摘 要: | 大豆花叶病毒(SMV)种子传染率与品种间的抗性和SMV不同株系呈正相关,而与种子的褐斑粒率和种株的病情指数相关性极不显著。1号株系的种传病苗率高于2号和8号株系。高抗SMV种传的品种,能抗8个株系的传染。可以通过选育和筛选种传病苗率低的品种推广,减少本病的初次侵染来源。

Abstract: | The seed infection rate of SMV positively correlated with the dise- ase resistance between cultivars and the different strains of SMV, but thè correlation did not noticeable between the seed infectionrate and seed-mottling rate or disease index of seed plants. The infected seedling rate of seed-borne SMV strain 1 was higher than strain 2 or 3. The cultivar which highly resist seed infection of SMV would be re- sistant to all 3 srains. Primary infection source may be reduced by breeding and selecting the variety with the lower infected seedling rate of seed-borne SMV. |
