| Abstract: | Pre-harvest sprouting is due to both heredity and environment.Therefore,genetic selectionof the moisture-resistant strain is important for preventing pre-harvest sprouting.Most germinated grainsappear in the middle or upper branch of spike.In the same branch germinated grains emerge in the mediumor upper section.The occurrence of germinated grains is related to the extent to which the branch of spikelethangs down.In strain selection it is desirable to choose the one which is strong enough to erect,so as to re-duce germinated grains.Setting percentage and output of hybird seed production is much lower than those ofmaintainer liner or restores liner.Given sufficient pollen and frequent pollination,perhaps setting percen-tage may be increased. |
