高产抗病虫早籼品种金早6号的选育

Breeding and Selection of Early Indica Rice with High Yielding, Disease and Insect Resistance——Jinzao 6

以改良早籼品种南京１１的抗病性为主要育种目标，以ＩＲ５８为供体亲本，南京１１为受体亲本进行杂交和１次回交（ＩＲ５８／南京１１２），逐代严格鉴定和选择，育成兼具双亲优良特性的高产，早熟，抗稻瘟病、白叶枯病、褐飞虱、病毒病的新品种金早６号。

The experiment was conducted to improve the disease and pest resistance of Chinese early rice cultivar Nanjing 11.A new variety named Jinzao 6 had been developed by backcross breeding by using IR58 as donor parent and Nanjing 11 as recurrent parent for one cycle (IR58/Nanjing 11 2),then made continuous identification and selection for several generations.Jinzao 6 performed high yielding,early mature,resistant to blast,bacterial blight,rice virus and brown planthopper.
