Breeding possibilities of creation varieties and forms of blackcurrant for machine harvesting

Abstract

The results of the studies of 150 recurrent parents of blackcurrant according to the main features suitability to the mechanized harvesting under the conditions of the Bryansk region (2009-2015) are presented. 3100 seedlings, which have been derived from controlled crossing, inbreeding and self-pollination were studied. For the further breeding sources of the separate agronomic characters, which define the suitability to mechanized harvest, are chosen. The best combinations of hybridization with a high density of berries (>7 H) are established: Kipiana x Glarioza, Debryansk x Selechenskaya 2, Nara x Selechenskaya 2, Istok x Tamerlan, 7-1-157 x Litvinovskaya, Trilena x Litvinovskaya, Barmaley x Debryansk, Yadryonaya x Istok, Debryansk x Dar Smolyaninova, Orlovskaya serenade x Mriya. The varieties and the selective forms, which meet the requirements to a combine harvest on a range of indicators, are chosen. These varieties are Bagira, Kipiana, Partizanka Bryanskaya, Miph, Kudesnik, Selechenskaya 2, Strelets, Sudarushka, Podarok veterans, Tamerlan, Debryansk and selections 33-27-1, 1-5-2, 18-18-6/05, 4-5-2, 73-03-2, 5-66-5.
