“粤油551”是我组于一九六八年秋植用“粤油22号”为母本与“粤油431”(狮头企×伏花生)杂交选育而成。一九七一年秋植进行产量签定,亩产五百七十六斤半,居首位。一九七二年参加品种比较试验,春、秋两造分别为四百三十五斤六和四百一十三斤一均居首位比标准种粤油22号增产百分之一十六点九和百分之七点七。旱地种植也有明显的增产效果。通过三造产量 “Yueyou 551” was a result of crossbreeding between “Yueyou No. 22” and “Yueyou 431” (Shitouqi × V. peanut) in the autumn of 1968 in our group. Autumn planting in 1981 signed a yield of 576 kilograms per mu, ranking first. In 1972, they took part in the comparative trials of varieties. In spring and autumn, the inventories of the two varieties were respectively 435kg, 6 and 411kg, respectively, representing the first increase over the standard type Yueyou 22 by a total of 16% Nine points and seven point seven percent. Dry land cultivation also has obvious yield increase. Made through three production
