在毛主席的革命路线指引下,我国的花生育种工作,实行专业研究与群选群育相结合,正在广泛而深入的开展起来。除了进行常规育种外还相继采用了辐射育种、多倍体、单倍体等方法。这样以来,花生的染色体数目便引起了育种工作者的注意。从我们看到的国内外资料,花生染色体数有2n=20和2n=40的两种不同说法,其染色体数目的差异与类型与果实大小有直接关系。为了验证花生染色体竟究是多

Guided by Chairman Mao’s revolutionary line, the peanut breeding work in our country is being extensively and thoroughly carried out through a combination of professional research and mass group education. In addition to conventional breeding also have adopted radiation breeding, polyploid, haploid and other methods. Since then, the number of chromosomes in peanuts has drawn the attention of breeders. From the information we have seen at home and abroad, the number of peanut chromosomes is 2n = 20 and 2n = 40 in two different ways. The difference in chromosome number is directly related to the type and fruit size. In order to verify the peanut chromosome is actually more
