高产抗病水稻新品种的研究

Study on New Rice Cultivars with Higher Yield and Stronger Resistance

对供试的水稻新品种进行了营养生长期分蘖消长变化和抗纹枯病的研究。通过定点、定时观察和抗性测定结果表明 :维七早 5 80有效分蘖数和抗纹枯病性均呈明显优势 ,具有高产、抗病的特点 ,值得大面积推广。维六早 2和水晶占次之。

The percentage of tillering in vegetative period and resistance to banded sclerotial blight (Rhizoctonia solani)are researched in this paper. Using investigation of location and time test ,and determining resistance, the results indicate: the amounts of effective tillering and resistance of Weiqizao 580 are the most notable superiority, with higher productivity. This caltivar is worth to extending in the larger areas. Caltivars weiliuzao 2 and Shuijingzhan are the next best.
