Vytilla 3 — A new cytoplasmic male sterile source of tropical rice (Oryza sativa L.)
Abstract
Cytoplasm of Vytilla 3, an improved saline tolerant variety of Kerala was identified as a new source for cytoplasmic male sterility in rice (Oryza sativa L.), suitable to warm humid tropical climatic conditions experienced in the rice growing tracts of the world. This is a break through in hybrid rice production in this country. The varieties IR36 and Hraswa (an extra short duration variety of Kerala) are the proposed maintainer lines and the variety Mattatriveni is the proposed restorer line.
