甜瓜种子体细胞胚胎发生在18个品种间存在显著差异，特别是产生大量体细胞胚胎的品种‘Earl’‘和’Barnett‘。F1种子是通过品种间的正反交获得的。有些品系产生了大量的体细胞胚胎，而另一些品系则没有或表现出较差的胚性反应。大多数F1种子形成了体细胞胚胎。体细胞胚胎发生频率低于潜力最高的亲本。体细胞胚胎发生频率从反应较好的品种转移到反应较差的品种。体细胞胚胎发生的遗传方式很难确定，因为F_2种子体细胞胚胎发生的范围差异很大，而且在某些组合中存在细胞质效应。
Significant differences in somatic embryogenesis from melon seeds were observed among 18 cultivars; especially, cultivars 'Earl's Favorite' and 'Barnett' which produced a large number of somatic embryos. F1 seeds were obtained by reciprocal crosses between cultivars. Some lines produced a large number of somatic embryos whereas others showed no or poor embryogenic response. Most of the F1 seeds formed somatic embryos. The frequency of somatic embryogenesis decreased as compared to the parents with the highest potential. Transfer of the frequency of somatic embryogenesis from superior responding cultivars to inferior cultivars was proved. It was difficult to determine the mode of inheritance of somatic embryogenesis because there was a large variation in the range of somatic embryogenesis from F2 seeds, and cytoplasmic effect was recognized in certain combinations.
