|
Starting date: |
1988 |
|
Duration: |
15 years |
Project objectives:
To reduce the time and cost of breeding new almond cultivars, by developing techniques (molecular markers) that improve the efficiency of selection.
To construct a basic map for almond of approximately 250 markers.
To elaborate a reduced map (a map with 30-50 markers covering the entire genome at regular genetic distance intervals) for some populations using markers which show useful variation in its parents.
Project summary:
Almond is an important nut crop in Spain. Conventional breeding for almond cultivars is slow. The participants in this project are developing molecular markers (isozymes, RFLPs and RAPs) for almond, with the main aim to facilitate and early preselection of young seedlings. The analysis of some progenies will allow to detect cosegregations (genetic linkages) between the markers and the agronomic characters. Thus identify valuable early selection criteria which will increase the efficiency of the breeding programme.

Project objectives:
The objective is to obtain varieties with outstanding agronomic and commercial features: late blooming, self-fertility, high productivity, strong vigour, limited branching, upright tree growth habit, fruit of quality (with hard or semi-soft shell, absence of double kernel and good kernel appearance), etc.
Project summary:
The development of the project has had two distinct phases. In the first phase, carried out during the period 1975-85, a large number of crosses, with a relatively reduced number of seedlings per progeny, were made. The objective was to get outstanding cultivars and also information about the heredability of important traits. During this phase, some native cultivars, producing nut of quality, were extensively crossed with late blooming foreign cultivars. In the second phase, started in 1990, a larger number of seedlings per progeny are being produced. In many progenies, early selection of very young seedlings is carried out in the nursery using different criteria. Some crosses are used to try to find linkages between molecular markers and important tree and nut traits.

Project objectives:
To select almond × peach hybrids, obtained at IRTA Mas Bové, to be useful as rootstocks for almond and peach.
To study the interest of almond cultivars, to be used as producers of seedling rootstocks, for almond growing in dry land.
Project summary:
In the period 1979-81, 60 hybrids were obtained at Mas Bové by raising various almond × peach crosses. This trees have been tested for their ability as almond or peach rootstocks. Aptitude to propagation, vigour and tolerance to dry conditions are outstanding features in the process of selection. Three hybrids have been preselected and will be included in trials to assess their interest.
In addition, several trial have been made, in orchard and in nursery, to evaluate the behaviour, as rootstock for almond, of seedlings derived from various almond cultivars. This research line was closed at IRTA Mas Bové in early 1995.

Project objectives:
The aim of this project is the release of new cultivars improving the present ones mainly by their agronomical and commercial quality and their productivity. These objectives can be attained by the introduction of the tzo main traits of self-compatibility and late blooming. Other objectives include a constant and high production, easy management (compensated branching to reduce pruning and easy mechanical harvesting). Pest and disease resistance will be evaluated, as also the adaptability to irrigated and non-irrigated conditions. The plants obtained during the development of previous projects will be finally evaluated and selected. Eventually new crosses will be planned. At the same time genetic studies on the transmission of several traits, mainly self-compatibility, will be carried out.
Project summary:
Two points have been lately stressed: the study of self setting in several advanced selection and the presence of double kernels. The first trait is related to autogamy and to flower morphology. The second traits seems to depend on the opening time of the flowers producing fruits.

Project objectives:
The aim of this Project is to work in two parallel ways:
a) Obtention and selection of rootstocks belonging to the "pollizos" (P. insititia) population, compatibles with almond, as possible stocks for intensive, irrigated, orchards.b) Inter specific Prunus hybrids in order to obtain and select rootstocks for dry land and irrigated areas with better performance than the used at present.
- Showing higher propagation rate by hardwood cuttings.- With less feather emission in the cutting production hedge.
- Erect behaviour of the plants in the nursery row.
- With differential characteristics to avoid errors to the nurseryman
- Resistant to adverse conditions as: asphyxia, soil pathogens (animals or cryptogamous): nematodes, Agrobacterium, etc.
Project summary:
The work of this project started some twenty years ago with a collection of "pollizo" seedlings. The first step was the selection of those showing a good ability to root by hardwood cuttings. The better ones were put in nurseries to test the compatibility with peach, almond, apricot and plums. The result is the selection of two clones, "Montizo" and "Monpol". Trials in progress are being done to study the behaviour of these promising rootstocks.
A breeding program by Prunus hybridisation ten started ten years ago with some trials aiming to individualise almond varieties capable to root by hardwood cuttings. "Garfi" was selected as the almond parent to cross with peaches or other Prunus. Crosses with "Nemared" peach gave a hybrid red leafed offspring. Successive trials for propagation capability, chlorosis and nematode resistance, etc., are in progress.
New crosses are been done more recently and some others are foreseen aiming to obtain complex hybrids with the idea to assemble interesting traits that are present in different Prunus species.

Project objectives:
The aim of this proposed research project is to study the behaviour of several Prunus rootstocks against root-knot (Meloidogyne spp.) and lesion forming nematodes (Pratylenchus spp.).
Nematode populations will be characterised and maintained throughout the study. Plant material supplied by SIA will be subjected to screening tests under greenhouse conditions. Rootstocks of agronomic interest, both susceptible and resistant, will be evaluated in micro plot in field conditions. Resistant genotypes will be verified with multiple inoculations (several species and populations) to check the range of resistance to Meloidogyne spp.
Wild Prunus species will be screened in the search for possible source of resistance against Pratylenchus vulnus. Rootstock evaluations will be complemented with histological studies with the purpose of having a better knowledge of the mechanisms of resistance involved. The expected benefits will allow to control these pests in rootstocks that are currently in the process of selection in the most economic and effective way avoiding the use of nematicides and thus the risk of affecting the environment.

Project objectives:
The aim this project is the release of new cultivars improving the present ones mainly by their agronomical and commercial quality and their productivity. These objectives can be attained by the introduction of the two main trais of self-compatibility and late blooming.
Project summary:
The several spanish almond cultivars have early or medium blooming time if we compare them with cultivars growing in other world countries.
At the same time, with the exception of "Aylés", "Guara" and "Moncayo" cultivars (resulting from breeding programs in S.I.A. - Zaragosse) does not exist others spanish self-compatible cultivars.
A later blooming would coincide with a higher favourable climatology and would avoid these unfavourable conditions. Likewise, introducing self-compatibility it will be avoided the need of pollonizers in the orchard.
Breeding programs conducted to obtain late flowering end or self-compatibility cultivars has been fulfilled.
At present we are proceeding to the selection of the progenies obtained and we intend in the light of new knowledge, to accomplish new crosses in order to release new cultivars with a higher self-compatibility and late flowering time than those obtained until now. In the selection process we also will consider as interesting characteristics drought and pest resistances.

Project objectives:
The several spanish almond cultivars have early or medium blooming time if we compare them with cultivars growing in other world countries. Breeding programs conducted to obtain late flowering and or self-compatibility cultivars has been fulfilled.
Project summary:
The aim of this project is the release of new cultivars improving the present ones mainly by their agronomical and commercial quality and their productivity. These objectives can be attained by the introduction of the two main traits of self-compatibility and late blooming. Other objectives include a constant and high production, easy management (compensated branching to reduce pruning and easy mechanical harvesting). Pest and disease resistance will be evaluated, as also the adaptability to irrigated and non-irrigated conditions. The plants obtained during the development of previous projects will be finally evaluated and selected. Eventually new crosses will be planned. At the same time genetic studies on the transmission of several traits, mainly self-compatibility, will be carried out.
