Multivariate Physiological Indices for Salt Tolerance Classification in Indica Rice (oryza Sativa L. Spp. Indica) Suriyan Cha-um
summary. The aim of this investigation was to identity effective criteria for classification of salt tolerance and salt sensitivity in rice cultivars by using multivariate characters. Osmolarity in salt-stressed leaves decreased, and was positively related to low water potential (Ψ w) (r 2 =0.99 and r 2 =1), leading to chlorophyll a degradation (r 2 =0.65 and r 2 =0.77) in both salt-tolerant (H...
متن کاملMolecular and physiological responses to abscisic acid and salts in roots of salt-sensitive and salt-tolerant Indica rice varieties.
The Indica rice (Oryza sativa L.) varieties Pokkali and Nona Bokra are well-known salt tolerance donors in classical breeding. In an attempt to understand the molecular basis of their tolerance, physiological and gene expression studies were initiated. The effect of abscisic acid (ABA) on total proteins in roots from 12-d-old seedlings of Pokkali, Nona Bokra, and the salt-sensitive cultivar Tai...
متن کاملResponse of Two Indica Rice Varieties to Salt Stress
Salinity is one of the most challenging problems that adversely affects growth and development of plants. Therefore, understanding of the mechanisms that enable plants to adapt to salinity stress will ultimately help in the selection of stress tolerant cultivars for exploiting saline soils. The main objective of this study was to examine the effects of NaCl on some physiological and biochemic...
متن کاملPopulation structure analysis and association mapping of blast resistance in indica rice (Oryza sativa L.) landraces.
Rice blast caused by Magnaporthe oryzae is one of the most devastating rice diseases worldwide. To understand the genetic diversity of indica landrace accessions and identify simple sequence repeat (SSR) markers that are associated with blast resistance, a population of 276 indica landraces from across the world was constructed. This population was then used to evaluate the blast-resistance phe...
متن کاملConstruction of Microsatellite Linkage Map and Detection of Segregation Distortion in Indica Rice (oryza Sativa L.)
High density molecular linkage map is a prerequisite to identify the quantitative traits loci. Construction of linkage maps, using mapping populations derived from two major subspecies: indica and japonica in rice, have been reported. However, limited work was conducted in indica subspecies. Present studies focused to construct a molecular map based on indica × indica (Shaheen Basmati × Pokkali...
