一九七三年夏,东山县良种场以水稻为母本,与观音竹的花粉,进行有性杂交,共授粉六个品种十二穗,最后只有691为母本的组合结了三粒种子。一九七三年秋,将三粒种子播下,只出一苗。F_1谷壳出现粉红色(母本白色),谷粒比母本更元,结实正常,其它性状和熟期同母本差不多。一九七四年春,将杂种一代种子全部播下,杂种二代出现很大分离,谷先有白、赤、红、黑等类型,值株高矮差别很大(高的未抽穗达一百厘米,矮的只七十厘米),生育期差
In the summer of 1973, Dongshan County thoroughbred field took rice as the female parent and had sex hybridization with the pollen of Guanyin bamboo, and pollinated 12 varieties of six varieties in total.
