1. Introduction

Stone fruit is a generic term used to define fruits which includes peach, nectarine, plum, apricot, almond and cherry which are generally grown in temperate climatic conditions. The main feature of stone fruit is having fleshy layer, mesocarp, as edible pulp surrounding a relatively large, hard pit commonly known as ‘stone’ that shields and protects a seed. The commercial production of stone fruits is confined between the latitude of 30 and 40°N and S, although it is now grown almost all over the world. The major stone fruit-producing country is China accounting about 50 per cent share of the total world production. In India, stone fruits are grown on a commercial scale in mid-hill Himalayan states, viz. Himachal Pradesh, Jammu and Kashmir, Uttarakhand, as well as in a limited scale in north-eastern states. These fruits are generally grown on soils having bulk density, parasitic nematodes, root rot problems, fungal pathogens or other soil and replant problems.

There are over 400 to 430 species in the genus Prunus, (includes edible as well as ornamentals fruit crops) but only 89 are listed in the Genetic Resource Information System [1, 2]. In India, about 36 Prunusspecies have been reported so far and 18 species are useful for cultivation for different purposes [2, 3, 4] (Figure 1).

2. Almond

Almond is classified in the subgenus Amygdaluswithin the genus Prunus, distinguished from the other subgenera (Prunophoraand Cerasussections) by the corrugated seed shell [5]. Twenty two almond species were classified into five taxonomic sections including: Euamygdalus, Spartioides, Lycioides, Chameamygdalusand Leptopus[6]. Being a temperate crop, almost all the varieties of almond can be grown successfully in the temperate regions of India. However, most promising cultivars which have been tried or being cultivated in various parts of the world are described here under.

2.1 Blanquerna

It is derived from self-pollinating ‘Genco’, self-compatible almond cultivars developed at Zaragoza, Spain [7]. The cultivar do not requires any foreign intervention for their proper pollination and consequently for the production of a commercial crop. In addition, kernels from these new cultivars show no doubles.

This cross was made with the aim of utilizing a self-compatibility source other than ‘Tuono’, so far the mostly utilized parent in almond crosses [8].

3. Apricot

According to different apricot classifications, reported by Lingdi and Bartholomew [9], there are 11 accepted apricot species within the section Armeniacaincluding P. brigantinaVill.

(black apricot, a natural plum-apricot hybrid), P. holosericeaBatal. (Tibetan apricot), P. hongpingensisLi., P. zhengheensisZhang & Lu., and P. hypotrichodesCardot. Also, the desert apricot (P. fremontiiS. Wats.), originated from southern California deserts, is worth mentioning among the listed species, can be freely hybridized with them, and has close morphological traits to other species of apricot [10]. All the Apricot varieties in the Mediterranean region and USA are of European group and have very little genetic diversity [11]. The European group of Apricots is the youngest in origin and Dzhugar Zailij (Soviet Central Asia such as Kazakhstan) is the oldest. The varieties belonging to European group are self-compatible. Majority of the varieties of Central Asian, North African, Near East and Caucasian origin are self-incompatible [12]. Around one hundred thirty one cultivars and thirteen rootstocks have been reported in USA [13]. The description of major apricot varieties is described here.

4. Cherries

There are over 30 species of cherries, most of which are endemic to Europe and Asia. In the subgenus Cerasus, P. avium, P. cerasus, P. fruticosa, and also P. tomentosaand P. pseudocerasusin China and domesticates of P. serotinain South America are grown for their fruits [21, 22].

Sweet cherries can be divided into subgroups, based on fruit color, shape, and texture [22]. The subgroups include Geans which are heart shaped with tender flesh, black Geans which have dark-colored flesh, amber Geans which have light yellow fruit with translucid flesh and skin, Bigarreaux which has firm and cracking flesh, and Hearts which are dark in color with flesh texture between Geans and Bigarreaux.

Sour cherries have also been further categorized, based on skin and juice color and fruit shape, into either Amarelles (pale red fruits with more or less fattened shape and colorless juice) or Morellos (dark red fruits with globular or cordiform shape and red to dark red in juice color) [23]. Duke cherries (with dark red skin and semiacid juice) are considered to be a hybrid between sweet and sour cherry and now classifed as P. x gondouiniiRehd. [24].

