| Abstract: | We inserted a new gene with resistantance to blight disease,Xa22t]in mainy cultivated uariety Diangengyoul by backcross,and got 5 rice individuals,in which diease resistance and agronomic traits all reached requirements through assisted selection of the aim characters and background by molecular marker based on PCR,combining with the identification of inoculation technology in field in BC3F1 group.The disease-resistance of Diangengyou1 was improved,and provided the corresponding information for the next work of disease-resistant molecular breeding. |
