| Xinjiang Yili prefecture of Xinjiang uygur autonomous region Xinyuan county is located in the northwest of our country.It is surrounded.It can form an independent ecological zones,wheat stripe rust is also one of the main diseases for local wheat production.Studies have confirmed that the barberry is one of the aLternate master of wheat stripe rust,and wheat stripe rust in our country new strains pathogenic mutations and play a role in the process of the occurrence of wheat stripe rust.In the Xinjiang,wheat variety and quantity is numerous.It has a wide distribution.For the berberis rust cupula of Xinjiang and wheat stripe rust,there are correlation or not that still lock of relevant research and reporting.For wheat rust incidence and berberis at X inyuan,we investigate and sample here.And conduct correclation studies.Based on wheat rust incidence and B.het eropo da Schneid numerous at Xinyuan county in Xinjiang conducting investigation and samp ling.The 600 of wheat stripe rust and berberis article rust correlation on B.heteropoda Schneid and wheat leaf was studied using SSR molecular markers.At the same time,genetic correlation analysis was carried out on wheat stripe rust in central,north and south China in 2017.It turns out:1.Genetic correlation analysis of the rusts of B.heteropoda Schneid and wheat in Xinyuan county,Xinjiang.Originating in yining,xinjiang region two host of article 18 7 of the rust sample correlation analysis of genetic diversity.Using Poppr software for data analysis.The results show that in the clump of B.heteropoda Schneid at the town of Nalati,The stripe rust fungus of Morocco and the stripe rust fungus of the B.hete ropoda Schneid have the source communication.It is the main host of wheat stripe rust fungus.In combination with the time of onset,it can be speculated that the infection relationship of stripe rust fungus is the mulberry-Morocco-spring wheat in the field.At the same time,the correlation of wheat stripe rust in linzhi?xinjiang and Gansu were analyzed.The results showed that there was a significant difference between Tibet and two other groups.2.The genetic diversity of wheat stripe rust near the Xinjiang was analyzed by SSR molecular markers.Genetic analy?is of wheat stripe rust was carried out using SSR molecular markers.The results showed that the genetic diversity of wheat stripe rust was more abundant in 3 5 4 different cultivar s in the northwest,southwest and central China.There was a difference in the genetic diversity of wheat stripe rust in large area.There is a certain genetic differentiation between groups and group s.Genetic variation mainly exists within the group.Relative northwest,Sichuan,Yunnan,Guizhou and northwest of Hubei,Jangsu,north China bacteria source correlation is higher.The wheat stripe rust is a sex genetic group in Gansu and the surrounding area.Preliminary speculations that the wheat stripe rust fungus in central China is mainly transmitted by the southwest region of China in 2017.3.Genetic diversity of wheat and barley stripe rust was analyzed using SSR molecular markers at Sangdui town,Daocheng county,Sichuan province.Wheat stripe rust fungus,barley stripe rust fungus to change the host in the greenhouse.Then divided into 48 small group s to analysis by S S R.The results showed that there was a certain amount of bacterial interaction between barley and wheat under suitable conditions.The genetic diversity of stripe rust was higher in wheat population. |
