Effects Of Glyphosate On Jinda73and RR1Metabolism And New Varieties Glyphosate-resistant Soybean Breedinggroup

In this study, Jinda73and paternal RR1and hybrids34strains as experimental material, the first pro-spraying glyphosate measured chlorophyll, soluble sugar, MDA, relative conductivity and prolyl changes in acid content; then examined the parents and34offspring resistance to glyphosate; Finally, parents and agronomic traits34offspring were analyzed. Use of the Quantity One, Excel, SPSS software, parental genetic characteristics and34progeny yield, quality and resistance were studied for breeding high-yield soybean glyphosate resistant new varieties provides a theoretical and practical basis. Specific conclusions are as follows:1、Determination of chlorophyll, soluble sugar, MDA, relative conductivity changes and proline content in the parent to discuss the impact of parental glyphosate spraying glyphosate on a daily basis by the two parents.2、By conducting field observations and laboratory PCR technology to identify after spraying glyphosate imported cases parents and34hybrids of field resistance and glyphosate-resistant gene, and clarify the lines of glyphosate-resistant case.3、Agronomic traits of parents and their offspring were correlation analysis, principal component analysis and cluster analysis, draw some factors affecting plant yield and agronomic traits screened out some good lines.4、Parents and offspring of protein and fat were measured:By determination of parents and their offspring34strains of protein and fat content, screened out of three protein and fat content than the parent strains.
