本地農作物小品種是廣南縣歷史悠久的傳統種植的作物品種，是廣大群眾生活的重要食物來源，產量低、品質高。但由于近年來雜交品種大面積推廣，產量較高，嚴重影響本地農作物小品種種植發展，把當地品種推向滅絕和淘汰的邊緣。為把當地現有的本地農作物小品種保護延續，廣南縣農業和科學技術局　　2014年開始對全縣現有本地農作物小品種保護列為科技三項工作重點來抓，并指定廣南縣種子管理站為具體組織實施單位。通過2014年實施后的篩選，2015年重點將廣南縣種子管理站選育的廣稻二號、廣稻四號；八寶鎮大白谷、糯谷；者兔鄉宜樂大紅谷；董堡鄉小粒黃豆；黑支果鄉小金黃玉米、雞腰豆、雀蛋豆（花生豆(dou)）、小花(hua)豆(dou)；珠琳鎮(zhen)小粒花(hua)生、大白豌豆(dou)；五朱鄉老鼠豆(dou)、虎皮(pi)豆(dou)、大白玉米(mi)；舊莫鄉小粒黃豆(dou)等(deng)16個農作物品種納入保護，各實施保護種植2畝，并選(xuan)育及提純復壯。
