摘要
以2000~2006年广东省甜玉米区域试验资料为依据,分析了7年152个(次)参试品种的生育期、株高、抗病性、单穗重、产量及综合品质等主要性状表现。结果表明:参试品种的熟期以中熟为主,早熟和晚熟品种所占的比例较小,优质早熟品种的数量有所增加。中秆品种占84.9%,处于绝对优势,矮秆和高秆品种所占的比例较小,分别仅占7.2%和7.9%。育成品种对小斑病、茎腐病和纹枯病3种广东甜玉米主要病害总体抗病性好,但抗性级别在逐渐降低。区试品种鲜苞产量大幅度提高,以优质、优质和高产并重的品种数量和比例稳步增加,育种水平得到很大提高,品种选育正在向优质、高产、多抗相结合的复合性目标转变。
According to the data of Guangdong sweet corn hybrids regional test during 2000~2006,the performance of the main characters,such as maturity period,plant height,disease resistance,single ear weight,yield and comprehensive quality of 152 hybrids were analyzed.The results showed that the medium maturity hybrids made up a larger percent while the early maturity hybrids with high quality,a smaller one.The ratio of medium stalk hybrids is 84.9% while dwarf stalk and high stalk hybrids were 7.2% and 7.9% respectively.The disease-resistance to leaf blight,stem rot blight and banded sacerdotal was quite good in spite of their individual difference in the resistance.The spike yield,the number and ratio of hybrids with good-quality,high-yield shared a great increase.The breeding enjoyed a great improvement.It is concluded that the breeding of sweet corn in Guangdong is good-quality,high-yield and multi-resistance oriented.
