Abstract
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 heading stage.This demonstrated that bentazon aqua had no influence on seed setting rate during florescence of female parent.The weight ratio between male parent seeds and female parent seeds was 1 to 5,then seeds from parents with that weight ratio would be mixedly planted for seed production.With this weight ratio,relative proper structure of panicle and grain would be obtained,panicle ratio was 1 to 4.3,glumous flowers ratio was 1 to 3.5.Cross seed-setting rate of female parent was 72.6% and seed production per hm2 was 66 000 kg.
