一对

Also some people slept in the small tents or mats… I took a photo for a old couple slept on the mats and a photo for an aged couple sat face to the sea, their leisure lookings let me envy, On the sea bank I had shot a phot with a old woman sitting and reading under a large banian, how nice where her' choice.

海边的人景我自然特别关心，你细细看来实在有趣极了：睡在海滩上的，游在海水中的，冲浪的，在海中打水球的，在沙滩打排球的，坐在海岸上的，还有的人晚上干脆就睡在小帐篷里或小席子上……我拍到了一对老年夫妇在席子上躺着的照片，还有一对老年夫妇面朝大海坐在那儿

It was showed that wheat gliadins were codominant and the female parent prevailed in F1; there were 9 bands segarated as a pair of gene, for example, Gli-23.2, 34.8, 40.2, 46.2, 71.5, 73.8, 13.9, 26.0, 50.0 and there were 9 bands separated as two pairs of genes in F2, in addition, Gli-17. 8 did not follow with any one of them.

结果表明，醇溶蛋白在F1代表现出共显性和倾母性遗传特点；F2代蛋白谱带发生分离，具体表现为：Gli-13.9、23.2、26.0、34.8、40.2、46.2、50.0、71.5、73.8等9个组分的分离符合一对基因的分离规律，而Gli-12.7、15.7、16.5、19.1、26.9、30.5、30.8、32.2、76.8等9个组分的分离符合两对基因的分离规律；Gli-17.8既不符合一对基因的分离规律，又不符合两对基因的分离规律。

The chromosomal constitution of 200 advanced lines from 1R monosomic addition lines between the wheat cultivar Mianyang11 (MY11) and different rye lines R3, R12, and Baili-rye was studied by the improved C-banding and A-PAGE method. The result showed that 45 lines were identified as 1RS/1BL translocation lines congruously by the two methods. But a line (843-1-1), originated from an 1R addition line of wheat cultivar MY11 and rye line R12, was identified as 1RS/1BL translocation line by C-banding and genomic in situ hybridization,but the secalin block from chromosome arm 1RS of rye was absent in the A-PAGE pattern of its seed proteins.

结果发现，在鉴定的200个株系中，有45个株系经C-带和A-PAGE检测均一致地发现它们含有一对1RS /1BL易位染色体，而一个株系843-1-1，C-带鉴定、原位杂交结果均证明它含有一对1RS/1BL易位染色体，但A-PAGE醇溶蛋白图谱却不具有黑麦1RS染色体臂的黑麦碱特征带，而表达出既不同于黑麦碱又不同于亲本绵阳11的醇溶蛋白带型。
