[Improvement of a series of agriculturally valuable traits by pollen selection in Linum usitatissimum L].
Influence of selection of F1 high temperature tolerant pollen on the structure of BC1 segregating populations was studied for a number of agronomically important traits in oil flax. It was found that heat treatment of heterogeneous pollen population considerably changed genetic composition of plant population not only for tolerance to drought but for duration of seedling emergence--flowering period and quantity and inclination angle of side shoots as well. It is supposed that genes which confer these traits are at least partially linked to the genes responsible for pollen sensitivity to high temperature.
