“…In the reverse crossing combination (P. cerasifera × P. armeniaca), the number of fruitlets in relation to the number of pollinated flowers was very small -0.2%. Arbeola et al (2006) obtained much more fruitlets in the crossing of these species. Depending on the year and the genotypes being crossed, the percentage of fruit set in their trials ranged from 0.9% to 18.7%.…”

Szymajda M., Napiórkowska B., Korbin M., Żurawicz E. (2015): Studies on the interspecific crossing compatibility among three Prunus species and their hybrids. Hort. Sci. (Prague), 42: 70-82.In 2011-2013, a study on the crossing compatibility and the setting of fruit in distant hybridization within the genus Prunus, among the species P. armeniaca L. (apricot), P. salicina Lindl. (Japanese plum), P. cerasifera Ehrh. (myrobalan plum) and the hybrids P. salicina × P. cerasifera was conducted at the Institute of Horticulture in Skierniewice, Poland. The percentage of fruit set depended on the direction of pollination of the crossed species. Most fruits were obtained by crossing P. salicina × P. armeniaca and P. salicina × P. cerasifera. The largest number of fruitlets in relation to the number of pollinated flowers was obtained when two genotypes of P. salicina -Czernuszka and D 17-73, were the maternal parents. The results show that the crossing compatibility and effectiveness in the cross-breeding of the studied species of Prunus are influenced to a greater extent by the genotype of the maternal form of P. salicina than by the genotype of the paternal form of P. armeniaca and P. cerasifera.

“…Second, to obtain seeds with different embryo sizes, because the openpollinated fruits rarely contained small embryos, seeds were collected from F 1 fruits from interspecific crosses between P. cerasifera and P. armeniaca where seeds of different sizes are present because of embryo abortion. Embryo development in these crosses was arrested at an early stage as a result of incompatibility barriers (Arbeloa et al, 2006). The three 'Myrobalan' clones ('Myrobalan 1' to 'Myrobalan 3') were pollinated for these interspecific crosses.…”

In vitro embryo culturing has arisen as a powerful tool for embryo germination of low-viability seeds. This tool has been used to germinate seeds of early-maturing or hybrid Prunus species. ‘Myrobalan’ (Prunus cerasifera Ehrh.) is a widely used rootstock for plum and apricot cultivars and its interspecific hybrids have a clear potential for breeding purposes. However, early seed abortion is often a problem in interspecific crosses because no protocol has been established yet for ‘Myrobalan’ seeds. In this work, we developed a procedure for in vitro germination of embryos of different sizes. Various factors affecting embryo germination such as the culture media, the presence of cotyledons, the stratification temperature, and the embryo size were tested in three different ‘Myrobalan’ clones. The developed protocol includes the use of full embryos that were stratified at 4 °C and cultured in C2d culture medium. The germination rate was strongly affected by the embryo size and reached 90% germination with intermediate- to large-sized embryos (6.5 to 10 mm). However, smaller embryos could also be germinated, and up to 30% germination was achieved with 0.5- to 2-mm long embryos. The results obtained here provide a protocol for in vitro germination of ‘Myrobalan’ embryos that will likely be helpful in breeding programs.

“…Interspecifi c hybridizations between myrobalan plum ( P. cerasifera ) and apricot ( P. armeniaca ) have been undertaken in France and Spain to create hybrids that combine graft compatibility with apricot, favorable rootstock traits from myrobalan plum (adaptation to heavy soils, rooting ability) and resistance to pests and diseases from both species. The fi rst results obtained show that the creation and selection of these interspecifi c hybrids seems to be a very promising way to improve apricot rootstocks (Poëssel et al 2006 ;Arbeloa et al 2003Arbeloa et al , 2006 .…”

“…In controlled crosses, when using a self-compatible female parent, all or part of the seedlings may not come from the cross but they may come from selfi ng . Likewise, the incidence of accidental pollination with undesired pollen on interspecifi c hybridizations was studied by Arbeloa et al ( 2006 ) . The percentage of desired hybrids was lower than expected.…”

Apricot is in the Rosaceae family within the genus Prunus L., subgenus Prunophora Focke, and the section Armeniaca (Lam.) Koch. Depending on the classifi cation system, the number of apricot species ranges from 3 to 12. Six distinct species are usually recognized: P . brigantina Vill., P . holosericeae Batal, P . armeniaca L., P . mandshurica (Maxim), P . sibirica L., Japanese apricot P . mume (Sieb.) Sieb. & Succ. Vavilov placed apricot in three centers of origin: the Chinese center (Central and Western China), the Central Asiatic center (Afghanistan, northwest India and Pakistan, Kashmir, Tajikistan, Uzbekistan, Xinjing province in China and western Tien-Shan), and the Near-Eastern center (interior of Asia Minor). Kostina further divided the cultivated apricot according to their adaptability into four major ecogeographical groups : (1) the Central Asian group, (2) the Iran-Caucasian group, (3) the European group, and (4) the Dzhungar-Zailij group. Many local cultivars are grown in the different areas and producing countries; however, these cultivars lack important traits that needed by modern production and marketing systems. Breeding programs have and continue to develop cultivars with improved adaptability to the environment (temperature requirements, water defi cit), extension of the harvest season, fruit quality for fresh consumption and processing, productivity, adequate tree size, and resistance to biotic stresses.
