Discussions are given of the fate of Ms2 during translocation in the hexoploid triticale, the exchange of the names for 4A and 4B chromosomes in common wheat and the possible expoitation of the new locus Ms2 (4BS), and the following speculations are made: In geneic genes of allopolyploid organisms the donor chromosomes tend to be intergenomically translocated to their phylogically and evolutionarily close chromosomes with the same order number and the same arm; it is cofirmed that the 7th International Conference of Wheat Genetics was right to exchange the names between chromosomes 4A and 4B of common wheat in 1988; and as a new genetic marker and a breeding tool for all the chromosome B-carrying species in the tribe of Tritceae, Ms2 (4BS) may have wide application in building and expanding the gene pool of germplasm resources of various species of wheat.
对 Ms2基因在六倍体小黑麦与原太谷核不育小麦远缘杂交中易位时的走向,普通小麦4A与4B染色体的互换更名以及 Ms2(4BS)新位点的开发利用进行了讨论:认为异源多倍体生物核基因的组间易位倾向于从供体染色体向进化亲缘关系较密切,且染色体序数与染色体臂相同的部分同源染色体易位;1988年第7届国际小麦遗传学会对普通小麦4A与4B染色体的互换更名是正确的; Ms2(4BS)作为一个新型的遗传标记,作为小麦族内所有携带B染色体组的物种的育种工具和在拓建各类小麦种质资源的基因库等方面均有广泛的用途。

Since curly leaf hybrid could be recognized at early stage,and displayedobvious dwarfness,choosing"Zha′ai 76"as paternal parent not only raised thehybrid-selecting efficiency from the pollinated progenies,but also raised thebreeding efficiency of apomctc dwarf roostock of apple.
鉴别宽叶型杂种较难、需时较长(2-3年生时)并需与染色体倍性鉴定法相结合,因其形态变化较小而生长势又与平邑甜茶无融合生殖苗无明显差异;鉴别光叶型杂种因父本染色体组的影响加大而从形态上容易些,但也需过氧化物同工酶法或染色体倍性鉴定法相配合;皱叶型杂种因在苗期刚出1-2片真叶时就表现明显的标志性状、能从叶片形态上准确鉴别出来,毋须染色体倍性鉴定等复杂方法;因皱叶型杂种能早期鉴别,又表现明显的矮生性,因而选用"扎矮76"做父本不仅大大提高了平邑甜茶授粉后代中选择杂种的效率,而且提高了苹果无融合生殖型实生矮砧育种的效率。

It indicated that a considerable degree of genetic differertiation has taken place in the A and B genomes of two species during evolution from wild emmer to common wheat.2 The similarities co-efficiency of A genome of common wheat and wild emmer was slightly higher than that of B genome.
野生二粒小麦与普通小麦A染色体组的遗传相似性高于两物种B染色体组的遗传相似性,从而说明小麦的不同染色体组在进化过程中的遗传速率或者说进化中的稳定程度是不同的。

DNA C-values might be one of important indices in the evaluation of angiospermous invasiveness. To test this viewpoint, we compared DNA 1C-values and basic genome sizes in 3,676 angiosperms. The results suggest that:(1) the two nuclear values vary greatly among different groups, e.g., significantly higher in herbs than in trees, in monocots than in dicots, in perennials than in non-perennials;(2) the two nuclear values both have significant effects on plant invasiveness, especially in herbs, dicots, monocots, perennials, non-perennials, diploids, polyploids, Compositae, and Poaceae, while not significant in trees and Fabaceae.
DNA C值与被子植物入侵性密切相关,为考察应用DNA C值评估被子植物入侵性的可靠性和局限性,我们统计分析了全世界范围内3676种被子植物的DNA 1C值(配子未发生DNA复制时的染色体DNA含量)及基因组大小(单个染色体组的DNA 含量),结果表明:1)DNA 1C值和基因组大小在被子植物不同类群中差异极大,例如在草本植物中显著高于木本植物,单子叶植物显著高于双子叶植物,多年生植物显著高于非多年生植物;2)两项指标都与被子植物入侵性显著负相关,尤其是在草本植物、双子叶植物、单子叶植物、多年生植物、非多年生植物、二倍体、多倍体、菊科和禾本科中,然而在木本植物、豆科植物中其与植物入侵性无显著关系。
