Abstract

Out of Sixty germplasms screened against false smut of rice, twenty nine viz., IET-16295, IET-16298, IET-16303, IET-15836, IET-15862, IET-14807, IET-15295, IET-15296, IET-15298, IET-15299, IET-15314, IET-15337, IET-15399, IET-10664, IET-15358, IET-15266, IET-15267, IET-16444, IET-16403, IET-16439,IET-16434, IET-16435, IET-16437, IET-15163, IET-15924, IET-15928, IET-15941, IET-15948 and IET-15949 were found free from false smut. Viability test of propagules revealed that the germination percentage of propagules decreased with the increase in depth of soil and length of storage. Also the propagules were more viable under laboratory condition than field condition where temperature was not controlled.
水稻不同基因型防治黑穗病的研究
经筛选的60份水稻假黑穗病防治材料中,29份无假黑穗病,即:IET-16295、IET-16298、IET-16303、IET-15836、IET-15862、IET-14807、IET-15295、IET-15296、IET-15296、IET-15314、IET-15337、IET-15399、IET-10664、IET-15358、IET-15266、IET-16444、IET-16403、IET-16439、IET-16434、IET-16437、IET-15924、IET-15928、IET-15941、IET-15948和IET-15949。繁殖体活力试验表明,随着土壤深度和贮藏时间的增加,繁殖体的发芽率降低。在实验室条件下繁殖体的存活率高于不控制温度的田间条件。
