Mapping 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 کاملStudies on root traits for drought tolerance in rice (Oryza sativa L.) under controlled (PVC pipes) condition
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. In order to design an efficient breeding program for synthesis of new varieties with virtues of drought tolerance and high yielding ability, it is necessary to identify potential parents that combine well for both yield and...
متن کاملMapping quantitative trait loci (QTL) associated with cooking quality in rice (Oryza sativa L.)
A mapping population consisting of 236 F2:3 families derived from the cross between two rice varieties, Gharib as female parent (with good cooking quality) and Sepidroud as male parent (with poor cooking quality) was used to analyze the quantitative trait loci (QTLs) associated with amylose content (AC), gelatinisation temperature (GT) and gel consistency (GC). A total of 105 single sequence re...
متن کاملMapping of Novel QTL Regulating Grain Shattering Using Doubled Haploid Population in Rice (Oryza sativa L.)
The critical evolutionary step during domestication of major cereals was elimination of seed shattering because the easy-to-shatter trait in wild relatives results in a severe reduction in yield. In this study, we analyzed the QTLs associated with shattering employing a high-density genetic map in doubled haploid (DH) population of rice (Oryza sativa L.). A genetic linkage map was generated wit...
متن کاملQTL mapping of grain length in rice (Oryza sativa L.) using chromosome segment substitution lines.
Chromosome segment substitution (CSS) lines have the potential for use in QTL fine mapping and map-based cloning. The standard t-test used in the idealized case that each CSS line has a single segment from the donor parent is not suitable for non-idealized CSS lines carrying several substituted segments from the donor parent. In this study, we present a likelihood ratio test based on stepwise r...
