Phenotypic screening during kharif 2015 and evaluation of Sub1 introgressed lines in Ranjit and Bahadur for submergence tolerance was done with the 35 genotypes. Out of 35 genotypes 32 were Sub1 introgressed BC2F3 lines (24 BC2F3 lines of the cross -Ranjit x Swarna-Sub1and 8 BC2F3 lines of the cross -Bahadur x Swarna-Sub1) with three parents . Ranjit, Bahadur, and Swarna-Sub1. The phenotypic screening of genotypes showed that all Sub1 introgressed lines had significantly higher survival rates as compared with the original recipient parents whereas less change in plant height was observed. | Phenotypic screening and evaluation of Sub1 Introgressed lines in popular rice varieties ranjit and bahadur of Assam India
