| Abstract:
The breeding work on European plum cultivars (Prunus domestica L. and Prunus insititia L.) is an objective necessity for many countries from Europe, Asia and North America. In this period of beginning of the Millennium, the conventional breeding methods for plum cultivars are still largely used in the majority of programs. The conventional methods have major limitations, which can diminish the perspectives of plum cultivar breeding with consequences on the future of this fruit crop. The plum breeding programs carried out in Romania during the last 40 years emphasized some aspects regarding the use of conventional methods: these methods are still the basis of creating the genetic variability and emphasizing of valuable genotypes; continuous modernizing of these methods can create new opportunities and chances of improving the variability; require a large volume of work, extended spaces, long selection period, high costs, etc.; the modern methods can be complementary to any of the conventional ones (selection, hybridization, ploidy, mutagenesis, etc.). The conventional breeding methods for plum cultivars are oriented on improving the fruit quality, improving the resistance to diseases, enlarging the adaptability to specific ecological conditions, improving productivity, etc. | |
