P-15 Characteristics of berry growth in tetraploid table grapes with different cracking susceptibilities in Korea H.-K. Lim*, I.-C. Son, S.-I. Oh, H.-S. Shin, D. Kim Dept. of Horticultural Science, Chungbuk National University, Cheongju, Korea *Corresponding author: lhkhg@hanmail.net Berry cracking is one of the most serious problems for high quality table grape cultivation using tetraploid cultivars in Korea. Berry cracking patterns and factors were investigated through growth characteristics and morphological observation of berry between two tetraploids (‘Fujiminori’ and ‘Kyoho’) and compared with diploid ‘Campbell Early’ which has different cracking susceptibility of berry. The stomata were scattered on ovary surface at full bloom stage and numbers of stomata were different: 16.5 in ‘Fujiminori’, 14.7 in ‘Kyoho’, and 9.95 in ‘Campbell Early’ and the stomata were scattered on ovary surface. T The numbers of stomata at the veraison stage, however, changed depending on location of berry to 9.8 (stylar end trisection), 6.2 (equatorial trisection), and 3.6 (stem end trisection) in ‘Fujiminori’ and 5.3, 7.7, and 1.7 in ‘Kyoho’, and 2.7, 3.9, and 3.2 in ‘Campbell Early’. As berry growth advanced, patterns of distributed stomata changed and were different in each cultivar. The berry cracking rate at veraison of ‘Fujiminori’ and ‘Kyoho’ was remarkably high, 13.2 and 7.0%, compared with 0.6% in ‘Campbell Early’. Berry cracking-sensitive ‘Fujiminori’ and ‘Kyoho’ grapes showed rapid berry growth at stage III after veraison compared with crackinginsensitive ‘Campbell Early’. Depending on the locations of berry divided into the stylar end, equator, and stem-end, cracking rates were also different with 59.0, 34.5, and 6.5% in ‘Kyoho’ and 74.5, 12.5, and 12.0% in ‘Fujiminori’. After the veraison stage, larger cracking of berry was observed from the fruit lenticels which were degenerated from stomata and stylar scar in ‘Fujiminori’ compared with cracking resistant ‘Campbell Early’ grape. 91 
P-16 A genetic analysis of berry quality traits in Spanish red wine grape S. Song 1, 3 , A. Mangado 1 , M. del Mar Hernández 1 , I. Provedo 2 , C. Menéndez 1 * 1 Departamento de Agricultura y Alimentación. Universidad de La Rioja. Instituto de Ciencias de la Vid y el Vino. UR-CSIC-GR., Logroño, Spain; 2 Viveros Provedo, Varea, Logroño, Spain; 3 College of Enology, Northwest Agriculture & Forestry University, China *Corresponding author: cristina.menendez@unirioja.es The quality of wine is mainly dependent on the quality of the grape berry. Yield, berry ripening, berry size, acidity and sugar content, and phenolic maturity; expressed as total polyphenol index (TPI), color intensity (CI), tannin content, anthocyanin content (both extractable and total); are major traits associated with berry quality and aging of wine, respectively. These traits result from complex developmental processes influenced by genetic and environmental factors.A segregating population was constructed with 151 genotypes derived from a cross between two representative Spanish red wine varieties: Tempranillo and Graciano. Tempranillo is the most widely planted indigenous variety, present in 28 Spanish wine regions and is associated with good quality wine. Graciano is a red Rioja variety used in blends with Tempranillo; Graciano has a later sprouting and maturation date, lower productivity, higher acidity, smaller berry size, and higher phenolic content compared to Tempranillo. We have evaluated the population for three consecutive years. Phenotypic correlations among traits within years; and between years within traits were determined. Significant correlations were found between yield, CI, skin anthocyanins, total and extractable anthocyanins content, TPI, tannin and sugar content, and seed traits within years. Simultaneously, parental genotypes and progeny were screened for 62 SSRs loci and 6 AFLP primer combinations in a LI-COR IRD 4200 Sequencer. A genetic linkage map is being constructed for each parent using Joinmap 4.0. This will allow the identification of QTL responsible for traits of oenological interest in these representative Spanish red wine varieties. 92
