The results of study of microstylous examples of buckwheat in Krasnoyarsk forest-steppe

In the conditions of Krasnoyarsk forest-steppe F.E. Zamyatkin created in 2010 macro- and microstylous forms of buckwheat. Macrostylous examples are characterized self-compatibility, but microstylous examples are mainly used as pollinizers during creating of heterotic hybrids. The article shows the results of study of 29 examples of microstylous buckwheat, which was carried out during 2011-2014 in Minderlinskoe farm (Borsk) of Krasnoyarsk region. The evaluation of the examples was made on productivity, the amount of blossom clusters on one plant, the amount of flowers and foetus in a blossom cluster and on a plant, the weight of foetus from one plant and the weight of 1000 foetuses, the persistence to diseases affection and vermin damages. All of the examples outnumber the average productivity of buckwheat in Krasnoyarsk region. The amplitude of its variability made up from 97,7 (21st line) to 160,2 (31st line) g/m2. Microstylous forms of buckwheat with greater productivity was selected: 31st, 24th, 3rd, 2nd, 26th lines etc. The examples of microstylous buckwheat being studied were characterized with greater weight of 1000 foetuses. It varied from 32,79 (21st line) to 39,20 (25th line) gr. Among studied microstylous forms of buckwheat there are interesting for selection examples by its productivity, weight of foetus from one plant (31st, 24th, 2nd, 3rd lines), by the realization of the amount of flowers into corns and showing more productivity (2nd, 31st, 3rd, 26th, 9th lines), by the amount of flowers from 37 to 50 on one plant, by the resistance to lodging. They can be used as the starting material for creating new hybrids with high productivity.
