Abstract: | - 1.
Six populations of winter rye were chromosome-doubled in 1951 by means of colchicine. After one generation of multiplication the populations were grown as spaced plants (1954). Records were taken on a number of quantitative characters. Grain yield and number of ears per plant showed very skew distributions, whereas strawlength was approximately normally distributed. Highly significant positive phenotypic correlations were found between grain yield and ear number per plant, and between grain yield per plant and strawlength.
