Materials and methods
This research was held in MVRI Turkey during the 2008 vegetation periods in Manisa province. Manisa is
located at 71 m above sea level, and 38˚36” East and 27˚24” North hemisphere. According to the climatic
records of state meteorology station, in vegetation period the day number with the average temperature
above 10 ⁰C was 271, from 27th February to 23rd November 2008. Mean temperature was 21.5 ⁰C, and the
sum of effective temperature was 2880.3 ⁰C. Annual precipitation was 480 mm, and relative humidity was
60.5.
SC was used by two different cultivation techniques as raisin (SC r) and table grape SC tg) production
purpose which was used for understanding the differences of selected clones as S, S4, S5 and S6.
Samples were collected during ripening period by a week intervals and at local harvest tame for determine
the varietal and cultivation differences. Samples were collected during ripening period from 08,07,2008 to
06,08,2008 for each analyze.
In the field, yield (kg vine-1) was determined by weighting all the clusters on 10 vines and mean cluster
weight were determined by using 10 clusters for each clone. Cluster numbers (n) was determined by
observing all clusters on 10 vines for each grape genotype.
In the laboratory, berry weight (g bery-1) was determined by 100 berries collected from 10 clusters. Berry
shape index (l/w) was calculated by 100 berries collected from 10 clusters. Soluble solids of must (⁰Brix)
analyzed by hand refractometer (Atago 9313), PH was determined by pH meter. Titration acidity (tartaric
acid) was analyzed by titration method (Anonymous 1997). P-value was tested in sample juices by the Bio-
Electronical Terrain-Analysis (BE-T-A) from MED Tronic MT 732-Full-Microprocessor-Controlled System
(Heinrich and Rey, 1997).Berry color was determined by cromometer (Konica Minolta CR400 with the
Hunter scale, L, a, b; McGuire 1992).
The researches were designed as 3 replicated randomized parcels. Data were analyzed using SPSS for
Windows 12.1, and graphs were performed by Windows Excel.
Results and Discussion
Yield
Yield values (kg vine-1) of SC clones were recorded 22.39, 19.11, 16.43, 11.92, 11.05 and 7.62 kg vine-1 that
from SC r, SC tr, S5, S1, S6 and S4 respectively (Tab. 1). The highest yield value was obtained from SC r as
22.39 kg/vine -1 and least yield was observed from S4 clone as 7.62 kg/vines-1. The difference between S4
and SC r was about 3 fold. There was also two fold difference between S4 and S5 clones.
Cluster numbers
Cluster numbers were determined as 62.33, 32.3, 29, 27, 27 and 25 from SC r, SC tg, S1, S5, S6 and S4
respectively (Tab. 1). The maximum cluster number SC r was almost 2 fold the other clones. There were
close values of cluster numbers among the clones S1, S4, S5 and S6.
Berry weights
Single berry weights were observed between 1.68 g from SC r which was for raisin production purpose and
3.04 g from SC tg which was for table grape (Tab. 1). Because of the much more gibberellins application for
table grape production the biggest berries was obtained. There was only one gibberellins application as 20
ppm at the end of fruit set in Turkish raisin industry.
Cluster weights
Cluster weights of the clones were 604.37 g, 602 g, 454.6 g, 389.8 g, 375.3 g and 357.23 g from SC tg, S5, S6,
S1, S4 and SC r respectively (Tab. 1). Because of gibberellins application SC tg cultivated for table grape
purpose cluster weights were the maximum but S5 was differed among the other clones that is also attributed
to its genetic difference.
