Studies on the use of induced autopolyploidy in the breeding of red clover. Part 3. Frequency and behaviour of aneuploids in a tetraploid clover ley

, : Studies on the use of induced autopolyploidy in the breeding of red clover. Part 3. Frequency and behaviour of aneuploids in a tetraploid clover ley. Zeitschrift fur Pflanzenzuchtung 71(3): 253-263

The frequency of aneuploids in a tetraploid population, Sv059, was 35%. Of these, a greater percentage had excess chromosomes than were deficient in chromosome number. In a field trial, the aneuploid frequency was the same in the first year and in an intact stand in the third year, but a significant reduction in frequency was found in thinned stands in the second and third years.
