai Area, with its vast territory and diverse natural and climatic conditions, requires highly productive, well-adapted varieties of different use which are capable to effectively use agro-climatic resources of different zones. All this requires the active study of the source material, the selection of new, economically valuable forms and their introduction into the breeding process. It has been noted that the production requires more advanced varieties, the development of which is impossible without the presence of diverse source material. The purpose of the study was to identify the best productive plants in the pea collection of 2012-2017. The material has been represented by 113 variety samples of domestic and foreign selection. The varieties with best productivity were ‘Mnogoplodny 163’, ‘Rheinperle’, ‘Flagman 12’, ‘806’9, ‘Varyag’, ‘Altaisky Usaty’, ‘Pioner’, ‘LittleMarwel’, ‘Mnogoplodny 27’, ‘Zeleny Tsukat’, ‘Ryadovoy’, ‘576/80’. The best forage productivity was produced by ‘Novosibirets’, ‘Varyag’, ‘Pino’, ‘Zeleny Tsukat’, ‘Mnogoplodny 105’. The most fast-ripening varieties were ‘Rheinperle’ and ‘Pyrama’. The samples ‘Novosibirets’, ‘Varyag’, ‘Pino’ and ‘8067’ were characterized with high plant height. The samples ‘Pyrama’, ‘Flagman 12’, ‘Novosibirets’, ‘Sihirobana-Kinusaja’, the line ‘312’ produced large-sized kernels. The great lodge resistance has been shown by ‘Altaisky Usaty’, ‘Svetozar’, ‘Kamerton’, ‘Flagman 12’.
