从Ｈ１花药单倍体试管苗基部，取尚未分化绿苗的胚性愈伤组织建立的体细胞无性系，获得４丛Ｒ１结实株系。从田间Ｒ２的观察中发现，Ｒ１的４株后代中有１株４个穗繁衍的８６个单株发生了变异，Ｒ２的株系变异率为２５％。经过这株变异的Ｒ２、Ｒ３的株高连续观察发现：株高变异范围均很大，并有超亲现象，Ｒ２的变异大于Ｒ３；穗系间和穗系内的变异均极显著，穗系间变异大于穗系内变异；Ｒ３有８．１４％的株系已稳定；Ｒ２和Ｒ３的株高呈显著正相关。 From the base of H1 anther haploid tube plantlets, the somatic clones established by the embryogenic callus of undifferentiated green plantlets were obtained, and four Cong R1-bearing lines were obtained. From the observation of field R2, we found that one of the four offspring of R1 had mutation in the 86 individual plants of 4 ears, and the mutation rate of R2 was 25%. After continuous variation of plant height of R2 and R3, we found that the range of plant height variation is very large and there is super-progeny phenomenon, the variation of R2 is greater than that of R3; the variation within panicle and panicle is extremely significant, panicle The intraspecific variation was greater than that in the panicle; 8.14% of the strains in R3 were stable; the R2 and R3 plant height were significantly and positively correlated.
