Identification of major and minor genes associated with heading date in an indica × indica cross of rice (Oryza Sativa L.)
In this study, quantitative trait loci (QTLs) controlling rice heading date were detected in a F2:3 population derived from a cross between an indica rice variety, Tarom Mahalli, with early heading date, and an indica variety, Khazar, with late heading date. SSR linkage map was constructed using 74 polymorphic markers and 192 F2 individuals and covered a total of 1231.50 cM of rice genome. QTL ...
متن کاملSSR mapping of brown planthopper resistance gene Bph9 in Kaharamana, an Indica rice (Oryza sativa L.).
The brown planthopper (BPH) is one of the most serious insects pests of rice, and the host resistance has been recognized as one of the most economic and effective measures for BPH management. In this study, we conducted a molecular-based genetic analysis of Bph9 in Kaharamana, a Sri Lanka rice variety resistant to BPH insects of East and Southeast Asia. An F2 segregating population composed of...
متن کاملDiversity analysis of indica rice accessions (Oryza sativa L.) using morphological and SSR markers
Morphological and molecular characterization of twenty six landraces rice and four high yielding rice accessions were studied to observe genetic diversity assessment and identification of superior genotypes for crop improvement program. Fourteen morphological and twenty seven DNA based molecular markers, simple sequence repeat (SSR), were used extensively to carry out this study. A wide range o...
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 کاملAgrobacterium-mediated transformation of White Ponni, a non-basmati variety of indica rice (Oryza sativa L.)
We report successful Agrobacterium-mediated transformation of a popular rice variety White Ponni, a non-basmati indica rice (Oryza sativa L.). Scutellumderived calluses of White Ponni were transformed with Agrobacterium strain LBA4404 (pSB1) harbouring the binary vector pMKU-RF2 with rice chi11 gene. Five independent transgenic White Ponni plants were ge nerated from hygromycin-resistant callus...
