Abstract

The F2 progeny of a cross between a chromosome 2 multiple marker stock and an adapted cultivar of barley were analyzed for four morphological markers and electrophoretic patterns of eight leaf isozymes. The Idh-2 locus was linked to the Per-5 locus (27.96 +/- 5.07 cM) and to the e locus (10.26 +/- 3.13 cM). Also, the Per-5 and e loci were located on the short arm of chromosome 2. In addition Idh-2 was also located on barley chromosome 2 and was linked to the v locus (13.18 +/- 3.56 cM), which is located on the long arm of chromosome 2. Two other marker genes, li and wst,,B, were linked (26.50 +/- 5.24 cM) on chromosome 2 but segregate independently of the other loci evaluated.

摘要

对2号染色体多标记品系与一个适应性大麦栽培品种杂交产生的F2后代进行了分析，检测了4种形态标记和8种叶片同工酶的电泳图谱。异柠檬酸脱氢酶-2（Idh-2）基因座与过氧化物酶-5（Per-5）基因座（27.96±5.07厘摩）以及e基因座（10.26±3.13厘摩）连锁。此外，Per-5和e基因座位于2号染色体的短臂上。另外，Idh-2也位于大麦2号染色体上，并且与v基因座（13.18±3.56厘摩）连锁，v基因座位于2号染色体的长臂上。另外两个标记基因，li和wst，B，在2号染色体上连锁（26.50±5.24厘摩），但与所评估的其他基因座独立分离。
