| Abstract: | The relationship between the earing percentage of main stems and tillers and wheat grain yield was analysed from 1991 to 1997. The emergence and earing percentages of tillers at low nodes of main stems in high yielding population were relatively high. Under the condition of obtaining suitable ear number, raising the earing percentage of main stems and tillers could increase grain number per ear and grain weight resulting in high yield. Cultural techniques could effectively regulate the earing of tillers. |
