病毒株主要为汉坦病毒 Hantan virus ; HV
变异系数较小，即改良潜力小的性状为株高、穗长、主穗小穗数、有效小穗数。
The traits with low CV value are plant height, ear length, number of spikelets, available spikelets which had low improvement potential.
株高、抽穗期、主穗长、结实率、剑叶宽、粒长、粒宽和粒形以基因加性效应的作用为主。
Additive effects has the predominant role for plant height, days to flowering, panicle length, flag-leaf width, percentage of fulled grains, grain length, grain width and L/Wratio of grain.
性状变异系数最大是单株分蘖数，其后依次为单株粒重和主穗粒重，最小的为株高；
The variation coefficient of the tillering number per plant was the maximal, while grain weight per plant and the main spike grain weight was the next.
