用有性群体茶籽作辐射引变材料进行辐射引变,M_1代就出现大量变异,其中大部分是属于遗传上的分离,有些则是辐射引起的变异。茶树可以进行营养繁殖,当代一些有益的变异可以直接固定,但一些外形上难于观察的隐性突变性状,必须通过自交纯合,才能显现出来,再则,某些突变体也只能通过与一些优良品种(或品系)杂交才能被较好地利用。据联合国粮农组织和国际原子能机构所属的辐射与同位素在粮
Using sexual tea seed as a radiation-inducing material for radiation induction, a large amount of variation appeared in the M_1 generation, most of which were inherited genetic segregation, while others were caused by radiation. Tea trees can be vegetatively propagated, and some beneficial variations in the present age can be directly fixed. However, some recessive mutant traits that are difficult to observe in appearance must be revealed by self-fertilization and homozygosity, and some mutants can only be expressed through Some fine varieties (or lines) can be better utilized. According to the radiation and isotopes belonging to the UN Food and Agriculture Organization and the International Atomic Energy Agency
