莲藕是一种繁殖能力很强的植物。它可以采用无性繁殖──用芽繁地可以采用有性繁殖──用莲子繁殖。根据莲的繁殖的多样性及其繁殖器官上的特殊性，可以采用多种途径来进行莲藕品种的改良工作。（1）从自然混杂群体中单株东选育种。（2）从顶芽繁殖后代中选育。（3）从自然杂交莲子实生苗后代选育。（4）人工杂交选育新品系。由于莲藕采用人工杂交后，可以用无性繁殖方式，把杂交的优势固定下来，不需要多代自交纯化或者年年进行杂交制种，所以这将是一项行之有效的育种途径。文中并介绍了杂交后代F1代的性状表现，以及所选出的6个新品种（系）。
Lotus is a highly reproductive plant. It can be used for asexual reproduction ─ ─ can be used to reproduce the sexual reproduction multiply - lotus breeding. According to lotus multiplication and reproductive organ specificity, there are many ways to improve lotus root varieties. (1) Single plantation breeding from natural mixed populations. (2) breeding from the top bud breeding progenies. (3) from natural hybrid lotus seedlings offspring breeding. (4) Artificial hybrid breeding new line. As the lotus root artificial hybridization, you can use asexual reproduction, the advantages of hybrid immobility, do not need multi-generation self-purification or annual hybrid seed, it will be an effective breeding methods. In this paper, the F1 generation performance of F1 progenies and introduced 6 new varieties (lines) were introduced.
