In vitro screening for salt tolerance in Rice ( Oryza sativa )
An experiment was conducted to study the performance of rice genotypes for salt tolerance under in vitro condition. Seven genotypes include salt tolerant (Pokkali, CSR 10, TRY 1 and TRY2), moderately tolerant to salt (White Ponni and BPT 5204) and susceptible (IR 29) were used for this study through embryo culture technique. Callus was initiated in MS medium + 2 mgl 2,4D + 0.5 mgl Kin and diffe...
متن کاملMapping QTLs for Physiological Traits Associated with Drought Tolerance in Rice (Oryza Sativa L.)
Drought is the most important limiting factor for crop production and it is becoming an increasingly severe problem in many regions of the world [1]. According to FAO statistics, the percentage of drought affected land areas more than doubled from the 1970s to the early 2000s in the world [2]. Drought is a world-spread problem seriously influencing grain production and quality and with increasi...
متن کاملOsMSR2, a novel rice calmodulin-like gene, confers enhanced salt tolerance in rice (Oryza sativa L.)
OsMSR2 is a novel calmodulin-like gene in rice. Previous study has been demonstrated that OsMSR2 was a cold, drought and heat-inducible gene. However, the role of OsMSR2 in rice stress response is still unclear. To reveal the function of OsMSR2 involved in stress response, the expression pattern and effects of overexpression of OsMSR2 on salt stress were analyzed in rice. Quantitative real-time...
متن کاملMarker Aided Incorporation of Saltol, a Major QTL Associated with Seedling Stage Salt Tolerance, into Oryza sativa ‘Pusa Basmati 1121’
Pusa Basmati 1121 (PB1121), an elite Basmati rice cultivar is vulnerable to salinity at seedling stage. A study was undertaken to 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) marker RM 3412, tightly linked to Saltol was used for for...
متن کاملSimultaneous Improvement and Genetic Dissection of Salt Tolerance of Rice (Oryza sativa L.) by Designed QTL Pyramiding
Breeding of multi-stress tolerant rice varieties with higher grain yields is the best option to enhance the rice productivity of abiotic stresses prone areas. It also poses the greatest challenge to plant breeders to breed rice varieties for such stress prone conditions. Here, we carried out a designed QTL pyramiding experiment to develop high yielding "Green Super Rice" varieties with signific...
