- The object of research were F1 hybrid grains of winter rye resulting from the topcross of 90 yellow-seed inbred lines with the green-seed tester SMH-108. The degree of crossing ability and the effect of xenia on 1000-grain weight were confirmed. In the present investigation quantitative xenia was analysed with regard to the green colour of grain. In the collection of 90 inbred lines of yellow grain differences in% of crossing were ascertained and in 26.7% of the analysed lines a significant quantitative xenia (1000-grain weight) was found. Among the 90 lines as much as 28.9% gave, in conditions of open pollination, from 66 to 85% of hybrid grain. Four lines were selected, which gave a quantitative xenia in 38, 25, 20 and 12% and crossing of 57, 84, 58 and 74%. These lines may be of practical use in producing heterosis hybrids.
