Screening of Salt-Tolerant Rice Landraces by Seedling Stage Phenotyping and Dissecting Biochemical Determinants of Tolerance Mechanism

Popis výsledku v původním jazyce

Genetic diversity is a useful resource for crop improvement. In this study, a total of 28 rice genotypes were screened to isolate potential salt-tolerant genotypes at the seedling stage using hydroponic system. Different morpho-physiological indicators were used to classify tolerant and susceptible genotypes and biochemical determinants were dissected to clarify the underlying tolerance mechanism. Rice seedling were treated with two salinity levels EC-1,1 dSm-1control and EC-7 dSm-1 for 18 days. Salt stress resulted in significant decrease of growth and physiological traits in all genotypes, however, the lowest reduction was observed in some salt-tolerant genotypes namelyGhunsi, Nonabokra, Hogla, Holdegotal, Vusieri,andKanchon. Cluster analysis considering percent reduction of growth parameters categorized the genotypes into four main sub-clusters and importantly, the salt-tolerant landraces were placed in the same cluster cluster-II with salt-tolerant check genotypes. The results of principle compon
