MTU 1223 (Varsha), a high yielding, non-lodging rice variety released for Rainfed shallow lowland ecology of Odisha and Bihar

Abstract

A high yielding, non lodging rice variety MTU 1223 (IET 25856) was developed from the cross between a high yielding low grain shattering pre release culture MTU 1081 and high yielding long duration variety MTU 1064 through pedigree method of breeding from 2007-2010. In station yield trials conducted at RARS, Maruteru between 2011-2013, it was recorded 27.4% higher grain yield over the national check MTU 7029. In multilocation testing pooled data over seven locations for two years indicated that MTU 1223 has recorded 15.5% yield advantage over the common check variety MTU 7029 (Swarna). In All India Coordinated trials, over all locations, it has recorded 11.59%, 7.99%, 9.27% and 7.13% higher yield than the National, Zonal, hybrid and Local checks respectively. In zone III (Eastern) it has shown superior performance over national, zonal, hybrid and local checks with 16.51%, 12.67%, 22.11% and 11.72% respectively. It was released as straight variety for rainfed shallow lowland ecology of Odisha and Bihar states in 54th Central Varietal Identification Committee meeting in 2019.
