本文报道了花生属的栽培花生(6个品种)和两个野生种的核型,它们的核型公式如下:姜半、开封一撮秧、伏花生、白沙1016和西洋生均为2n=40=38m+2sm(SAT);四粒红为2n=40=38m(2SAT)+2sm(SAT);A.cardenasii 为 2n=20=18m+2sm(SAT);A.batizocoi 为2n=20=16m+4sm(2SAT)。最后,本文对栽培花生起源的有关问题进行了讨论。
The karyotypes of cultivated peanut (6 cultivars) and two wild species of peanut were reported in this paper. The karyotypes of the peanut cultivars were as follows: ginger half, Kaifeng one seedling, peanut, white sand 1016 and western born 2n = 40 = 2m = 20m + 2sm (SAT); 4n red is 2n = 40 = 38m (2SAT) + 2sm (SAT); A.cardenasii is 2n = 20 = 18m + + 4sm (2SAT). Finally, the paper discusses the origin of cultivated peanut.
