Open publisher page 19 citations

Abstract

Gamma ray seed treatment (10, 20 and 30 kR doses) of two cultivars, namely, MPRI-7 and Lanjhi was found to affect pollen and spikelet fertility in M1 generation at higher dose. Chlorophyll and morphological mutations having wider spectrum were also obsrved in M2 generation.
