Background Eucalyptus globulus is a widely planted species in temperate regions of the world for pulpwood production. Its good characteristics for kraft pulping in addition to a broad adaptability to different site conditions have led this species to be employed in commercial plantations and to be included in breeding programs [1]. Uruguay has approximately 300.000 hectares forested with E. glo...

Traditional tree improvement programs start with deliberate phenotypic selection of candidate trees followed by rounds of recurrent selection characterized by cumulative incremental gain advancements. While effective, the process is elaborate, quantitatively oriented, and follows sophisticated breeding theories. Breeding and testing start with the selection of pre-determined mating designs, req...

extended abstractbackground and objectives: loquats have formed different ecological types during their cultivation and adaptation in different parts of the world. the first step in the breeding operation is the identifying of the spread center accompanied the studying of the variation between genotypes. in this research, 20 loquat genotypes were evaluated using fruit morphological markers to i...

Alternative ways to control caterpillar pests and reduce the use of pesticides in apple orchards are in the interest of the environment, farmers and the public. Great tits have already been shown to reduce damage under high caterpillar density when breeding in nest boxes in an experimental apple orchard. We tested whether this reduction also occurs under practical conditions of Integrated Pest ...

Background Somatic embryogenesis (SE) is the only clonal propagation method that has potential for large scale production of elite conifer plants from the breeding programs. Methods that support bioreactor-based methods for SE propagation are developed [1,2]. Samples of somatic embryos can be stored indefinitely under liquid nitrogen for future plant production. Somatic embryo cultures are also...

Self-incompatibility is one of the most important difficulties in almond production which reduce fruit set dramatically and makes orchard management difficult. Therefore, breeding almond to produce self-compatible genotypes is very important. In this research identification and screening of 86 almond progenies obtained from selfing Touno after the self-pollination by PCR reaction with specific ...
