Abstract: To screen the bud stage good cold tolerance, maturity lodging live adaptation of early indica rice germplasm. Studied on 237 different genetic background of early indica rice stable strains of cold resistance during the germination period, identified the growth period, yield and culm traits with lodging properties in the case of direct seeding. The results showed that, 11 new germplasms screened growth period no later than 102 days, leaf blast resistance, cold resistance, live production, and lodging index than the control ‘Jiayu 293’. So screening germplasm sowing varieties adaptability and interoperability will be significantly better than transplanted rice varieties effectively reduce the basic seedling inadequate and late lodging caused damage yield and quality.
