Both \n randomly amplified polymorphic DNA (RAPD) and simple sequence repeat (SSR) \n markers were used to screen a population of 98 genotypes within the population plus the \n two parents, ‘Arapaho’ and ‘Prime-Jim’® (APF-12). RAPD analysis averaged 3.4 \n markers per primer, whereas SSR analysis yielded 3.0 markers per primer pair. \n Similarity coefficient derived from the Dice index averaged over all individuals was 63% \n for RAPD markers, 73% for SSR markers, and 66% for RAPD and SSR markers \n together. The average similarity coefficients ranged from a high of 72% to a low of 38% \n for RAPD markers, 80% to 57% for SSR markers, and 73% to 55% for both. \n Comparison of the parents indicated a similarity of 67% for RAPD markers, 62% for \n SSR markers, and 67% for both. This is similar to a previous study that reported the \n similarity coefficient at 66%. Although inbreeding exists within the population, the level \n of heterozygosity is high. Also, evidence of tetrasomic inheritance was uncovered within \n the molecular marker analysis. This population will be used to identify potential markers \n linked to both morphological traits of interest. Further genetic linkage analysis and \n mapping is needed to identify any putative markers","bbox":{"left":0.147059,"top":0.495788,"width":0.7051780000000001,"height":0.302636}},{"text":"Presenters: \n Chairs:","bbox":{"left":0.147059,"top":0.813803,"width":0.094922,"height":0.038787999999999934}},{"text":"Submit abstracts to Chair at meeting or email by date announced by Chair. \n Submit all the abstracts from your Section as a group to: \n Managing Editor, HortScience \n E-mail: ashs@ashs.org \n Deadline: Submit by March 1st","bbox":{"left":0.264706,"top":0.813667,"width":0.585981,"height":0.09096899999999997}}],"images_bbox":[],"images_bbox_not_text_overlap":[]}
