Technical method of creating parent of polygene type colony heterosis utilization

Abstract

A technical method of creating a parent of polygene type colony heterosis utilization is a new technology of breeding the parent of the polygene type colony heterosis utilization. The technical method of creating the parent of the polygene type colony heterosis utilization can effectively polymerize merits of resource materials. The technical method of creating the parent of the polygene type colony heterosis utilization includes the following steps of constructing a recombinant inbred line through two subject parents, wherein the two parents hybridization F1 is obvious in superiority and preferably one of the two parents is a local main cultivar, selecting a monophyly from an F5 generation, wherein agriculture characters of the monophyly is basically consistent with that of a female parent, screening a monophyly from an F6 generation through a markers assisted selection technology, wherein genetic background of the monophyly is approximate to a male parent, paring the monophyly screened from the F6 generation and the original female parent, identifying characters including heterosis, resistance, uniformity, quality and the like of an F2 genration, and breeding a new material, wherein the new material and the female parent have complementary advantages, the plant type of the new material is ideal, the resistance of the new material is wide, the quality of the new material is good, characters influencing the colony regularity are all shown consistently, the genetic background difference of the new material is large, and heterosis of the F2 generation is prominent in superiority. The technical method of creating the parent of the polygene type colony heterosis utilization effectively solves the problem that parent selection of the polygene type colony heterosis utilization is difficult and enables teleonomy of the parent breeding to be more explicit and controllability of the parent breeding to be stronger.

AI Technical Summary

Benefits of technology

This patented method helps gather resources from different types at once by combining them together into better ways that make it easier or harder to choose between multiple genes within each type. It also allows us to identify which ones have important traits and potential uses based on their DNA sequence similarity compared against other parents' genomic data. Overall this makes developing new sources faster and stronger than current methods while reducing costs associated therewith

Problems solved by technology

This patented technical solution described by Japanese researchers describes how improving the efficiency at producing mixed types (hybrids) of Chinese paddy rice can help increase its potential use across different geographic areas or regions where there may have issues related to poor yields caused by lack of specific traits like pollen count that could lead to reduced productivity during harvest season due to increased costs associated with hybrid seeds produced through traditional methods such as crossing over between two genetically distinct strains called Xianglongbing mutants.
