M Fengliangyou No.2 (Rice)
The female parent M8064S has a recessive marker of the lethal gene sensitive to bentazon. The whole growth period of the hybrid combination is 141d, the tillering ability is strong, the plant height is 130.2cm, the total grains per panicle is 263.6, the seed setting rate is 76.6%, and the 1000-grain weight is 25.6g. Main advantages: moderate ripening period and safe purity. In the combination of male sterile lines with lethal markers of bentazon sensitive gene, when abnormal self-mixing occurs, rice field herbicides can be applied at the seedling stage of hybrid seeds to selectively kill the self-crossing seedlings of male sterile lines to ensure the hybrid rice field.
