| Abstract: | A comprehensive appraisal is performed on the newly bred of 28 hybrid middle-season rice combinations,with Yangliangyou 6 as a control,a total of 29 combinations,in terms of high and stable yield,adaptability and disease resistance.Two-line hybrid combinations have a total of 24,accounting for 82.76％ of the exhibition,but there were only 5 three-line hybrid combinations have accounting for 17.24％ of the exhibition.There are 13 high-quality two-line cross combinations,representing 54.17％ of the two-line hybrid combinations.In the 8 hybrid combinations,whose yield per unit area is more than that of the control,7 are two-line hybrid combinations,and the last one is the three-line hybrid combination.There are 15 two-line hybrid combinations with whole growth period 10 d shorter than Yangliangyou 6. |
