Autonomous apomixis at plants of stem Morus

Abstract

The purpose. To conduct screening of grades from collection gene pool of mulberry tree of grades Marus alba L. and Morus bombycis K., and a hybrid on ability to autonomous apomixis, and also to receive experi­mentally apomictic plants of mulberry tree. Methods. They placed insulators on branches of female plants of mulberry tree before opening of flower buds to imi­tate unfavorable natural settings of pollination. Under these conditions ability of grades to produce apomictic seeds was estimated. Results. Ability of mulberry tree to form apomlctic seeds of autonomous type at grades and hybrid of mulberry tree is proved. From seeds they cultivated apomictic plants. Conclusions. For the first time it is proved experimentally ability of some grades and hybrids of mulberry tree to form viable apomictic seeds.
