Introducing and screening of new high-quality and high-yield fresh maize varieties
There are numerous fresh maize varieties in China.In order to select suitable fresh maize varieties for cultivation in Shuangxi and also align with market demands,this study used seven sweet maize varieties and eight waxy maize varieties as experimental materials.Plant and ear morphology,yield and yield components were further analyzed to explore the key plant and ear morphology factors that affect the fresh maize yield.This study showed that fresh grain yield contributes more to the yield of sweet maize,compared with kernel number and fresh 1000-kernel weight;while the yield of waxy maize is more closely related to fresh 1000-kernel weight.Further more,the correlation between plant and ear agronomic traits including plant height,ear height,ear length,ear diameter,yield and yield components revealed that yield was significantly positively correlated with ear-plant height ratio and ear diameter.In this study,the sweet maize Cuibaitian 926 and Zhetian 922,and the waxy maize Heitiannuo 168 and Zhenuoyu 21 exhibited outstanding comprehensive traits,including high yield and quality,resistance to lodging and strong adaptability.These varieties possessed high popularization value and can be cultivated on a larger area in Pan'an.
