“…Genetic variability for resistence to Ceratocystis wilt has also been described in other species as Mangifera indica (RIBEIRO et al, 1984;RIBEIRO et al, 1986;RIBEIRO et al, 1995;ROSSETTO et al, 1997), Coffea arabica (CASTILLA, 1982) and Crotalaria spp. (RIBEIRO et al, 1977).…”

Ceratocystis wilt, caused by Ceratocystis fimbriata, is one of the most damaging diseases in eucalyptus plantations worldwide. Although there are resistant genotypes, the genetic basis of resistance is still poorly understood. In this paper we studied the resistance level by a stem inoculation experiment of genotypes of Eucalyptus grandis and E. urophylla and estimated the heritability and gains of selection in families derived from controlled interspecific crosses. In both species, highly resistant as well as highly susceptible genotypes to Ceratocystis wilt were found. Out of 21 parents assessed, twelve were resistant and nine susceptible. Estimates of individual narrow (50 %) and broad (59 %) sense heritability suggested a high degree of genetic control and low allelic dominance of the trait. There was great genetic variation among and within families, a fact that contributes to high heritability and genetic gain. A genetic gain in lesion size of up to -74.4 % was obtained from selection of the 50 best clones in the evaluated families, i.e., the mean lesion length in the progeny population can be reduced by 74,4 %.

“…Some rootstocks are able to buffer the trees against saline and calcareous soils and poor quality irrigation waters (Kadman et al, 1976;Gazit and Kadman, 1980;Pandey et al, 2014). There are others that are resistant to diseases such as mango wilt caused by the fungus Ceratocystis fimbriata (Rossetto et al, 1997;Arriel et al, 2016). In studies conducted in northern Australia with rootstocks from 95 poly-embryonic cultivars there was no clear relationship between dwarfing in the field and the vigour of the trees in the nursery (Bithell et al, 2016).…”

Can the productivity of mango orchards be increased by using high-density plantings?

a b s t r a c tMango (Mangifera indica) trees are traditionally established at about 100-200 trees per ha and eventually grow into large specimens 10 m tall or more, making spraying and harvesting difficult. It also takes a long time to recover the initial costs of establishing and maintaining the orchard. There has been considerable interest in planting orchards up to 4000 trees per ha to take advantage of early production and to increase economic returns. However, trees planted at high density soon begin to crowd and shade each other and production falls. We reviewed the performance of high-density orchards in different growing areas, and the role of dwarfing cultivars and rootstocks, tree canopy management and the growth regulator, paclobutrazol to control tree growth. There has been no general agreement on the optimum planting density for commercial orchards which vary from 200-4000 trees per ha in different experiments. Some potential dwarfing material has been developed in India and elsewhere, but these cultivars and rootstocks have not been widely integrated into high-density orchards. Canopy management needs to take into account the effect of pruning on the regrowth of the shoots and branches, light distribution through the canopy and the loss of the leaves that support the developing crop. Pruning must also take into account the effect of vegetative growth on flower initiation. Annual light pruning usually provides better fruit production than more severe pruning conducted less regularly. There have only been a few cases where it has been demonstrated that paclobutrazol can counteract the negative effect of pruning on flowering and fruit production. There are also concerns with residues of this chemical in export markets and contamination of ground waters. The future development of high-density plantings in this crop is dependent on the use of dwarfing cultivars and/or rootstocks and better canopy management strategies. Dwarfing cultivars and rootstocks should provide small-to medium-sized trees with medium to large yields. This can readily be identified in experiments by examining the relationship between yield and tree growth. Research on canopy management should assess the impact of pruning on flowering, light distribution within the canopy and the leaf area supporting the developing crop. The productivity of mango is not likely to be increased by the use of high-density plantings without extensive efforts in plant breeding and canopy management.Crown

