According to results of reciprocal crossing between L. davidii and ‘Conception’, flower color of F 1 appears nearer to that of each male parent but they seemed to be influenced by L. davidii which has side-facing flower position. The characteristic traits of F 1 hybrids obtained from the cross between ‘Tresor’ and ‘Black Out’ is related to female parent ‘Tresor’. Whereas in a cross between ‘Navidad’ and ‘Hironde’, a progeny 122611-4 has the petal spot characteristic similar to the female Asiatic hybrid ‘Navidad’ and male parent ‘Gironde’ influence on the petal color. F 1 hybrid cross ‘Gironde × Red Sensation’ showed parental flower color expression contribution. In addition ‘Gironde’ as parent contributed extensively in imparting flower color in the resulting hybrids. In the above statements, F 1 progenies were more than 40cm in height and the plant height of their parents was over 70cm. Therefore, it is considered that their F 1 progenies are not short if parents have a long plant height. In ‘Kotnali × Tiny Bee’ progenies, 112061-1 progeny expressed orange flower color similar to female while 112061-2 showed yellow flower color same as male. Plant height was 27.7cm and 22.4cm close to 35.0cm of male parent ‘Tiny Bee’. F 1 hybrid of ‘Matrix × Holebibi’ expressed three flower color all of parents. It was dwarf and distinguishable as compared to parental phenotype. Therefore, it is concluded that for potted lily flower development carrying dwarf plant height and intermediate morphological traits Asiatic hybrids plays an important role such as ‘Tiny Bee’ and ‘Matrix’.","PeriodicalId":448090,"journal":{"name":"Korean Journal of Breeding","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122320834","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}

By each component, malonylgenistin content ranged from 99.2 μg/g to 1149.1 μg/g with the highest average of 390.0 μg/g, and glycitein content ranged from 0.1 μg/g to 2.4 μg/g with the lowest average of 0.8 μg/g. Among composition groups, the aglycone group contents ranged from 2.2 μg/g to 33.1 μg/g with the lowest average of 10.0 μg/g, and glucoside group contents ranged from 36.9 μg/g to 801.8 μg/g with an average of 202.4 μg/g.

Total of 21 agronomic and palatability traits were investigated over two locations in 2016. There was a significant hybrid by location interaction found in plant height, ear height, number of tillers/plant, per ear weight, ear tip filling, ear commercial value and sweetness when four additional check cultivars were included in the analyses. A significant general combining ability by location interaction was found in ear height, number of tillers/plant, per ear weight, ear length and sweetness while ear width, ear commercial value and sweetness were significant for specific combining ability by location interaction. Sweetness was found significant for both interactions. The first and fourth inbred lines had the most number of traits with good estimate of general combining ability. The first inbred is expected to improve days to tasseling, anthesis silking interval, ear width, ear circumference and sweetness while decreasing husk cover in a hybrid combination. The fourth inbred line would improve days to tasseling, days to silking, plant height, ear height, per ear weight and ear length but ears would be a bit tougher than the average. A total of 19 traits had higher variance of general combining ability than that of specific combining ability. Husk cover was 12.1 times higher.

The stability and uniformity of the cultivar was confirmed through the first and second characteristics tests in 2007 and 2008 and named as 'SM 7661'. SM 7661 produces dark red (RHS#185B) flowers of round shape and spreading mini type with size of 5.7 and 5.8cm in flower length and width, respectively. SM 7661 is regarded as raceme flower type with many flowers and good volume and suitable for small flower pot market.

In this research, open-source database information of Arabidopsis thaliana was adapted to determine root-specific expressed promoter region. A total seven sequences that might function as a root-specific promoter element were initially isolated from Arabidopsis genomic DNA. Then seven promoters were cloned into pBGWFS7 in which β -glucuronidase ( gus ) and green fluorescent protein (gfp) genes were linked. The GUS activities were measured in different tissues of transgenic Arabidopsis by both histochemical GUS staining and fluorescent 4 methylumbelliferyl β -D-glucuronide (MUG) assay. To confirm root-specific expression, GFP-confocal microscope analysis was conducted in Arabidopsis transgenic plant. As a result, the five promoters showed strong GUS activity in the root tissue as compared with the CaMV35S promoter. To test crop application availability as a root-specific promoter, seven promoters were introduced into tomato plants and confirmed transient expression using Agrobacterium rhizogenesis ARqua1 root-nodule inducible strain. Two promoters showed that gus genes were specifically expressed in roots of transgenic tomato plant. Taken together, the novel seven promoters showed specific activity in root suggesting that it is applicable in crop improvement.","PeriodicalId":448090,"journal":{"name":"Korean Journal of Breeding","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128790544","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}
