“…No Centro de Investigação e Desenvolvimento Agroalimentício da Múrcia, ao contrário, foi recentemente licenciado o Mayor, híbrido de amoreira x pessegueiro de elevado vigor, indicado para terrenos pobres, calcários e áridos (Rodriguez Navarro, 2002;Rodriguez Navarro e Carillo Navarro, 2002), mas muito suscetível aos nematóides gálicos (Pinochet et al, 2002).…”

O emprego de porta-enxertos sempre responde a modernas exigências pedidas por uma fruticultura tecnicamente evoluída, iniciou-se na Itália e, em geral, na Europa, a partir dos anos 60, mas assumiu importância com o desenvolvimento da fruticultura industrial. Para algumas espécies, dentre as quais particularmente a macieira e a pereira, este processo iniciou-se antes e evidenciou-se com maior rapidez, tanto que, atualmente, vêm-se se usando exclusivamente porta-enxertos clonais. Para outras espécies, como o pessegueiro, o pedido de novos porta-enxertos é mais recente em conseqüência da difusão desta espécie ainda em zonas não de todo evocadas de um ponto de vista pedoclimático, o qual, a exemplo daquelas caracterizadas por terrenos úmidos, maciços/compactos, subcalcários, alcalinos ou afetados pelo cansaço (Loreti, 1988). A vasta gama de porta-enxertos, atualmente disponíveis no mercado de viveiristas internacionais, tornou indispensável o conhecimento das características bioagronômicas dos mesmos, de modo a auxiliar técnicos e fruticultores na tarefa de efetuar uma apropriada escolha deles. Portanto, mantém-se oportuno reportar a descrição dos porta-enxertos mais conhecidos ou, pelo menos, daqueles que, através da recente experimentação, forneceram os resultados mais interessantes, e o que abordaremos nesse artigo.

Aim: The aim of present study was to evaluate the flowering and fruiting behaviour of different variety of peach, plum along with growth characteristics of their F1 hybrids and identification hybrid rootstocks for future genetic improvement. Study Design: The experiment was designed in Randomized Block Design Factorial with three replications. Place and Duration of Study: Rootstock hybridization programme were carried out at main fruit research station Punjab Agricultural University, Ludhiana, Punjab during 2016-17 and 2017-18. Methodology: Rootstock hybridization programme were carried out with three varieties two peach namely Sharbati and Flordaguard and one plum Kala amritsari and study the phenological, fruiting behavior and growth performance of seedlings of parents and F1 hybrids. Results: Higher days from full bloom to maturity take by Sharbati × Flordaguard (129.4 Days) and minimum in Kala amritsari × Flordaguard (111.1 Days). For completion of stratification seeds of Sharbati and Sharbati × Flordaguard took maximum days for stratification (90-105 Days and 30-105 Days, respectively) and minimum in Flordaguard (30-60 Days). Seed germination % higher in Flordaguard (97.15%) and minimum in Sharbati × Kala amritsari (70.81%). Pollen viability in stored and fresh pollen was highest in Flordaguard (96.26 and 97.58%), while, minimum in Sharbati (90.89% and 96.60%). Leaf colour values (L, a, b, chroma and hue) maximum were in Sharbati and minimum in Flordaguard and leaf colour values of both hybrids, were as Flordaguard. Maximum chlorophyll (SPAD units) were recorded in Flordaguard × Sharbati (42.87) which was at par with the SAPD values of Sharbati × Flordaguard. Leaves of Flordaguard and both the hybrids showed dark reddish green colour on upper and light reddish green in lower side of leaves. Seedlings of Sharbati, Sharbati × Flordaguard and Flordaguard × Sharbati showed better growth characteristics as compares to seedlings of Flordaguard. Conclusion: The advance candidate hybrid rootstocks may be useful for further exploitation for genetic improvement and development of rootstock with good nursery characters.

“…These showed that clones of P. cerasifera (Pierronnet & Salesses 1996) and the peach rootstocks GF677 and Peach Seedling (Zoina & Raio 1999) were susceptible to A. tumefaciens. The rootstock St. Julien 655/2, a hybrid of P. insititia × P. domestica, was moderately resistant to A. tumefaciens as in previous work with other plum rootstocks such as M.r.S.2/6 (Zoina & Raio 1999) and Torinel (Pinochet et al 2002). Bliss et al (2003) evaluated 20 Prunus species for their susceptibility to A. tumefaciens and found that resistant plants were identified in P. insititia.…”

“…Crown gall, which is caused by Agrobacterium tumefaciens E.F. Smith & Town, is distributed worldwide and is responsible for nursery and field losses among a large variety of plants, especially stone fruit trees (Pinochet et al 2002;Bliss et al 1999;Aysan et al 2004). No chemical pesticide is efficient against this bacterium, which multiplies in injured tissues causing a gall, which can occur any time during the plant's life.…”

Prunus rootstocks-GF677 (P. persica × P. amygdalus), Antafuel (P. amygdalus × P. persica), St. Julien 655/2 (P. insititia × P. domestica), Peach Seedling (P. persica), and Gisela 5 (P. cerasus × P. canescens)-were evaluated for their susceptibility to Agrobacterium tumefaciens. The results showed that no rootstock tested was immune. The St. Julien 655/2 rootstock was the most resistant of all tested, whereas no significant difference was observed between the other rootstocks. The level of susceptibility did not vary according to the strains used.
