玉米育种的目标性状 我省农业生产水平和社会消费水平较高,在制订玉米育种目标时往往要求新品种有众多的目标性状,如高产,优质(营养品质、加工品质、食味风味),抗多种病害(大斑病、小斑病、青枯病、黑穗病、病毒病)和虫害(玉米螟),耐各种不良环境(耐涝渍、耐干旱、耐开花期高温等),抗倒伏,适应广(能适应徐淮、沿江沿海、两泰高沙土和丘陵地区)。此外,有对株型(适应密植)、粒型和粒色(适应食用、饲用和贸易)、耐荫蔽性(适应麦—绿肥套作、粮棉间作)、较大绿色营养体和绿叶寿命(适应粮食青贮饲料兼用)的要
Target traits of maize breeding In our province, the level of agricultural production and social consumption are relatively high. In the process of formulating the goal of maize breeding, it is often required that the new breed has many target traits, such as high yield, high quality (nutrition quality, processing quality, taste flavor) (Leaf spot, spot blight, bacterial wilt, smut, virus disease) and pest (corn borer), resistance to all kinds of adverse environment (waterlogging, drought resistance, Lodging, wide adaptation (to adapt to Xuhuai, along the coast, two Thai high sand and hilly areas). In addition, the plant type (adapted to close planting), grain and grain (adapted to food, fodder and trade), shading resistance (adapted to wheat - green manures, intercropping), larger green nutrients and green leaf life (To adapt to the use of food silage) to be
