1.对15个属97个种、变种和40个杂种根南瓜的体细胞染色体进行了计数。杂种为文心兰联盟中的14种属组合。在物种中增加了新的编号（2n）：2n = 24、26、30、32、37、40、60、84、133和168（表1 - 3）。文心兰联盟的染色体基数可能是5和7.4。大多数杂交种的染色体数目都是双亲染色体数目之和，但也有一些杂交种没有（表4）。杂种中发现的染色体数目如下（表4）：2n = 28、32、34、40、41、42、44、49、50、56、58、59、60、61、76、80、84和112.6。可以对某些物种和杂交种进行染色体组型分析。通常只能看到缩窄，而不容易识别出trabants、刚毛等。
1. Somatic chromosomes were counted by the root squash in 15 genera, in which 97 species and varieties, and 40 hybrids are included. The hybrids are 14 kinds of genus combinations in the Oncidium alliance.2. New numbers (2n) were added in species: 2n=24, 26, 30, 32, 37, 40, 60, 84, 133 and 168 (Tables 1-3).3. The basic numbers of chromosomes in the Oncidium alliance may be 5 and 7.4. Most of the hybrids studied showed the sum of their parents' chromosome numbers though some hybrids have not (Table 4).5. The chromosome numbers found in the hybrids are as follows (Table 4): 2n=28, 32, 34, 40, 41, 42, 44, 49, 50, 56, 58, 59, 60, 61, 76, 80, 84 and 112.6. Karyotypes could be analysed in some species and hybrids. Generally only constrictions can be seen, and trabants, seta, etc. can not easily be recognized.
