The morphological characteristics, such as the leaf, flower, and fruit, and random amplified polymorphic DNA (RAPD) analysis revealed that ‘07RUBIXP01’ was an interspecific hybrid. Although ‘07RUBIXP01’ had small thorns, it showed vigorous growth in the warm environment and had a significantly larger fruit compared with the parents. Also, ‘07RUBIXP01’ showed values intermediate between those of the parents for total polyphenol, anthocyanin, and ellagitannin contents. In particular, it showed an ellagitannin content that was about four times higher than that of ‘Indian Summer’. In sugar and organic acid analyses, a higher sugar acid ratio was noted compared with the parents. ‘07RUBIXP01’ was registered as a new variety in 2012 (variety registration no. 21801), and it would be a useful raspberry for growing in warm regions of Japan.","PeriodicalId":114914,"journal":{"name":"Horticultural Research (japan)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127754362","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Perviridis Group) and arugula (Eruca sativa Mill.), both belonging to the Brassicaceae family, followed by ovule culture. The morphological characteristics of the hybrid were as follows: inflorescences and leaf blades were intermediate between the parents, while the sequence of the placenta was B. rapa L. type, and the shape of the stalk leaf base was E. sativa Mill. type. GISH analysis by probing with total genomic DNA of either B. rapa L. or E. sativa Mill. confirmed the hybridity of the amphihaploid. Analysis of the secondary metabolites revealed that the crossing hybrid contained all the glucosinolates and isothiocyanates that were found in both species, in addition to the erucin precursor (4-methylthiobutyl-GSL: Glucoerucin) and sulforaphane precursor (4-methylsulfinylbutyl-GSL: Glucoraphanin), both specific to arugula. These results demonstrate that intergeneric crosses between B. rapa L. and E. sativa Mill. are expected to expand genetic variation and lead to the successful breeding of new value-added tender greens that meet consumer needs.","PeriodicalId":114914,"journal":{"name":"Horticultural Research (japan)","volume":"117 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116184627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
