“…The increasing number of self-incompatible cultivars in the last years can be explained by using Asian or North American self-incompatible cultivars in breeding programmes that aim to create new genotypes with the traits such as: Plum pox virus resistance (Badenes, Llácer 2006;Karayiannis 2006;Krška et al 2011), frost tolerance (Benediková 2006;Krška et al 2006), increase of the sugar content (Ledbetter et al 2006), or extending the harvest time (Pedryc, Kerek 1999;Topor et al 2010). Some of the self-incompatible cultivars are frequently used in apricot breeding programmes.…”

Testing of self-(in)compatibility in apricot cultivars from European breeding programmes

2013

Self-(in)compatibility was tested in 40 new apricot cultivars from European breeding programmes. Pollen-tube growth in pistils from laboratory pollinations was analysed using the fluorescence microscopy. Cultivars were considered self-compatible if at least one pollen tube reached the ovary in the majority of pistils. Cultivars were considered selfincompatible if the growth of pollen tubes in the style stopped along with formation of characteristic swellings. Of the examined cultivars, 18 were self-compatible and 22 were self-incompatible. Fluorescence microscopy provides a relatively rapid and reliable method to determine self-incompatibility in apricot cultivars.

“…It flowers later, two days after the Velkopavlovická variety (Krška 1996), is self-fertile with regular high yield, and ripens seven days after Velkopavlovická. Its fruit is of high quality with red-violet cheek, fruit mass being 55 g. It is suitable mainly for direct consumption and has a low susceptibility to pests (Krška et al 2006).…”

“…It flowers one day before the Velkopavlovická variety and ripens three days after Velkopavlovická. Fruit size is 65 g. It is very attractive with a very tasty flavour and medium yield, and it is especially suitable for direct consumption (Krška et al 2006). Mean values of parent varieties are shown in table 1.…”

ABSTRACT:In the years 2005, 2006, and 2007 the described pomological characteristics were evaluated and both heritability and correlation coefficients of the determined characteristics of parents and progeny were estimated for the Minaret × Betinka apricot hybrid population. Estimated heritability of fruit weight, over colour and flesh consistency was approximately 0.9. Heritability of flesh colour, fruit attractiveness and fruit flavour ranged from 0.6 to 0.9. The correlations show a strong dependence of the following characteristics of parent varieties and progeny: over colour and fruit attractiveness. Medium strong dependence was determined in the following characteristics: fruit colour and fruit flavour. Weak dependence was found in the case of fruit size.

“…When crossing the parents of resistant to susceptible, using Harlayne species, a hypothesis was reached on heredity of three dominant genes which are responsible for PPV resistance [42]. In the progeny derived from the four apricot crosses (resistant to susceptible), the segregation ratios were compatible with the hypothesis of three dominant genes being responsible for PPV resistance, with "Harlayne" being heterozygous for all three genes [43].…”

This chapter outlines the evolution of apricot which took place not only in its original gene centers but also after its domestication in new, secondary areas. During this process, Ice Age, migration of nations as well as the influence of mountains played a significant role in the diversity of this fruit species where many clones of genetically similar cultivars and ecological groups of apricots were formed. The chapter presents the list of donors of main biological and economic properties which are important in breeding to increase the adaptability of the species. The chapter summarizes some of the breeding results and inheritance of characters related to frost hardiness of blossom buds, fruits and plum pox virus (PPV).
