滨海盐碱地特用玉米品种产量和品质综合评价
Comprehensive Evaluation of Yield and Quality of Specialty Maize Varieties in Coastal Saline and Alkaline Areas
摘要
Abstract
In order to screen high-yield and high-quality specialty maize varieties suitable for planting in coastal saline and alkaline land in Shandong province and provide scientific basis for promoting the planting of high-yield and high-quality specialty maize in coastal saline alkali land,in this study,the ear traits,yield,and quality indexes of 10 specialty maize varieties in the Experimental Demonstration Base of Agricultural Saline and Alkaline Land in Dongying city,Shandong province were comprehensively evaluated.The results showed that Zhenghuangnuo 2 and Luheitiannuo 201 had the highest yields of 10 011.51 kg/ha and 8 763.09 kg/ha,respectively,and Zhenghuangnuo 2 had the best performance in terms of 1000-grain weight(313.90 g)and ear number(66 000 ears/ha).In terms of quality,SN7N05 and Luheitiannuo 201 had the highest crude protein content(13.10%and 12.86%),Shannong 201 had the highest crude starch content(72.63%),and Lutiannuo 191 had the highest crude fat content(6.78%),soluble sugar content of the varieties ranged from 1.092%to 3.426%,and straight-chain starch ranged from 0.861%to 1.913%.Lysine content was not significantly different(0.24%-0.26%).Correlation analysis showed that crude protein was extremely significantly negatively correlated with crude starch and extremely significantly positively correlated with lysine.The varieties were classified into three categories by cluster analysis and comprehensive evaluation,Zhenghuangnuo 2 and Shannong 201 had the highest comprehensive scores(88 and 86),with balanced yields and quality,followed by Luheitiannuo 201 and Lutiannuo 191(85).In conclusion,Zhenghuangnuo 2,Shannong 201,Lutiannuo 191 and Luheitiannuo 201 had excellent overall traits and were adapted to saline and alkaline environments,and were recommended to be the preferred varieties for popularization of planting in saline and alkaline land in coastal Shandong province.关键词
