Detailed Introduction to the Rice Variety Fengliangyou No. 2

The female parent M8064S carries a recessive marker gene for bentazon-sensitive lethality. The hybrid combination has a whole growth period of 141 days, strong tillering ability, a plant height of 130.2 cm, 263.6 total grains per panicle, a seed-setting rate of 76.6%, and a 1000-grain weight of 25.6 g. Main advantages: moderate maturity and purity safety. By using a male sterile line combination with a bentazon-sensitive lethal gene marker, when abnormal self-pollination contamination occurs, paddy field herbicides can be applied at the hybrid seed seedling stage to selectively kill self-pollinated seedlings of the male sterile line, ensuring the field production purity of the hybrid rice. Special cultivation technique: spray the chemical bentazon at the 2-4 leaf stage after sowing to carry out impurity removal and purity preservation technology, which can selectively kill self-pollinated seedlings of the male sterile line and ensure the field purity of the hybrid rice.
