广东省地处南海之滨,阳光充足,雨量充沛,是我国水稻主要产区之一。然而,正是这种特殊的地理环境,给我省带来特殊的灾害性气候,涝害是其中之一,对水稻大面积平衡增产影响很大。关于水稻耐涝性鉴定,国内报道不多。我省野生稻资源丰富。1982—1985年,我们进行了普通野生稻耐涝性鉴定,主要目的是筛选出耐涝新种质,以供育种利用。材料与方法参试材料:普通野生稻(O.sativa L.f.spontanea)1315份,另以栽培品种“珍珠矮11
Guangdong Province is located in the South China Sea, sunny, abundant rainfall, is one of China’s major rice producing areas. However, it is this special geographical environment that brings a special disastrous climate to our province. Waterlogging is one of them, which has a great impact on the large-area balanced increase of paddy yield. About rice waterlogging identification, few domestic reports. Wild rice in our province is rich in resources. From 1982 to 1985, we carried out the identification of the waterlogging tolerance of O. japonica, the main purpose of which was to screen out new waterlogging resistant germplasm for breeding use. MATERIALS AND METHODS Materials for testing: 1315 parts of common wild rice (O. sativa L.f.spontanea)
