Walnuts are considered recalcitrant to tissue culture, with a great genetic determinism on all stages of micropropagation; while other factors, also impact, become more complicated the reproduction newly realized varieties. In this research, holistic approach aimed determine influence genotype and nutritive formulation throughout whole cycle micropropagation four Persian walnut varieties (Juglans regia L.) was presented. During in vitro establishment it determined that besides culture...

The intensive production of timber from walnuts is mainly hampered by the scarcity varieties for this purpose. While hybrid progeny Mj209xRa considered suitable in Europe, problems associated with its recalcitrance, low ability rooting and high mortality acclimated vitroplants, limit reproduction elite trees. This research was aimed to assess influence two methods vitro introduction several walnut genotypes, determine effects temporary immersion systems (TIS) on proliferation rooting, reduce...

Aimed to obtain purple garlic varieties, 360 bolting bulbs from the Protected Geographical Indication (PGI) “Las Pedroñeras” were selected for their size, and presence of abundant external scales. After a further selection, 243 out discarded due undesired characteristics, as light color, high number small cloves, cloves affected by Fusarium spp. mites, among other. It was stablished that each bulb would give rise family. Thus, 117 families planted under random design during season 2021-2022....

Despite garlic (Allium sativum L.) being recognized as the second most important species in Allium genus, a limited number of varieties are available worldwide. Aiming to develop new purple varieties, representative sample was used determine extent phenotypic variability for commercially desirable characteristics. Initially, 360 bolting bulbs were selected based on their size and abundant external scales. After further assessment, 243 discarded due undesirable traits such light color,...

Walnut is one of the most common nuts in many countries world. It used cooking and traditional medicine. cultivation on an industrial scale Kazakhstan began only 2016-2017, so scientists this field do not yet have any scientific experience. The article presents results studies influence nutrient medium compositions Murashige-Skoog Driver-Kunzhuki microclonal propagation different genotypes walnut Juglans regia L. Two varieties were selected as mother plants: Uzbek variety Ideal Chinese...

INTRODUCCIÓNLa agricultura moderna al poner énfasis en el logro de mayores producciones, ha originado la sustitución las variedades locales por monocultivos que su mayor productividad son ampliamente utilizados.Esto supuesto una drástica disminución variabilidad genética (erosión genética) presente los agrosistemas que, además afectar a estabilidad, conllevado pérdida recursos genéticos esenciales para obtención nuevas variedades.El acelerado deterioro biodiversidad provocado últimos años...

Aim of the study: The research was aimed to design microsatellite markers for genotyping and differentiation trees from walnut hybrid progeny Mj209×Ra. As a secondary objective, transferability classificatory capacity some these loci were assessed Juglans genus.Area most widely spread used in Europe wood production used. Pure species genus as Arizona black (J. major (Torrey) Heller) European or common regia L.), well different Mj209xRa lots, also included.Materials methods: Genomic DNA tree...

The success of walnut ( Juglans sp.) planted forests for timber production have been very variable and genetic material is considered as one the main drivers (together with site selection forest management) or failure plantations, performance trees from seed variable. Considering relevance this material, several clones selected research conducted in order to improve micropropagation procedures. objective present study analyze effects different rooting acclimation rates in-vitro hybrid x...

Prunus genus include fruit and wooden species. Because its economic importance, both phenotypic genetic markers have been developed used in studies. Among them, for their versatility, degree of transferability repeatability, some microsatellite sets several species from this genus.Although they successfully inside the Rosaceae family, to other and/or provenances different what were designed, must be first assessed. Thus, higher number assessed, applicability performing Hence, functionality...

Desde finales del siglo XX se han desarrollado en España diferentes modelos de plantaciones enfocadas a la producción maderas nobles (nogal–Juglans sp.– y cerezo–Prunus sp.–). El éxito estas ha sido dispar, considerándose factores como el material genético selección sitio claves para éxito/fracaso inversiones. Este trabajo presenta resultados crecimiento forestales nogal clonal (NAT-7-BN) condiciones edafoclimáticas varias localidades España. NAT-7-BN alcanza Galicia (13 años) un DAP 19,7...
