黑穗醋栗品种亲缘关系的ISSR分析 总被引：4，自引：1，他引：3
采用ISSR标记技术对39个黑穗醋栗品种的亲缘关系进行分析。结果表明：13条ISSR引物扩增的总带数（A）从3到11条不等,平均扩增出6.77条带,平均多态性带百分比（P）为64.37%。聚类分析显示,在相似性系数为0.8496处将39个黑穗醋栗品种分为5组。第Ⅰ组包含8个起源国家的品种,说明世界各国之间基因交流较为频繁。‘Ben Lomond’和‘Kantata’同其他品种的遗传距离较远,两者又有诸多优良农艺性状,可作为黑穗醋栗的优良育种材料。 相似文献

SummaryThe in-vitro multiplication rates of fourteen black currant (Ribes nigrum) cultivars from a range of geographical origins were compared. Shoot tips and axillary buds were cultured for 21 days in a medium supplemented with 2.2 mg l?1 6-benzylaminopurine. The highest shoot multiplication rate achieved was by cv. Ben Lomond, where the mean rate was 3.53 shoots from a single initial expiant. Mean rates between 1.50 and 3.33 were obtained from other cultivars. The results are discussed in relation to the parentage of each cultivar. 相似文献

从蔓越橘（Vaccinium macrocarpon Ait.）品种‘Ben Lear’基因组序列中发掘了398 014 bp的长末端重复序列反转录转座子（LTR-RT）,占整个基因组序列的11.17%;鉴别出228条Ty1-Copia家族成员和137条Ty3-Gypsy家族成员。以45个越橘（Vaccinium spp.）品种和1个蔓越橘品种为材料,从53对基于LTR-RT插入位点开发的引物中筛选出17对多态性引物,建立了越橘品种的LTR-RT插入多态性（RBIP）分子标记。使用RBIP标记对46个品种进行了亲缘关系分析和分子身份证构建,其中多态性最高的位点是Vmrg1,最低的位点是Vmrg14。其PCR产物的大小变化范围为200 ~ 463 bp,最小长度片段和最大长度片段分别出现在位点Vmrc19和Vmrc3。46个品种基于遗传距离聚为6组,组Ⅰ包括3个北高丛越橘品种,蔓越橘单独聚为组Ⅵ,其他4组中北高丛越橘、南高丛越橘或兔眼越橘混杂在一起。利用17个位点组成的“1”、“0”字符串构建了45份越橘品种和1份蔓越橘品种的唯一分子身份证,为越橘品种的鉴别提供了参考。 相似文献

Temperate-zone crops require a period of winter chilling to terminate dormancy and ensure adequate bud break the following spring. The exact chilling requirement of blackcurrant (Ribes nigrum), a commercially important crop in northern Europe, is relatively unknown. Chill unit models have been successfully utilized to determine the optimum chilling temperature of a range of crops, with one chill unit equating to 1 h exposure to the optimum temperature for chill satisfaction. Two-year-old R. nigrum plants of the cultivars ‘Ben Gairn’, ‘Ben Hope’ and ‘Ben Tirran’ were exposed to temperatures of −10.1 °C, −3.4 °C, 0.1 °C, 1.5 °C, 2.1 °C, 3.4 °C or 8.9 °C (±0.7 °C) for durations of 0, 2, 4, 6, 8 or 10 weeks and multiple regression analyses used to determine the optimum temperature for chill satisfaction. 相似文献

Inter-Simple Sequence Repeat (ISSR) markers were used for the assessment of genetic diversity among walnut (Juglans regia L.) selections from Greek native populations in comparison to internationally cultivated walnut genotypes. Similarity coefficient values from 0.13 to 0.93 (with an average of 0.48) were found among the 56 accessions examined, which indicated the presence of a high degree of genetic variability. Most international cultivars were grouped together while most Greek native populations could not be placed into a distinct group. The Greek native population genotypes were found more diverse than the international cultivars. The mean similarity coefficient values for the former and latter were 0.44 and 0.56, respectively. In the cultivar group, two subgroups were distinguished; one consisted of genotypes involving ‘Payne’ and the other ‘Franquette’ in their pedigrees. Some cultivars and populations could not be grouped according to their pedigrees or collection area. Analysis of molecular variance (AMOVA) revealed that a larger part of the genetic variation exists among Greek walnut populations within a collection region (89%) than among the regions (11%). The pairwise regional PhiPT values indicated that the most geographically distant regions are the most genetically differentiated. The high variability existing in the Greek germplasm in combination with their valuable agro-morphological traits suggested that it would be beneficial to utilize this native germplasm pool in walnut breeding programs and germplasm management activities to maximize genetic diversity in cultivated walnut. 相似文献
