以20份从农家种选育的自交系和6份测验种按不完全双列杂交组配120个杂交组合为试验材料,以玉米自交系总配合力效应为指标,采用类平均法进行聚类分析。结果表明,20份自交系大致可分为5大类:第1类群为铁13;第2类群为牛11、呼兰8趟、五常白头霜、呼兰老来瘪、冬黄、五常黄金塔、早大黄、宾县老来瘪;第3类群为青冈牛尾黄、五常60天还家、珍珠粟、呼兰红稂子、五常大金顶、风白12、龙江黄马牙;第4类群为木兰白头霜、大四、kl3;第5类群为克830。从组配方式看,地方种质资源与供试6大杂优类群均具有较强的杂种优势,说明地方种质资源的遗传基础比较丰富,但Lancaster×地方种质、Ried×地方种质、旅系×地方种质在利用地方种质组配出现强优势组合的概率相对较多。
以20份從農傢種選育的自交繫和6份測驗種按不完全雙列雜交組配120箇雜交組閤為試驗材料,以玉米自交繫總配閤力效應為指標,採用類平均法進行聚類分析。結果錶明,20份自交繫大緻可分為5大類:第1類群為鐵13;第2類群為牛11、呼蘭8趟、五常白頭霜、呼蘭老來癟、鼕黃、五常黃金塔、早大黃、賓縣老來癟;第3類群為青岡牛尾黃、五常60天還傢、珍珠粟、呼蘭紅稂子、五常大金頂、風白12、龍江黃馬牙;第4類群為木蘭白頭霜、大四、kl3;第5類群為剋830。從組配方式看,地方種質資源與供試6大雜優類群均具有較彊的雜種優勢,說明地方種質資源的遺傳基礎比較豐富,但Lancaster×地方種質、Ried×地方種質、旅繫×地方種質在利用地方種質組配齣現彊優勢組閤的概率相對較多。

Twenty maize inbred lines from the landraces of Heilongjiang were used to make 120 testcrosses by NC II with 6 testers. Heterosis groups and heterotic pattern of 20 inbred lines were estimated.The results showed that 20 inbred lines were classified into 5 groups: Group I including Tie13; Group II including Niu11, Hulan8tang, Wuchangbaitou Shuang, HulanLaolaibie, Donghuang, Wuchanghuanjinta, Zaodahuang and Binxianlaolaibie;Group I-II including QinggangniuWeihuang,Wuchang60tianhuanjia, Zhenzhusu, Hulanhonglangzi, Wuchangdajinding, Feng-bai12, Longjianghuangmaya; GroupⅣ including Mulanbaitoushuang, Dasi, kl3; GroupⅤ including Ke830. The combing pattern of the hybrid, these land-races had heterosis with 6 heterotic groups which be used. The result also showed that these landraces had abundant hereditary basis. Lancaster ×landraces, Reid ×landraces and Luda Red Cob×landraces had great probability.
