INDUCED VARIABILITY FOR FLOWERING, SEED WEIGHT AND OIL CONTENT IN PARENTAL LINES OF SUNFLOWER HYBRID BSH-l
Main Article Content
Abstract
Chemical and physical mutagens were employed in parental lines of sunftower hybrid BSH·l to bring about synchronous nowering, to improve test weight and on content. The nlutagenic treatments significantly enlarged variability for days to Dowering, test weJabt, and oil content in M2 and M3 generations or the parental Unes 11A·234 and RIIA·274. Early and late Dowering mutants were isolated in these lines. In all mutagenic treatments, the mean test weight shifted in positive direction. The chemical EMS was more ertective than gamma rays in creating a wider J'llJlande for test weight. The variability aenerated ror 00 content in the parental Unes provided scope for selection of high-oO mutants. The utOity of the improved Unes isolated hi breedlna has been diseussed.
