摘要：
The supernumerary spikelet (SS) character of bread wheat (Triticum aestivum L.) is an abnormal spike morphology expressing extra spikelets per spike. Chromosomal location of the genes for the SS character in the bread wheat line, Yupi Branching was determined by monosomic analysis. The normal-spiked bread wheat Chinese Spring monosomic series were used as testing lines. Data indicated that chromosomes 2D, 4A, 4B and 5A of bread wheat carry genes for SS character (bh genes). Among them, the gene on chromosome 2D has the strongest effect on the expression of the SS character. Comparison of disomic and monosomic plants in 2D, 4A, 4B and 5A F2 populations revealed that the bh genes are hemizygous-effective and dosage-independent. The F1 monosomic analysis showed that the bh genes of Yupi Branching are recessive.
