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 salttolerant genotypes at the seedling stage using hydroponic system. Different morphophysiological 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 control and EC 7 dSm 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 salttolerant genotypes namely Ghunsi, Nonabokra, Hogla, Holdegotal, Vusieri, and Kanchon. Cluster analysis considering percent reduction of growth parameters categorized the genotypes into four main subclusters and importantly, the salttolerant landraces were placed in the same cluster 2 with salttolerant check genotypes.
