| 摘 要： | 高羊茅（Fectuca arundinacea)在上海等温暖湿润,四季分明的气候过渡区绿色期相对较长,但不能顺利越夏,为了提高其越夏能力,采用选择优良单株自交,或选用优良无性系使之在隔离条件下自由授粉的植物改良方法,培育出草坪型高羊茅新品系“98-8”和“上农矮生高羊茅”。品种（系）比较试验和推广结果表明：新品系在上海地区夏季表现优于对照（美国品种Montauk）,尤以“上农矮生高羊茅”在10个参试材料中抵抗夏季逆境胁迫和胁迫解除后的再生能力为最强,且株型矮化,色泽深绿,深受用户的欢迎。

| Abstract: | Tall fescue ( Fectuca arundinacea Schreb.) has long green period in Shanghai, but it can not survive well after over summering. To increase the tolerance to summer stress, 2 new lines temporarily named "98-8" and "Shangnong Dwarf Tall Fescue" were bred by means of self pollinated or open pollinated. The results showed that these 2 lines performed the better tolerance to summer stress than the control variety Montauk introduced from America. Among 10 varieties or lines tested, "Shangnong Dwarf Tall Fescue" had the strongest tolerance to summer stress and recuperative capacity. Its obvious dwarf and dark green color were quite welcomed by clients. |
