Resumo: Apomixis maintains heterosis and avoids transmission of systemic pathogens which accompany vegetative propagation of cassava. An embryonic study of cleared ovules of two cassava clones in toto showed them to be of aposporic nature. Cytogenetic analysis of the two clones revealed an aneuploid structure (2n + 1) in apomictic individuals, whereas it was 2n in the sexually reproduced plants.

Um estudo embriônico de ovos clareados de dois clones de mandioca in toto mostrou que eles são de natureza apospórica. A análise citogenética dos 2 clones revelou uma estrutura aneuploide (2n + 1) em indivíduos apomíticos, ao passo que era 2n em plantas reproduzidas sexualmente.Em processamentoSociedade Brasileira de Genética2017-12-07T04:28:35Z2017-12-07T04:28:35Z1998info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfGenet.
