奇台无芒雀麦品种比较试验

1988～1990年在乌鲁木齐市老满城进行了奇台无芒雀麦、昭苏无芒雀麦、八农无芒雀麦、林肯无芒雀麦和老芒麦(CK)的品种比较试验。结果表明奇台无芒雀麦产草量很高,极显著地高于对照老芒麦,与林肯无芒雀麦和八农无芒雀麦均属于丰产型品种,其生长速度和再生速度快,饲草品质好,种子产量表现最高,并且抗病虫害能力较好,是新疆优良的禾本科牧草品种,在生产中可以取代老芒麦。奇台无芒雀麦是地方品种,个体间在许多性状上一致性较差,提高该品种的一致性和生长,再生的整齐度是今后育种的重要目标。

Variety Test of Qitai Smooth Brome Grass

During 1988 and 1990, the variety test of Qitai, Zhaoshu, Banong, Lincoln smooth brome grasses (Bromus inermis Leyss.) and Siberian wildrye grass (Elymus sibiricus L.) (CK) was conducted at Laomanchcng, Urumqi. The results showed that the forage yield of Qitai Smooth Brome Grass (Bromus inermis Leyss. CV.Qitai) was high and considerablly significantly higher than the ek, Siberian wildrye grass. All of Qitai, Lincoln and Banong smooth brome grasses belonged to the productive variety. As it had high rates of growth, regrowth, a good forage quality, the highest seed yield and resistances to leaf disease and insect, Qitai was a fine cultivar in forage grasses in Xinjiang and could replace Siberian wildrye grass in forage production.Due to that Qitai was a land race, the uniform of many varietal characteristics was low. Increasing the varietal uniform in growth and regrowth would be the important breeding goal in the future.
