THE FRUIT QUALITY CHARACTERISTICS TO SOME VALUABLE BLACK CURRANS SELECTIONS
Abstract
In Romania, the breeding program for currant begun 60 years ago. Till now from autochthon black currant breeding program were obtained six black currant cultivars. The most cultivated Romanian black currant cultivars are Abanos and Deea. But the requirements of the growers and consumers are in continues change. Therefore it is very important the study of local varieties, domestic and foreign ones, to find sources for new varieties resistant to diseases and pathogens also with good quality of fruit, economically valuable. In the present paper we are presenting seven quality indicators to six black currant genotypes to identify new valuable resources for our actual breeding program. The study was conducted at RIFG Pitesti, Romania, during 2011-2034, in a subdivided plot design with factorial arrangement 6x3, after the following experimental scheme: A Factor - genotypes, with six graduations: a1=10-10-40, a2=10-10-38, a3=10-10-10, a4=10-10-42, a5=10-2-16, a6=10-2-3. B Factor-the study year, with 3 graduations b1=2011, b2=2012, b3=2013. For quantifying the fruit quality characteristics, some biometric fruit quality indicators were made. Over the studied period the genotype 10-2-16 recorded the highest size index value (27.53 mm) and the genotype 10-2-3 recorded the lowest value (23.56) to the same indicator. The higher fruits firmness (0.90 N) and average weight of fruits (0.86g) were recorded also to genotype 10-2-16. The data were statistically calculated by ANOVA-method, using Duncan Test. (p=0.05).
