The heteroallicity instead of heterozygosity in haploids of sugar beet Beta vulgaris L

The view on the nature of the polymorphism found earlier in the haploid lines-regenerantes of sugar beet is revised in the article. The presence of isoenzyme spectra, similar to heterozygous ones, in haploid lines-regenerantes leads to the conclusion that chromosomes in these lines are polytene. The influence of gamete chromosomes polyteny on the variability of the progeny is discussed
