12个鲜食糯玉米品种比较试验综合评价

Comprehensive Evaluation of Comparative Experiments on 12 Fresh Waxy Maize Varieties

为了促进广西鲜食糯玉米产业持续稳定发展,筛选适宜鲜食糯玉米新品种。在广西横州市对12个糯玉米品种进行品种比较试验,测定分析糯玉米相关农艺性状,通过灰色关联分析法分析各农艺性状与鲜穗产量的相关性。美玉17号和美玉爽甜糯502鲜穗产量分别为1308.4kg/667m^(2)和1260.3kg/667m^(2),比对照分别增产26.1%和21.5%。农艺性状与鲜穗产量的关联度为:百粒重>穗行数>穗粗>穗长>生育期>株高>出籽率>穗高>行粒数。百粒重、穗行数和穗粗对糯玉米鲜穗产量影响较大。根据农艺性状表现综合判断,美玉17号和美玉爽甜糯502综合表现最好,其次是微甜糯1号和金糯1915,适宜在广西横州地区推广。

This article aims to promote sustained and stable development of Guangxi's fresh waxy maize and screen new varieties suitable for fresh waxy maize.A variety comparison experi‐ment was conducted on 12 waxy maize varieties in Hengzhou,Guangxi to determine and analyze the relevant agronomic traits of waxy maize.And correlation between each agronomic trait and fresh ear yield was analyzed through grey correlation analysis.The fresh ear yields of Meiyu 17 and Meiyu shuangtiannuo 502 were 1308.4 kg/667m^(2) and 1260.3 kg/667m^(2),respectively,which were 26.1%and 21.5%higher than that of CK.The correlation between agronomic traits and fresh ear yield were as follows:100-grain weight>ear row number>ear diameter>ear length>growth period>plant height>kernel rate>ear height>kernel per row.The 100-grain weight,ear row number,and ear diameter sig‐nificantly influence fresh ear yield.Given comprehensive evaluation results of agronomic traits,Meiyu 17 and Meiyushuangtiannuo 502 have the best performance,followed by Weitiannuo 1 and Jinnuo1915,indicating that they are suitable for plant in Hengzhou.
