用0．2％的秋水仙水溶液对10叶期左右的辣椒幼苗进行滴心处理，从其中一处理单株的自交后代中选出一棵四倍体单株。通过几年的繁殖和综合鉴定，目前已形成了稳定的辣椒四倍体系统，四倍体的主要特征特性表现为植株高大、叶片、花冠、花蕾明显大于原品种，果实短而粗；种子量较少，但子粒较大，小区产量不及原品种，但主要营养成分略高于原品种。用四倍体和二倍体进行杂交，其杂种一代表现基本无子。
The seedlings of peppers around 10 leaf stage were treated with 0.2% Dactylisols by dropping heart, and one tetraploid individual was selected from the selfed offspring of one of the treatments. After several years of breeding and comprehensive appraisal, it has formed a stable tetraploid system of pepper. The main characteristics of tetraploid plants are tall, leaves, corolla, buds are obviously larger than the original varieties, the fruit is short and thick; the amount of seeds Fewer, but larger seeds, cell yield less than the original breed, but the main nutrients slightly higher than the original breed. With tetraploid and diploid hybrids, the hybrid generation basically no child.
