Abstract  

We analyzed the yield, quality and disease resistance traits of fresh maize cultivars from regional testing in Zhejiang Province from 2010 to 2016. The results showed that the yield, quality and disease resistance traits of the 165 fresh maize cultivars were significantly different between cultivars and years. In the yield trait, the variation coefficients of sweet corn varied from 3.7% (growth period) to 17.8% (ear height), whereas the variation coefficients of waxy corn varied from 2.2% (growth period) to 11.5% (1 000-grain mass). In the quality trait, the variation coefficients of sweet corn varied from 2.6% (total score) to 6.4% (flavor), whereas the variation coefficients of waxy corn were from 1.9% (smell) to 8.4% (flavor). All the examined maize cultivars exhibited low resistance to corn borer, and no high resistance cultivars were found. Moreover, their resistance to southern leaf blight was low, but the percentage of cultivars with the southern leaf blight resistance had a tendency of increase. By contrast, the total level of resistance to northern leaf blight was generally good. No cultivars with high resistance to sheath blight were found, but the resistance to sheath blight was improved in recent years. The total level of resistance to stem rot was good, and furthermore the percentage of stem rot resistant cultivars was increased continually. These results suggest that the resistance level to main diseases and insect pests of fresh maize cultivars in Zhejiang Province is relatively low, but has a growing trend; the comprehensive resistance level is also constantly improved. Most of the cultivars possess a high-yield trait (≈1×104 kg/hm2), medium quality (total score of 84-86) and medium resistance level. Combined the analysis of regional test data with the actual production of Zhejiang Province, some specific objectives of fresh maize breeding are put forward in this study.

浙江省鲜食玉米新品种产量、品质和抗性分析及其育种目标选择

以2010—2016年浙江省鲜食玉米区域试验数据为材料,分析参试品种的产量、品质和抗性性状。结果表明,165个鲜食玉米品种的产量、品质和抗性性状在品种间、年份间均有显著差异。在产量性状中,甜玉米的变异系数为3.7%(生育期)~17.8%(穗位高),糯玉米的变异系数为2.2%(生育期)~11.5%(千粒质量);在品质性状中,甜玉米的变异系数为2.6%(总评分)~6.4%(风味),糯玉米的变异系数为1.9%(气味)~8.4%(风味)。参试品种对玉米螟的整体抗性较差,无高抗品种;对小斑病抗性水平较低,但抗性品种比例有上升趋势;对大斑病抗性水平总体较好;无对纹枯病高抗的品种,但对纹枯病抗性水平在提高;对茎腐病抗性水平总体较好,抗性品种比例有上升趋势。浙江省鲜食玉米品种对主要病虫害的抗性水平较低,但有逐步提高的趋势,综合抗性水平也在不断增强。多数品种产量较高(1×104 kg/hm2以上),品质中等(总评分84~86分),处于中抗水平。同时,本研究结合区域试验数据与浙江省的实际生产,提出了鲜食玉米育种的具体目标。
