甜玉米自交系生育进程与双亲播种差期关系研究

Correlation between the Development of Sweet Corn Inbred Lines and the Sowing Interval Days of Parents

通过观察、记载、分析 4个遗传稳定、性状整齐、类型差异较大、耐自交能力较强的甜玉米自交系出叶进程、发育特点 ,把叶差法和时差法进行有机的结合 ,确定部分双列杂交组合双亲的播种差期。为自交系配合力测定。

We will arrange sowing interval of incomplet dialle cross parents by observing, Recording and analysing the leaves age and development of four sweet corn inbred lines.which the heribility is stable, All character is tidy, Type is different, and inbred tolerant is better. Combinating the interval between parents leaf age and anthesis silking also. It is necessary for parents which come into flowering at same time when combining ability and maize hybrid seeds will be tested or producted.
