Basmati rice grown in the Indian subcontinent is highly valued for its unique culinary qualities. Production is, however, often constrained by diseases such as bacterial blight (BB), blast and sheath (ShB). The present study developed with inbuilt resistance to BB, ShB using molecular marker-assisted selection. cultivar ‘Improved Pusa 1’ (carrying BB genes xa13 Xa21) was used recurrent parent ‘Tetep’ gene Pi54 quantitative trait loci (QTL), qSBR11-1) donor. Marker-assisted foreground...
Abstract Marker‐assisted simultaneous but stepwise backcross breeding ( MASS ‐ BB ) was utilized in the present study for pyramiding blast resistance genes, Piz5 and Pi54 , from non‐Basmati donors, C101A51 Tetep, respectively, into PRR 78, an elite Basmati restorer line of rice hybrid, Pusa RH 10. foreground selection coupled with stringent phenotypic background analysis carried out hastening recovery recurrent parent phenome RPP genome RPG two separate series to produce BC 2 F 1 plants...
Pusa Basmati 1121 (PB1121), an elite rice cultivar is vulnerable to salinity at seedling stage. A study was undertaken impart seedling-stage salt tolerance into PB1121 by transferring a quantitative trait locus (QTL), Saltol, using FL478 as donor, through marker assisted backcrossing. Sequence Tagged Microsatellite Site (STMS) RM 3412, tightly linked Saltol used for foreground selection. Background recovery estimated 90 genome-wide STMS markers. Systematic phenotypic selection helped in...
Bakanae or foot rot disease caused by Fusarium fujikuroi [teleomorph: Gibberella (Sawada) Ito] is emerging as a serious in rice. The causes both quantitative and qualitative losses to the grains under field conditions. Breeding for resistance promising strategy manage this disease. In study, we used population of 168 F14 recombinant inbred lines (RILs) derived from two indica rice parents Pusa 1342, highly resistant variety Basmati 1121, susceptible map trait loci (QTLs) governing against...
Micronutrient malnutrition particularly of Fe and Zn affects around 3 billion people globally is especially severe in developing countries. More than 90% the Asian population dependent on rice based diet, which low these micronutrients resulting hidden hunger. In present study, evaluation a set 192 Indian germplasm accessions grown at two locations for brown (BR) milled (MR) revealed significant variation micronutrients. The grain concentration was range 6.2 - 23.1 ppm BR 0.8 12.3 MR while...
Abstract Basmati rice is preferred internationally because of its appealing taste, mouth feel and aroma. Pusa 1121 (PB1121) a widely grown variety known for excellent grain cooking quality in the international domestic market. It contributes approximately USD 3 billion to India’s forex earning annually by being most traded variety. However, PB1121 highly susceptible bacterial blight (BB) disease. A novel BB resistance gene Xa38 was incorporated from donor parent PR114- using modified...
Marker-assisted selection is an unequivocal translational research tool for crop improvement in the genomics era. Pusa Basmati 1 (PB1) elite Indian rice cultivar sensitive to salinity. Here, we report enhanced seedling stage salt tolerance improved PB1 genotypes developed through marker-assisted transfer of a major QTL, Saltol . A highly tolerant line, FL478, was used as donor. Parental polymorphism survey using 456 microsatellite (SSR)/QTL-linked markers revealed 14.3% between and FL478....
Abstract Marker assisted backcross breeding was used to transfer Saltol , a major QTL for seedling stage salinity tolerance from the donor FL478 Pusa Basmati 1509 (PB 1509), high yielding and early maturing rice variety. Foreground selection carried out using three markers namely, AP3206f, RM3412b RM10793, linked . In addition, 105 genome-wide SSR polymorphic between PB were in background selection. Among BC 3 F 4 near isogenic lines (NILs) developed, recurrent parent genome recovery ranged...
Bacterial blight and blast are the major diseases causing production losses to an extent of 31.52% 67.79%, respectively. Use chemical pesticides leads increased cost cultivation, degradation environment human health while affecting international trade. The study aimed at developing bacterial resistant Basmati rice varieties assess their impact in farmers' field. A marker assisted selection from intercross backcross derived lines was implemented incorporate resistance genes xa13 Xa21; along...
Aromatic rice of Manipur popularly known as Chakhao is a speciality glutinous rice, for which protection under geographical indication in India has been granted recently. The agronomic and nutraceutical variability the germplasm yet to be genetically characterized. To address this gap, characterization ninety-three landraces agro-morphological traits, grain pigmentation, antioxidant properties, molecular genetic variation was carried out unravel their population structure. Two major groups...
Introduction Toxicity due to excess soil iron (Fe) is a significant concern for rice cultivation in lowland areas with acidic soils. Toxic levels of Fe adversely affect plant growth by disrupting the absorption essential macronutrients, and causing cellular damage. To understand responses Fe, particularly on seedling root system, this study evaluated genotypes under varying levels. Methods Sixteen diverse were hydroponically screened induced levels, ranging from normal excess. Morphological...
Bakanae or foot rot disease caused by Fusarium fujikuroi (teleomorph: Gibberella fujikuroi, Sawada, Wollenweber) is emerging as a serious of rice. A simple, reliable and high-throughput method for screening the would enable rapid germplasm aimed at identifying resistance sources, mapping QTLs/genes developing resistant rice cultivars. In present study, highthroughput, bioassay to screen bakanae was developed compared with conventional technique. This technique involves soaking seeds in...
Drought stress at the reproductive stage in rice is one of most important cause for yield reduction, affecting both productivity and quality. All Basmati varieties, including popular cultivar “Pusa 1 (PB1)” highly sensitive to drought (RSDS). We report first time, improvement a RSDS tolerance, with introgression major quantitative trait locus (QTL), “qDTY1.1” into PB1. The QTL was sourced from an aus variety, Nagina 22 (N22). A microsatellite (simple sequence repeat (SSR)) marker “RM 431”...
Rice germplasm is a rich resource for discovering genes associated with salt tolerance. In the current study, set of 96 accessions were evaluated seedling stage salinity tolerance and its component traits. Significant phenotypic variation was observed among genotypes all measured traits eleven high level at identified.
