Description

Winter rape seeds (Brassica napus L. cv. Jet Neuf) were irradiated twice with gamma rays. In γ1-2 generation (dose 50.0 kR) plants with reduced fertility were selected. Offspring of these plants, in the following generations, were segregated into fertile plants, partly fertile and sterile plants. Analysis of meiosis in PCM revealed presence of a great number of cells (in prophase 1. and metaphase 1.) with crosses, rings and chains of multivalents. It is a proof of vast heterozygous translocation. (author)
