摘要：The seed production of male and female parent of ''Hunzhi 1'' contained bentazon susceptible gene was studied.The result showed that spraying 3.375 L/hm2 48%bentazon aqua could control the self-pollinated fertilization rate below 1.0%and survival plant rate was 0.The spray of bentazon would not influence MC526 pollen vitality.Seed setting rate of female parent was not obvious different from that of control group with spraying bentazon aqua more than 3.375 L/hm2 from the sprouting appearing period to full he...
