Screening of Rice (Oryza sativa L.) Genotypes for salinity at Reproductive Stage

This study highlights the varying degrees of tolerance to salinity among different rice genotypes. It's interesting to note that despite rice being considered moderately sensitive to salinity. The phenotypic response of 20 rice genotypes with salt stress at EC=12dsm-1 was assessed under hydroponic condition at reproductive stage through visual scoring. Five genotypes, viz., MCM103,CSR27,MCM151-3-2-1-1 , MCM208-12-1-1, AC39416A demonstrated tolerant and 12 genotypes MCM 100, MCM109, MCM125 , MCM1471-1-2-1 , IR04A115, MCM153-1-1-1-1, MCM106-2-10-2-2, MCM258-8-2-1-1-1 , MCM148-2-1-1-1 , IR18T1045, IR100120-B-B-B-11 and MCM159-3-1-1-1 considered as moderately tolerant in the face of salt stress.Conversely,3 genotypes like FL478 ,BPT5204 ,PUSA44 showed susceptibility.