“…Due to this figures, efforts are been made by breeders to overcome difficulties. There are at least three different mango breeding programs in Brazil: at Embrapa Cerrados, Embrapa Cassava and Fruit Crops, and at the Agronomic Institute of Campinas (IAC) (Rossetto et al, 1997). Embrapa Cerrados studied fruit set success or compatibility among three genotypes: 'Tommy Atkins' and the Indian cultivars Amrapali and Mallika.…”

“…The cultivar Votupa showed high percentage of pulp, which was similar to the commercial cultivars Van Dyke, Tommy Atkins and Palmer (Rossetto et al, 2002). Mango breeding program for resistance to diseases and pests of the Instituto Agronômico de Campinas (IAC) (Rossetto et al, 1997) has two main objectives: (1) to obtain polyembrionic rootstocks resistant to the fungi Ceratocystis fimbriata which causes the mango-wilt. The first cultivar derived from this program, named IAC 100 Bourbon, was distributed to farmers on December 8, 1989.…”

ABSTRACT-Brazil is a very large country with a diverse climate. This fact allows a diversity of plants to grow ranging from tropical rainforest in the Amazon, passing through Atlantic Forest along the coast, the cerrados (Brazilian savannah) in the Central West region, and semi-arid area in the Northeast. Latitude ranges from 5° N to 33° S, with most of this territory in the tropical region. There are enough reasons to plant breeders devoting great amount of their effort to improve plants suitable for warm climates, though. Among fruit crops, results of breeder's work have been noticed in several species, especially on peaches, grapes, citrus, apples, persimmons, figs, pears and others not so common, such as acerola, guava, annonas (sour sop, sugar apple, atemoya, cherimoya) and passion fruit. Peach tree introduced at low latitude (22 ± 2ºS) requires climatic adaptation to subtropical conditions of low chilling. In Brazil, the first peach breeding program aiming adaptation of cultivars to different habitats was developed by Instituto Agronômico de Campinas (IAC) beginning in the end of the 40's. Apple low chill requirement cultivars obtained in a South state, Paraná, are now been planted at low latitudes. Banana and pineapple breeding programs from Embrapa units along the country are successfully facing new sanitary problems. Petrolina/Juazeiro, in the Northeastern region (9°S), is the main grape exporting region with more than 6,000 ha. Grape growing in the region is based in the so called "tropical" rootstocks released by IAC, namely: IAC 313 'Tropical', IAC 572 'Jales'. Recently, Embrapa Grape and Wine released tropical grape seedless cultivars that are changing table grape scenario in the country. Index Terms: temperate fruits, tropical fruits, tropical and subtropical climates, productivity. O IMPACTO DO MELHORAMENTO GENÉTICO NA PRODUÇÃO DE FRUTAS EM CLIMAS QUENTES DO BRASILRESUMO-O Brasil, com suas dimensões continentais, apresenta grande diversidade de climas. Este fato permite o crescimento de grande diversidade de plantas desde a floresta tropical úmida do Amazonas, passando pela Mata Atlântica ao longo da costa, os cerrados, na região centro-oeste e nas áreas de semiárido no nordeste. A maior parte do território encontra-se na região tropical onde a latitude abrange de 5° N a 33° S. Há, portanto, razões suficientes para os melhoristas de plantas devotarem boa parte de seus esforços para melhorar plantas apropriadas aos climas mais quentes. Entre as frutíferas, os resultados dos trabalhos dos melhoristas têm sido notados em diversas espécies, especialmente pêssegos, uvas, citros, maçãs, caquis, figos, pêras e outras, não tão comuns, como acerola, goiaba, anonas (graviola, pinha, atemóia, cherimóia) e maracujá. Pessegueiros introduzidos em baixas latitudes (22 ± 2ºS) requerem adaptação climática às condições subtropicais de baixa ocorrência de frio. No Brasil, o primeiro programa de melhoramento de pêssego visando adaptação de cultivares a diferentes habitats foi desenvolvido pelo Instituto Agronômico de...
