Evaluation of altered biomass mutant contributing increased grain yield in rice (Oryza sativa L.)
Yield improvement through crop breeding is a constant process to meet increasing yield demand in context of decreasing cultivable land and erratic climatic conditions. Breeding for yield improvement can be achieved through altering plant type. Improving plant biomass can pave way for improving grain yield as grain yield is product of biomass and harvest index. EMS induced mutants serve as a source for creating novel variations for altering plant type. In this view, EMS mutant of Nagina 22 was identified with altered biomass and grain yield. A mapping population of N22 x N22-CC-M4-HT-1333 was studied in F2 and F3 for traits contributing for altered biomass and grain yield. The correlation analysis in F2 and F3 showed that dry matter produced was significantly correlated with grain yield showing the increase in grain yield of the mutant was contributed by dry biomass. This mutant is potential for unraveling the novel ways to improve grain yield and further functional genomics studies.
