The triploid and tetraploid clones of the silkworm (Bombux mori L.) are capable to be reproduced for a long time by means of thermal parthenogenesis. The activated eggs are pigmented in 80-99%. The hatching of larvae in triploid clones amounts to 20% and in tetraploid ones to 25-30%. The pigmentation of eggs and hatching of larvae greatly vary in different years: 47 to 100% and 0 to 73%, resp. In this respect, the polyploid clones are similar to those diploid ones which are characterized by the low percentage of complete parthenogenesis. The causes for the variability of parthenogenesis indices in the polyploid clones are discussed.
家蚕（Bombux mori L.）的三倍体和四倍体克隆能够通过热孤雌生殖长期繁殖。活化卵的色素沉着率为80 - 99%。三倍体克隆幼虫的孵化率为20%，四倍体克隆幼虫的孵化率为25 - 30%。卵的色素沉着和幼虫的孵化率在不同年份有很大差异，分别为47%至100%和0至73%。在这方面，多倍体克隆与那些以完全孤雌生殖比例低为特征的二倍体克隆相似。文中讨论了多倍体克隆中孤雌生殖指数变异性的原因。
