1995~1996年试验结果表明,SC2053是一种高效小麦化学杀雄剂,可诱导相对雄性不育率达97.5%~100%。不同品种对SC2053的敏感程度不同。SC2053的最佳喷药期为小麦幼穗发育长度为0.5~1.2cm时,最佳用药剂量为0.5~0.7kg/hm2。SC2053可降低株高5cm左右,但对雌蕊等其他性状无明显副作用。在父母本行比为3:6时,相对异交结实率可达53.5%~67.8%,制种产量为1747.5~2049.0kg/hm2。
The results from 1995 to 1996 showed that SC2053 is a high efficient wheat chemical killing agent, which can induce relative male sterility rate of 97.5% -100%. Different varieties of different sensitivity to SC2053. The best spraying period of SC2053 is 0.5 ~ 0.7kg / hm2 when the young wheat is 0.5 ~ 1.2cm in length. SC2053 can reduce the height of about 5cm, but no other side effects of pistil and other traits. When the ratio of parents to parents is 3: 6, the relative outcrossing rate can reach 53.5% ~ 67.8% and the seed yield is 1747.5 ~ 2049.0kg / hm2.
