Abstract

The invention discloses molecular markers for the rice cold-tolerant major QTL qCTS12 and an identification method and application of the molecular markers. The molecular markers for the rice cold-tolerant major QTL qCTS12 are M5 and M6, PCR amplification is conducted by using primers corresponding to the molecular markers M5 and M6, and an amplified product is detected. The identification methodof the molecular markers M5 and M6 is used in location of the rice cold-tolerant qCTS12. By using the molecular markers M5 and M6, whether there is the cold-tolerant major site in a rice variety or not can be effectively detected, and the efficiency of selecting a cold-tolerant material in the rice seedling stage is quickly improved. By means of the molecular markers, location of the cold-tolerantqCTS12 can be accelerated, and after the molecular markers are used for helping selective breeding, the breeding progress is accerated.

Description

technical field

[0001] The invention belongs to the field of molecular genetics, and specifically relates to a molecular marker of rice cold-tolerant main effect QTL qCTS12 and its identification method and application thereof, and is suitable for the molecular marker of rice seedling stage cold-tolerant main effect QTL qCTS12 and its selection of cold-tolerant varieties in rice seedling stage. applications in education and genetic resource screening. Background technique

[0002] As one of the most important food crops in the world, rice production is of great strategic significance for solving future global food problems. However, the main rice producing areas in my country often suffer from chilling damage due to low temperature stress during the rice planting period. For example, the Northeast region will encounter chilling damage every 3 to 4 years on average; rotten seedlings of early rice; "cold dew wind" in late rice in the south will cause delayed heading of rice; t...
