Root anatomical and morphological basis for drought resistance in tomato (Solanum Iycopersicon)

Abstract

Present investigation was aimed at understanding the role of root anatomical features imparting drought resistance. It was interesting to note that roots of mutant derivative had more number of xylem poles along with increased diameter imparting drought resistance. Cultivated species with lower number of xylem poles and smaller diameter were found to be drought susceptible. Henceforth, in drought resistance breeding, due weightage need to be given on root anatomical and morphological parameters to develop true and stable drought resistant tomato genotypes.
