对吉林省12个中晚熟主栽耐密玉米杂交种进行综合分析与评价。结果表明,参试品种均达到国家一级玉米容重标准,商品品质优良。淀粉含量农华101最低,为淀粉普通型玉米;京科968最高,为75.41%,达到国家高淀粉玉米一级标准;大民899、迪卡519、禾育203、良玉208和禾育35为二级标准;吉农玉833、吉单50、金园15、禾育47和郑单958为三级标准。除了农华101,其他品种子粒是玉米淀粉加工的优质原料,均可以作为高淀粉玉米品种进行种植推广。产量表现为农华101>吉单50>京科968>良玉208>迪卡519>大民899>吉农玉833>禾育35>禾育203>金园15>郑单958(CK)>禾育47。对品种产量进行方差分析,结果表明,区组间差异不显著,品种间差异显著。
A comprehensive analysis and evaluation of 12 mid-late maturing resistant sweet corn hybrids in Jilin Province was conducted. The results showed that the tested varieties all reached the national standard of bulk density of maize and the quality of the products was good. The lowest starch content of agricultural China 101, starch common type of corn; Beijing Section 968 highest, 75.41%, reaching the national standard of high starch corn; the public 899, Di Card 519, Wo Yu 203, Liang Yu 208 and Heyu 35 As secondary standard; Ji Nongyu 833, Ji Dan 50, Jinyuan 15, Heyu 47 and Zheng Dan 958 for the three standards. In addition to Nong Hua 101, other varieties of grain corn starch processing of high quality raw materials, can be used as high starch corn varieties for planting and promotion. Production performance of Nong Hua 101> Jidan 50> Beijing Branch 968> Liang Yu 208> Dhaka 519> Damin 899> Ji Nongyu 833> Wo Yuk 35> Wo Yuk 203> Golden Garden 15> Zheng Dan 958 (CK) > He Yu 47. Analysis of variance of yield showed that the difference between the two groups was not significant and the difference among varieties was significant.
