영문 초록

Transmission rate of extra telocentric chromosomes and some agronomic characteristics were studied at early leaf stage in 11 monotelotrisomics and 4 ditelotrisomics, compared with each their sist-diploids of barley. Mean transmission rate of 11 monotelotrisomics was 27.5%, but that of 4 ditelotrisomics was 20.2% in next selfing generation. Observed the mitosis of Triplo 3S and 5S, 2n=14+2 telos and 2n=15 plants were found. Besides, in ditelotrisomics of Triplo 5S and 7S, 2n=15+1 fragment were found also. On the other hands, compared with sist-diploids, at eraly leaf stage, leaf color of Triplo 1L, 2L and 2S were dark green, and those leaf shapes of Triplo 1L and 2L were very long and narrow. In tillers of main stem, Triplo 1L, 1S and 2L were more than each their sistdiploids. But Triplo 1L and 2L were drooping shape in plant type, while the others wer erect or semierect. Root-system of Triplo 1L and 2L were well developed, long and more, but Triplo 4L and 7S were very poor. Ditelotrisomic 5S and 7S were almost the same in plant type, leaf shape and leaf color to each monotelotrisomic ones.
