Development of each alien species chromosome substitution line in upland cotton involves three stages:(a) development of the respective TM-1-like hypoaneuploid stock,(b)use of the cytogenetic stock as recurrent parent in a recurrent backcrossing program to create a monosomic or monotelodisomic substitution stock,followed by(c)inbreeding to recover a euploid disomic substitution line.
再结合染色体置换系构建的过程,可以认为CSB14Sh确实为第14条染色体短臂的置换系。
A set of chromosome segment substitution lines (CSSLs),derived from Asominori/IR24 with Asominori as the recurrent parent,was planted and phenotyped for grain length (GL),grain width (GW) and length-width ratio (LWR) of milled rice in two successive years and four sites.
利用Asominori×IR2 4的染色体片段置换系 (CSSLs)群体 ,对稻米粒长、粒宽和长宽比进行连续两年及 4个地点的QTL表达稳定性分析。
Using an indica variety 93-11,a japonica variety Nipponbare and seven chromosome segment substitution lines(CSSLs)with a genetic background of 93-11 introgressed from Nipponbare as the materials,we investigated seed shattering with 153 simple sequence repeat(SSR)markers on rice chromosomes,the introgressed segment and the quantitative trait loci(QTL)for seed shattering.
以7个染色体片段置换系为材料,采用重叠群代换作图法对控制落粒性的2个主效QTL进行定位。
In the paper,with an indica variety 93-11,a japonica variety Nipponbare and 8 chromosome segment substitution lines(CSSLs) with the genetic background of 93-11 introgressed from Nipponbare as the materials,using 153 SSR markers distributed on 12 rice chromosomes,the substituted segment and the QTLs for grain shape were analyzed.
