An efficient protocol for seed germination is needed when developing a peach breeding programme in order to ensure the development of new hybrids. The stage of stratification is crucial as seeds have to be kept in low temperature for a long period of time, sometimes leading to the loss of their viability. The cultivars used in the study were 'Andross', 'Baby Gold 6' and 'Catherina'. Different methods of stratification were applied: a) petri dish with filter paper with 10, 20 and 30 seeds, b) seeds with and without integument in bags with perlite and c) in vitro seed. The seeds were kept at 2±1°C for 2 months, after which they were planted in a substrate composed of peat and perlite and placed in a germination chamber at 20±2°C, and 80% RH. The parameters studied were: the fresh seedling weight, root length, germination, rosetted plants and plant survival when being moved to greenhouse conditions. The best results for germination and survival were obtained when using stratification in a Petri dish with filter paper, independent of the number of seeds used. © ISHS 2012. Source

Region of Murcia is one of the major peach-producing areas in Spain and it is also one of the oldest within the European Union. Payments over property rights of new peach cultivars have proved to be very controversial. When a producer designs a new plant, he or she must pay royalties for the new cultivars to the market, use free cultivars or develop new cultivars. The latter option is currently being used by NOVAMED S.L. The company consists of several major fruit-operators located in the Region. In collaboration with the Murcia Institute of Research and Agricultural Development (IMIDA) and in order to avoid breeder's dependence and costly royalty payments, the company has signed an agreement to obtain cultivars adapted to the Region's conditions. The company is actually working on a peach and nectarine program. The program's general objectives seek to develop cultivars that have been adapted to the soil and climatic conditions of the region achieving early maturing, high productivity and excellent organoleptic qualities. © ISHS 2012.
