Radiosensitivity Study for Identifying the Lethal Dose in MR219 (Oryza sativa L. spp. Indica cv. MR219)
نویسندگان
چکیده مقاله:
The purpose of the research was determine the effects of gamma ray on seed germination, seedling height and root length of Rice (Oryza sativa L. spp. Indica cv. MR219) to identify the Lethal Dosage of the radiation. Paddy seeds of MR219 were exposed to different doses of gamma radiations viz 50,100,150,200,250,300,350,400,450,500,600,700,800,900 and 1000 Gy using 60Co as the radiation source. The effect of radiation was determined by measuring the Seed germination, seedling height, root length and emergence under the conditions of the M1 generation. The research results showed that the differences among radiation treatments significantly affect (p

متن کاملImproving Lowland Rice (O. sativa L. cv. MR219) Plant Growth Variables, Nutrients Uptake, and Nutrients Recovery Using Crude Humic Substances
High cation exchange capacity and organic matter content of crude humic substances from compost could be exploited to reduce ammonia loss from urea and to as well improve rice growth and soil chemical properties for efficient nutrients utilization in lowland rice cultivation. Close-dynamic air flow system was used to determine the effects of crude humic substances on ammonia volatilization. A p...
متن کاملMultivariate 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 Characterization and Comparative Sequence Analysis of Defense-Related Gene, Oryza rufipogon Receptor-Like Protein Kinase 1
Many of the plant leucine rich repeat receptor-like kinases (LRR-RLKs) have been found to regulate signaling during plant defense processes. In this study, we selected and sequenced an LRR-RLK gene, designated as Oryza rufipogon receptor-like protein kinase 1 (OrufRPK1), located within yield QTL yld1.1 from the wild rice Oryza rufipogon (accession IRGC105491). A 2055 bp coding region and two ex...
متن کاملFine mapping of a grain weight quantitative trait locus, qGW6, using near isogenic lines derived from Oryza rufipogon IRGC105491 and Oryza sativa cultivar MR219.
Grain weight is a major component of rice grain yield and is controlled by quantitative trait loci. Previously, a rice grain weight quantitative trait locus (qGW6) was detected near marker RM587 on chromosome 6 in a backcross population (BC2F2) derived from a cross between Oryza rufipogon IRGC105491 and O. sativa cv. MR219. Using a BC2F5 population, qGW6 was validated and mapped to a region of ...

Two new red pericarp transgressive variants (advanced breeding lines from BC2F7 generation) with high yield, derived from a cross between the wild relative, O. rufipogon Griff. and O. sativa subsp. indica cv. MR219, were analysed to determine their proximate composition, total antioxidant activity, phenolic acid composition and tocochromanol content in comparison with two commonly consumed rice...
