Biochemical markers for cold tolerance in Boro rice

Abstract

26 genotypes of rice were grown in winter season nursery to study their tolerance ability against low temperature stress at seedling stage and to find out suitable biochemical parameters, which may help in screening for cold tolerance at seedling stage. Out of several biochemical parameters, non- reducing sugar and phenol content were found to be most efficient markers for screening of cold tolerant genotypes at seedling stage as these traits exhibited highly significant correlation with cold tolerance as well as among themselves.
