| 摘 要： | BC8241Ht是1973年从前南斯拉夫引进的含欧洲玉米种质资源的杂交种,经过一系列遗传改良后,已衍生出8个成型自交系,并组配出了17个杂交种(组合)。分析发现,以BC8241Ht种质为主线对其实施的一系列改良步骤行之有效,衍生出来的系列自交系在利用上主要有4种模式:①直选系及其与墨改种质改良系×Lan.种质改良系;②直选系及其与墨改种质改良系×西南地方种质改良系;③直选系及其与墨改种质改良系×旅大红骨种质改良系;④BC8241Ht种质与墨改种质改良系×Reid种质改良系。

| Abstract: | BC8241Ht was an European maize germplasm(hybrid) that we introduced from original Yugoslavia in 1973, eight successful lines were derived from BC8241Ht after it was passed a series of inheritance improvement, and we has combined 17 hybrids(crosses) with regarding these lines as hybrid parents. By analyzing and finding out, we regarded BC8241Ht as major germplasm, and it was advisable and effective for a series of heredity improvement procedures to one. There are mainly four cross models when the lines derived from this germplasm were used cross parents in utilization, (1)the inbred lines selected immediately from BC8241Ht or improved lines of the one with CIMMYT ×improved lines stemmed from Lan.; (2)the inbred lines selected immediately from BC8241Ht or improved lines of the one with CIMMYT×improved lines originated southwest local germplasm; (3)the inbred lines selected immediately from BC8241Ht or improved lines of the one with CIMMYT×improved lines from Lvdahonggu germplasm; (4) the improved lines from BC8241Ht with CIMMYT×improved lines stemmed from Reid. |
