Correlation studies in morphological and biochemical characters in rice under iron toxic field condition

Author(s):

Abstract:
Eleven rice genotypes selected from laboratory screening experiment was grown under iron toxic field condition. Various characters related to iron toxicity tolerance were studied. Association analysis was carried out among the characters root length, total number of roots(20DAT),number of fresh roots(20 DAT), Visual scoring at flowering (0-9), Visual scoring at maturity (0-9), Iron content in root, iron content in 3rd leaf, iron content in oldest fully opened matured leaf, Iron content in grain, iron content in straw, grain yield per plant. Study showed that visual scoring showed positive correlation with iron content in leaf and negative for grain yield per plant. Root characters exhibited a positive correlation with grain yield. Association analysis revealed that iron toxicity tolerance of genotype is a complex character and selection cannot be done based on a single character. Iron content analysis on various genotypes shows the presence of root based and shoot based tolerance mechanisms.
