The operation of these recessive genes influencing crossability with rye was similar to that of hexaploid common wheat.

通过与六倍体普通小麦相比较，结果表明四倍体小麦的可杂交性系统与六倍体小麦的可杂交性系统的作用方式是类似的。

CIMMYT synthetic hexaploid wheats were employed to cross with rye for evaluating the crossability of SHWs and screening SHWs with high crossability for distant cross. Great variation of the seed set percentage was observed among 102 SHWs ranged from 0% to 72.49%. Of 102 SHWs, 11 ones possessed the crossability higher than 50%, and one (YAR/Aegilops tauschii 518) had a similar crossability as Chinese Spring.

利用102份从CIMMYT引进的人工合成六倍体小麦与黑麦杂交，分析了人工合成六倍体小麦的可杂交性，结果表明：人工合成小麦的可杂交能力变异很大，从0%~72.49%；其中有11份人工合成小麦的可杂交率超过50%以上，1份人工合成小麦YAR/Aegilops tauschii 518的杂交结实率达到72.49%，与中国春相似。

The distribution of hybrid chlorosis Ch1 gene and the T-type cytoplasm fertility restoring genes in Chinese endemic wheats were studied using the testors QA1104 (T-type cytoplasm sterile line, with hybrid chlorosis Ch2 gene) and Khapli emmer (with hybrid chlorosis Ch1 gene).

The results showed that the number of chromosome, which was from the cultured seedlings of meristem tip and the rank seedlings of meristem tip, was not altered, both the number were 2n=16,the hereditary stability of callus and regeneration plant was poor; and the variation percentage of chromosome in callus was 43.4%, among which haploid accounted for 6.7%, triploid accounted for 2.5%,tetraploid accounted for 10%,pentaploid accounted for 4.2%,hexaploid accounted for 3.3%,septuploid accounted for 4.2%,octoploid accounted for 3.3%,dysploid accounted for 9.2%;the chromosome variation percentage of differentiation seedlings derived from callus was11.7%,among which haploid was 6.7%,triploid accounted for 1.7%,tetraploid was 3.3%.

结果表明，茎尖分生组织培养的幼苗及丛生苗遗传稳定，其染色体未发生倍性变异，均为2n=16；愈伤组织及其再生苗遗传稳定性较差，愈伤组织染色体数变异率为43.4%，其中单倍体占6.7%、三倍体占2.5%、四倍体占10%、五倍体占4.2%、六倍体占3.3%、七倍体占4.2%、八倍体占3.3%、非整倍体占9.2%；愈伤组织分化苗染色体变异率为11.7%，其中单倍体占6.7%，三倍体占1.7%，四倍体占3.3%。

AI1 of our common or bread wheats, whether winter or spring varieties, are hexaploids.

我们的普通小麦，不论是冬性品种还是春性品种，全都是六倍体。

"Wheats are called diploids when they have seven chromosomes, tetraploids when they have fourteen , and hexaploids when they have twenty-one."

其性细胞具有7条染色体的小麦称为二倍体；具有14条染色体的称为四倍体；具有21条的称为六倍体。

Thus, the meiotic chromosome cofigurations showed that the tetraploids and hexaploids in C.reticulata allopolyploids, and the appearance of a few tetravalents in some populations might indicatehomology of chromosomes in different genomes to some extent.

根据减数分裂的构型，我们认为，四倍体和六倍体分别为异源四倍体和异源六倍体，少数四价体的存在表明染色体有部分同源性。

Most primers amplified same bands in diploids, tetraploids and hexaploids. It suggest that D and AB genomes have high homology and D genomes be successfully transferred from diploid to hexaploid.

从供试的绝大多数引物均能在不同倍性小麦中扩增出相同的条带证明了D染色体组和AB染色体组间存在着很高的同源性以及利用二倍体和四倍体小麦杂交人工合成六倍体小麦的真实性。
