摘  要:
The field demonstration of newly developed super hybrid rice was carried out every year in order to obtain the corresponding field practices for maximum tapping the yielding potential of the new promising combinations on the headquarters farm at the center.Two hybrid rice varieties for the middle season rice in Hunan were grown in 2006.Lianyou 29(8820S/R29)yielded 12 567.6 kg/hm2 estimated via the harvested actual area of 37.001 8 by the output examination group of the institute.In this paper the morphological,physiological and ecological characteristics of the hybrids were mentioned.The matching integrated field managements for the two outstanding hybrid rices were proposed.
