Heterosis Analysis for Physio-Morphological Traits in Relation to Drought Tolerance in Rice (Oryza sativa L.)
Rice (Oryza sativa L.) is the most important food crop of the world; but drought stress is a serious limiting factor to rice production and yield stability in rainfed areas. Breeding for drought tolerance is a challenging task because of the complexicity of the component traits, screening technique, environmental factors and their interaction. The major setback in drought tolerance breeding is ...
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 کاملCorrelation Studies in Rice (Oryza sativa L.)
Seventy genotypes of rice (Oryza sativa L.) were evaluated during Kharif 2012 to study the nature and extent of correlation among yield and yield attributing characters, days to 50 per cent flowering, days to maturity, number of effective tillers per plant, plant height, panicle length, number of grains per panicle, 1000-grain weight, grain yield per plant, kernel length, kernel breadth and L/B...
متن کاملIn 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 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...
