TO THE QUESTION OF PSEUDO-SELF-COMPATIBILITY OF THE TETRAPLOID WINTER RYE

In Ust-Kamenogorsk and Novosibirsk, the manifestation of pseudo-self-compatibility (PSC) at the zoned sort of tetraploid winter rye Zashchita and allocated from Zashchita so-called “Rodoslovnaya 25”, inclined to rather high PSC, were investigated. The sort in Ust-Kamenogorsk and Novosibirsk had rather low PSC (4,4 and 6,5%). The “Rodoslovnaya 25” remain the tendency to significantly higher level of PSC: in Ust-Kamenogorsk in S 2 ? 11.6, in S 3 ? 21.5 %; in Novosibirsk in S 2 ? 37,1 %. Thus in two points the connection between rather PSC high level and short-stalked, uniformity of plants on culm length remained.
