EFFECT OF CHEMICAL GAMETOCIDES ON POLLEN STERILITY AND SEED SET IN RICE (ORYZA SATIVA L.)

Published on Oct 06, 2019 03:08 AM

Of the three chemical gametocides tested on four genotypes of rice, ethrel and sodium
methyl arsenate were found to induce maximum pollen sterility in all the genotypes.
Phytotoxic effects were also produced by ethrel to a certain extent in all the genotypes,
especially in IR-57311-95-2-3, like reduced panicle length and spikelet size. The genotypes
IR-n and Swarna recorded minimum seed set under selfing.

Keywords: Chemical gametocides, pollen sterility. rice, selfing, open pollination.
