Mapping QTLs for Physiological Traits Associated with Drought Tolerance in Rice (Oryza Sativa L.)
ثبت نشده
چکیده
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 increasing population and global climate change the situation is becoming more serious [3]. Rice (Oryza sativa L.) is particularly susceptible to water stress [4,5]. It is estimated that 50% of the world rice production is affected more or less by drought [6].

Identification and Mapping of Quantitative Trait Loci Associated with Salinity Tolerance in Rice (Oryza Sativa) Using SSR Markers
Salinity stress is one of the most widespread soil problems next to drought, in rice growing areas. ReducingSodium (Na+), while maintaining Potassium (K+) uptake in rice are traits that would aid in salinity tolerance.Therefore, the identification of quantitative trait loci (QTLs) associated with those for Na+ and K+uptake, will enable breeders to use marker-assisted selection...
متن کاملIdentification of main and epistatic QTLs for grain yield related traits in a recombinant inbred lines population of rice (Oryza sativa L.)
Rice yield as a complex trait is the main target in most rice breeding programs. To map the main and epistatic QTLs controlling grain yield and yield components, an experiment was carried out using a 129 F6 recombinant inbred lines population (IRA population) originated from a cross between Alikazemi / IR67017-180-2-1-2, in 2015 growing season in two locations, Rasht and Tonekabon, Iran. The e...

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 کاملIdentification 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 ...
