合油77—4是合浦县农科所从合油77中系统选育而成的花生新良种。经几年观察及小区试验,它保持并强化了原品种的丰产性,又改良其荚果大小不均匀,果壳较厚的缺点,出仁率由70％提高到73％,因而深受群众欢迎。为了更充分验证该品种在大面积生产上的表现,加快种子繁殖及探索其高产栽培的配套技术,我们在1985年秋繁准备了 Oil 77-4 is a new breed of peanut that was systematically bred from He You 77 by Hepu County Agricultural Science Institute. After several years of observation and plots experiments, it has maintained and strengthened the high yield of the original varieties, but also improved its pod size is not uniform, the shortcomings of thick shell, kernel rate increased from 70% to 73%, and thus popular . In order to more fully verify the variety performance in large-scale production, speed up seed multiplication and explore its high-yielding cultivation techniques, we prepared in the autumn of 1985