Although there are numerous other cherry species in the Cerasusand Padussub-genera, few of these species have been used to genetically improve sweet and sour cherry scion cultivars. Most of the species and interspecific hybrids developed are used for rootstock improvement. Prunus aviumis primarily an European species, which ocuurs abundantly in wild form on the forest slopes of Southern, Central and Western Europe. Pomologically, according to fruit firmness, cherry cultivars are divided into the Heart cherry group, with mainly early ripening cultivars that have a soft flesh and the Bigarreau group. Among them few have been described here under.

4.1 Bada

Resistant to fruit doubling. The fruit ripens earlier than Napoleon. Blooms relatively late but overlaps with ‘Bing’ and ‘Napoleon’, serves as good pollen source for these varieties.

4.2 Balaton

Originated in Hungary, as a local variety. Compared to ‘Montmorency’ the fruit is larger, firmer, sweeter and redder and it has a juicy flesh. The pits are slightly larger than other varieties and may cause problems for processors.

4.3 Bing

It is originated in United States from an open-pollinated population of Black Republican which is the most traditional and representative cherry of America. Fruits are firm, sweet, medium to large in size, attractive black color with excellent flavor. Its dark red flesh is firm, not very fibrous, juicy, sweet and very good in quality. Bing produces an excellent canned product but is inferior for brining unless picked before fully ripe. However, its susceptibility to canker, severe fruit splitting, and sensitivity to our cold climate does not make it an ideal variety.

4.4 Blackgold

A late mid-season, self-fertile, sweet cherry selection and primary use is for fresh eating. This is the latest blooming sweet cherry and has remarkable tolerance to spring frost.

4.5 Black Republican

According to geographical distribution, the peach cultivars have been divided into three groups namely, Northern, Southern and European or Persian group. Peach cultivars can also be divided into two groups high chilling and low chilling on the basis of their chilling requirements. Low chilling cultivars developed in Florida during last three to four decades have become very popular in the sub-mountainous Himalayan region.

The fruit ripens about a week before Garnet Beauty. It is winter hardy, disease resistant and has few split-pits. The fruit have an attractive red blush over a bright yellow background; the deep yellow, low oxidizing flesh is of good quality and is nearly freestone when fully matured [35]. Because the fruit is small tomedium sized, this cultivar must be thinned early and adequately to obtain suitable size.

5.1.27 J H Hale

Around 1900, a peach grower J.H. Hale found an off type plant in his farm which performed well at Georgia due to its superior firmness. After that this variety is widely planted in USA and was often used in breeding programmes. It is thought to be a chance seedling of Elberta. The cultivar is self-unfruitful.

6. Plums

Most plum cultivars belong to only two species: the hexaploid European plum (P. domestica) (2n = 6x = 48) and the diploid Japanese plum (P. salicina) (2n = 2x = 16). P. domestica, which categorized in European plums, is grown not only in Europe but also in other continents as the most common plum. Based on the fruit characteristics, this species can be divided into several groups including plums, prunes, gage plums, and mirabelles, as well as the wild plums like cherry plums, bullaces, damsons, and sloes [36].

P. salicina,Japanese plums tend to be oval or heart-shaped and come in yellow, black, or red varieties. These types of plums have firm flesh and are often eaten fresh. Types of European plums are usually very sweet with juicier flesh and are used in baking or for making jams and jellies. There are many varieties of plums ranging in taste from sweet to tart. Some types of plums have a red sour flavored-skin that surrounds sweet juicy yellow flesh. Other varieties of plums are extremely sweet with dark purple skin and amber-colored flesh.

7. Conclusion

Stone fruits or Prunusspp. are deciduous tree species originating from the temperate zone of the northern hemisphere. Plum, peach and nectarine, sweet and sour (tart) cherry, apricot and almond belongs to the group of stone fruits according to pomological classification. The genus Prunushas a vast species and varietal biodiversity expanded world over as wild, semi-wild and cultivated forms. Considering the significance in terms of its share to the plant biodiversity, genetic resources and horticultural utilization, it becomes very essential to create repositories, to generate data base and to adopt collaborative conservation strategies to mitigate the threats to this genus. Stone fruits typically have long breeding cycles; thus, developing a new cultivar through traditional breeding may require many breeding cycles and dozens of years. Major efforts in stone fruit breeding has been done in early twentieth century, however major progress was achieved in the second half of the twentieth century, with uneven results which differ from less effectual (in apricot) to extraordinarily successful (in peach and nectarine).
