K优818是江苏里下河地区农科所最新选育成功的高产优质抗病杂交水稻新品种。2001年通过江苏省审定,2001～2002年在全国区试中表现突出,2003年通过国审。是目前国内杂交籼稻中高产与优质相结合较好的新组合。为了探索K优818的适应性及高产潜力,在江苏里下河地区农科所的大力支持下,我们连续两年在全国各水稻主产区进行K优818试验示范。现将2003年各地试种情况总结如下:
K You 818 is a new breed of high-yielding, high-quality and disease-resistant hybrid rice with the latest selection and breeding in Lixiahe area of Jiangsu Province. In 2001 through the examination of Jiangsu Province, from 2001 to 2002 in the national district test outstanding performance, passed the national trial in 2003. It is a new combination of high yield and high quality of indica hybrid rice in China at present. In order to explore the adaptability and high yield potential of K-818, under the strong support of Jiangsu Lixiahe Agricultural Science Institute, we conducted K-818 experimental demonstration in the main rice-producing areas across the country for two consecutive years. At the moment, the situation of trial cultivation in 2003 is summarized as follows:
