     However, there is a debate on the chromosomal position of the Pii gene, because it was originally mapped on chromosome 6, but recent work showed it might be located on chromosome 9. To determine the chromosomal location of the Pi15 gene, a linkage analysis using molecular markers was performed in a F2 mapping population consisting of 15 resistant and 141 susceptible plants through bulked-segregant analysis (BSA) in combination with recessive-class analysis (RCA).

Using the joint scaling test, the genetic model and the gene effects ofresistance to scab were analysed in the parents P_1 and P_2, the progeniesF_1, F_2and the two backcrossed B_1and B_2 of Wang-Shui-Bai (WSB) x ChineseSpring (CS). The number of genes controlling resistance to scab was estima-ted with the F_2and the B_1, B_2 and the chromosomal location of these resist-ance genes is determined by monosomic analysis. Two methods of inoculationwere used. Glumes-clipping in the field was done by dipping...

Using the joint scaling test, the genetic model and the gene effects ofresistance to scab were analysed in the parents P_1 and P_2, the progeniesF_1, F_2and the two backcrossed B_1and B_2 of Wang-Shui-Bai (WSB) x ChineseSpring (CS). The number of genes controlling resistance to scab was estima-ted with the F_2and the B_1, B_2 and the chromosomal location of these resist-ance genes is determined by monosomic analysis. Two methods of inoculationwere used. Glumes-clipping in the field was done by dipping a pair ofscissors in the conidial suspension of Gibberell a Zeae, then cutting off asmall portion of the upper part of one of the glumes in the middle of thespike so as to enable a small drop of inoculum to drip into the floret.Individual-floret-injecting method in the laboratory was done by injectinginoculum into individual florets in the middle of the excised wheat spike whichwas placed in a bottle with clear water. Monosomic or disomic plants wereidentified by mitosis and meiosis observations. The results showed that theresistance to scab in the wheat variety seemed to be a quantitative charactercontrolled by nuclear genes. The additive-dominance model proved to besatisfactory in explaining the gnetic differences for the trait. There mightbe 5-6 genes for resistance in WSB. They were respectively located in 4A,5A, 7A, 7B and 4D chromosomes.

本文应用常规分析法研究了抗病品种望水白与感病品种中国春正反交F_1代赤霉病病小穗率的差异,用联合尺度测验分析了该组合的P_1、P_2、F_1、F_2、B_1和B_2世代抗赤霉病性的遗传模式及基因效应,估算了抗赤霉病性的基因数目。并用单体分析对望水白的抗扩展基因进行了染色体定位。全部抗性鉴定的材料采用田间剪颖滴菌接种,鉴定其抗赤霉病性,单体分析的F_2代还用了离体水培单花注射接种法。结果表明:小麦品种的抗赤霉病性是受细胞核基因控制的数量性状,有5-6对基因控制望水自的抗扩展性,分别定位在4A、5A、7A、7B和4D5条染色体上。2D染色体上的基因的作用还有待于进一步研究。望水白与苏麦3号属于不同的赤霉病抗源。

The chromosomal locations of crossahility genes of Chinese Spring and relationship between the crossability genes and Tai-gu dominant male sterile gene Ta_1 were studied by using crosses between Chinese Spring-Cheyenne disomic substitution lines, nullitetra lines of homoeologous group 5 of Chinese Spring、Chinese Spring、Cheyenne、Ta_1 Chinese Spring and rye cultivar Lanzhou in environment of Beijing. For the first time, the results indicated that there were some crossability genes (kr) with rye in chromosome 2B、6D、7B in Chinese Spring, except crossability genes in chromosome 1A、5B、5A、5D、7D. The results also indicated that there was no interference between gene Ta_1 and crossability genes (kr). So they can independentlly express when they are in a plant. In the environment of Beijing, the kr genes express easily in Chinese Spring.

Chromosomal location of the photoperiod sensitive male genic sterile gene ms~h inNonkeng 58s were carried out by use of Marker Gene mothed. The results indicated thatgene ms~h showed independent of 27 marker genes belonging to the 11 Linkage groupsin rice plants respectively, but the linkage relation between gene ms~h and markergene d-1 belonging to Linkage Group Ⅵ+Ⅸ was detected, and the recombination valuebetween gene ms~h and marker gene d-1 was estimated at 28.41+3.94% from the se-gregations in F_2...

Chromosomal location of the photoperiod sensitive male genic sterile gene ms~h inNonkeng 58s were carried out by use of Marker Gene mothed. The results indicated thatgene ms~h showed independent of 27 marker genes belonging to the 11 Linkage groupsin rice plants respectively, but the linkage relation between gene ms~h and markergene d-1 belonging to Linkage Group Ⅵ+Ⅸ was detected, and the recombination valuebetween gene ms~h and marker gene d-1 was estimated at 28.41+3.94% from the se-gregations in F_2 by the method of maximum likelihood (Hanson and kramer 1950).From the resuters, It was concluded that the gene ms~h for photoperiod sensitive malegenic sterile was on Nishimura's chromosome 2.

本研究用标记基因法对水稻农垦58S光敏感雄性不育基因进行染色体定位,结果表明光敏感雄性不育基因ms~(ph)分别与属于水稻连锁群Ⅰ等11个不同连锁群的U-1等28个标记基因表现为独立遗传,而与属于Ⅵ+Ⅸ连锁群的标记基因d-1连锁,估算二者之间的重组值为28.41±3.94%。推断光敏感雄性不育基因ms~(ph)位于西村氏的第二染色体上。
