Abstract
The invention discloses a kit and multiple PCR detecting method for synchronously detecting the wide compatibility gene S5 and the erect paniclegene DEP1 of paddy rice and belongs to the technical field of agricultural biology. The kit and multiple PCR detecting method has the advantages that the functional markers of the wide compatibility gene S5 and the erect panicle gene DEP1 are designed according to the difference between the wide compatibility gene S5 and non-wide-compatibility genes and the difference between the erect panicle gene DEP1 and non-erect-panicle genes, a PCR reaction system and procedure are optimized to build the multiple PCR method capable of synchronously detecting the wide compatibility gene S5 and the erect panicle gene DEP1, the two target genes can be detected by one PCR reaction, the multiple PCR method is simple, efficient, sensitive and economical as compared with a single PCR method, and the multiple PCR method is suitable for screening, authenticating and molecular pyramiding breeding of wide compatibility and erect panicle seed resources and significant to the increasing of pyramiding breeding molecule selection efficiency and cost lowering.
Description
technical field [0001] The invention relates to a kit for synchronous detection of rice wide affinity gene S5 and erect panicle gene DEP1, and also relates to a multiplex PCR method for synchronous detection of rice wide affinity gene S5 and erect panicle gene DEP1, belonging to the field of agricultural biotechnology. Background technique [0002] Rice is one of the important food crops in my country, and rice production accounts for about 40% of food crops. Increasing rice production is of great significance to ensuring national food security. The increase of rice yield in China mainly has two periods: the first period is the 1950s, when dwarf breeding emerged, and the second period is the widespread promotion of hybrid rice since the 1970s. Chen Wenfu, a rice expert, believes that ultra-high-yield breeding combining the use of heterosis and ideal plant type will surely be a breakthrough point for increasing rice yield in the future. [0003] There are indica subspecies ...
