摘要:
为证实潜育期长、病情发展缓慢、最终病情轻的数量抗性的利用价值, 在接种SMV -Sa 株系条件下, 比较了同一遗传背景、不同发病时期、不同病情下大豆品种主要农艺性状的变异。研究表明早期感染SMV 对大豆产量、褐斑率等的影响显著大于花期感染;病情指数与大豆产量、单株荚数、单株粒数等存在显著负相关, 病情指数越高, 对产量等危害越大;通过比较SMV 对质量抗性、数量抗性和感病3 类大豆品种的影响, 证实数量抗性品种在株高、单株粒数以及大豆产量等方面受SMV 影响显著小于感病品种, 与质量抗性品种接近。说明选育数量抗性品种对控制SMV 危害有实质性意义。
Abstract:
Effect s of soybean mosaic virus on seed trait s of soybean cultivars inoculated wi th strain Sa at dif ferentg row th stages (V1 and R1)were studied .The result s showed that early infection caused g reater reduction ofy ield and higher percentages of seeds mo ttling than late infect ion did .There showed significant negative co rrelationsbetween disease index and ag ronomic characters such as yield per plant , seed number per plant , plantheight and so on .The ef fects of SMV on most of the ag ronomic characters were g reater in susceptible than in resistantcultivars and the similar were found between qualitative resistant cultivars and quant itative resistance cultivars.Therefore , the quanti tative resistance to SMV can well co nt rol the effects of SMV in the f ield as i t isclose to the qualitative resistance .
