摘要
矮仔占是广西容县的农家水稻品种.五十年代推广至长江流域12个省区,种植面积1100万亩,是我国第一个亩产超500公斤的籼稻品种.它具有矮秆、耐肥、抗倒等许多优良丰产性状.大多主要的优良性状都表现出较高的传达力.以矮仔占或具有矮仔占血缘为亲本的杂交衍生品种据不完全统计达112个,居我国三大水稻杂交亲本之首,成为我国南方稻区推广品种最广泛的血缘.以矮秆为基础,导入多抗的外源基因,育成更为高产优质抗病的品种有广泛的前景.
The rice variety, Ai-Zi-Zhan, is a local one of Rong-xian, Guangxi. In the fifties, this variety was popularized to the Yangtze River Valley with a cropping area of 733 Kha, being the first one of hsien rice yielding over 7500kg per ha. It has short stem, resistante to lodging, yielding more in response to increased nitrogen applications, and a lot of high-yielding characters. Most of the high-yielding characters presented a relative high transmissional capacity. Based on an incomplete statistical figures, there were up to 112 crossing derivative varieties from Ai-zi-zhan or from the parental varieties with the descent of Ai-zi-zhan. It, therefore, occupied the first place of the three main crossing Parents of rice in China, became a most wide descent of the Popularized varieties in southern China. There is a vast vistas to breed more high-yielding and diseaseresiting varieties with high quality by introducing multiresistant exoPlasm on the base of short stemmed varieties like Ai-Zi-Zhah.
