3批92粒阳性反应种子检测说明,绝大多数种子子叶和胚带花生条纹病毒(PStV),仅有收获前摘取2粒未成熟种子种皮带毒。PStV种传率与品种、病毒侵染时期密切相关。参试17份花生品种和材料中,种传率最高为20.6％,最低1％。珍珠豆型花生品种种传率明显高于普通型和其他类型花生品种。早期感病花生PStV种传率高,花针期以后感病种传率明显下降。小粒种子PStV种传率高于大粒种子。
Three batches of 92 positive reaction seeds showed that the majority of seed cotyledons and peanut streak virus (PStV) were harvested and only two immature seeds were harvested before harvest. PStV species transmission rate and variety, closely related to the period of virus infection. Among the 17 peanut cultivars and materials tested, the highest germination rate was 20.6% and the lowest was 1%. Pear-bean peanut variety transmission rate was significantly higher than the ordinary type and other types of peanut varieties. The PStV transmission rate of early susceptible peanut was high, and the transmission rate of susceptible seed decreased significantly after flowering. Small seed PStV seed transmission rate higher than the large seed.
