摘要
为助力四川巴中市粮经作物种植结构调整,引进了9个大麦品种,于2021—2022年在巴中市进行品种比较试验,结果显示:各大麦品种农艺性状具有遗传差异,产量变幅为4 738.5~6 030.8 kg/hm^(2),以扬农啤7号和苏啤12号产量最高,川农啤麦1号最低;小穗不孕率变幅为5.5%~12.2%,以川农啤麦1号小穗不孕率最高,浙大9号最低;成穗率变幅为42.0%~58.2%,以川农啤麦1号成穗率最高,驻大麦5号最低;主茎株高变幅为72.9~98.4 cm,以川农啤麦1号株高最高,苏啤12号最矮。
In order to help Bazhong adjust the planting structure of grain and economic crops,9 barley varieties were introduced,and variety comparison tests were conducted in Bazhong from 2021 to 2022.The results showed that there are genetic differences in various agronomic traits,with a yield variation of 4738.5~6030.8 kg/hm^(2),Yangnongpi No.7 and Supi No.12 had the highest yield,and Chuannongpimai No.1 had the lowest yield.The infertility rate of spikelets ranged from 5.5%to 12.2%,with the highest infertility rate of Chuannongpimai No.1 and the lowest of Zheda No.9.The spike growth rate ranged from 42.0%to 58.2%,with the highest spike growth rate of Chuannongpimai No.1 and the lowest of Zhudamai No.5.The main stem plant height was 72.9~98.4 cm,with the highest height of Chuannongpimai No.1 and the lowest of Supi No.12.
