Problems solved by technology

Most genes for root traits are associated with genes related to fertilizer and water use, agronomic traits, and yield traits (Bai et al., 2013), but few closely linked markers have been reported

Abstract

The invention discloses an SNP (single nucleotide polymorphism) site relates to characters of a plant root system and application thereof. The SNP site related to the characters of the plant root system is a 55th nucleotide from a tail end 5' in SEQ ID No.4, and the 55th nucleotide is C and / or G; a DNA segment shown in SEQ ID No.4 is at a position 19.3cM on a wheat chromosome 1BS. The invention provides a new root system major gene site QRt.caas-1BS and an auxiliary excellent wheat root system screening SNP site; wheat with excellent root system characters can be screened by utilizing the SNP site, so that the SNP site plays an important role in wheat root system related breeding.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to an SPN site related to plant root traits and its application. Background technique [0002] Breeding high-yield, wide-ranging, and water-fertilizer-efficient new wheat varieties requires not only excellent agronomic traits, but also a stable and well-developed root system and long-lasting root vitality. Due to the complexity of the wheat root growth environment and the limitations of research methods and means, the genetic research on root traits lags behind that of aboveground tissues. Therefore, breeders still lack the knowledge and understanding of the genetic rules of wheat root traits, which limits This hinders the genetic research process of variety roots and restricts the cultivation of new varieties with high yield and wide adaptability. With the deepening of researchers' understanding of the importance of the root system, some methods of root system research have been devel...
