THE FIRST STEPS OF BREEDING OF MALE STERILE AND MAINTAINING ONION (ALLIUM CEPA L.) LINES FROM THE BELORUSSIAN VARIETYES VETRAS AND SKARB LITVINOV BASED ON N- AND S-CYTOTYPES DETECTION

Abstract

S-cytotype first testcrosses had 90 % of plants with male sterility, more than ST, STN, SN, N-cytotypes found in the Skarb litvinov. With this in mind, the Skarb Litvinov variety open polinated population is good source of male sterile lines.
To create male sterility maintaining line B the self-compatible plants having pure N-cytotype should be selected from population of Vetraz variety. Due to low number (8 %) first inbred families having msmsN or MsmsN testcrosses and selfing can to be carried out manually. Inflorescences were isolated by polyester cages, astringed around with a cotton thread.
