Differentiation of cytoplasm of Saccharum and Erianthus species by mitochondria! DNA polymorphism

Published on

The sugarcane varieties under cultivation are man-made complex interspecific hybrid derivatives, primarily between Saccharum officinarum L., the 'noble' cane and the wild S. spontaneum L., with the contributions also from S. barberi Jesw., S. sinense Roxb. S. robustum Brandes and Jesweit ex Grassi and the related genera such as Miscanthus Anderss. and Erianthus Michx. [1]. The cytoplasmic diversity in the cultivated sugarcane varieties are very limited, because only a few S. officinarum clones such as Black Cheribon, Vellai, Ashy Mauritius, Bandjermasin Hitam, and Badila were involved as female parents in their ancestry [2]. The enhancement of genetic base of sugarcane is being done by gene introgression from wild related species S. spontaneum and Erianthus arundinaceus (Retz.) Jesweit, which are cross compatible with sugarcane. Attempts are also being made to diversify the cytoplasm base of sugarcane with the related species [3].
