Features of Pollen fertility Restoration in winter rye F1 heterosis hybrids (Secale cerealE L.)
Abstract
In the article, the basic results of a restoration index studying in F1 heterosis hybrids with the use of different types of cytoplasmatic male sterility (CMS) are stated. Rather the low level of pollen restoration for “Pampa” type CMS at the majority of F1experimental hybrids is established. It is shown that the use of the gene of fertility restoration from the Iranian rye can essentially raise the restoration index, but the effect of the gene is different at the use of various parent ms-forms. Studying of the restoration index in F1 heterosis hybrids on the basis of G-CMS has shown that all inbred-lines used as a male component are reliable restorers irrespective of a female component.
