Yields and Quality of Main Fresh Maize Cultivars in Zunyi,China
To screen out the fresh maize cultivars suitable for promotion in Zunyi,China,this study compared the yields and quality of 21 cultivars introduced from other regions and the native cultivar'Wannuo 2000'.The results showed that 11 fresh maize cultivars had the yields exceeding that of'Wannuo 2000'(CK),of which 2 cultivars'Zunhuatiannuo'and'Jingcaibahua'had the yield increases exceeding 20%.'Zhenzhennuo 100'and'Zhenheitiannuo'had lowest yields.Among the 22 cultivars,14 cultivars were rated grade 1(total quality score≥90).'Zunnuo 2130'had the highest score,while'Meitiannuo 1'and'Zhenzhennuo 100'had the lowest score.The correlation analysis showed that the maize yield was positively correlated with the number of rows per ear and kernels per row(P＜0.01,r＞0).The sensory quality was positively correlated with color and flavor,and waxiness/sweetness was positively correlated with odor and flavor(P＜0.01,r＞0)but negatively correlated with skin thickness(P＜0.05,r＜0).The cluster analysis classified 22 cultivars into groups A and B.Group A outperformed group B in terms of yield,yield-related traits,and quality score.Therefore,the cultivars from group A can be selected for promotion in Zunyi.
