“…The most common studies on genetic resistance in mango are related to anthracnose diseases (Bally et al, 2013), powdery mildew (Naqvi et al, 2014), mango malformation (Chakraborti and Misra, 2014), and mango wilt (Arriel et al, 2016). Works that evaluate resistance to dieback disease in mango, caused by fungi of the family Botryosphaeriaceae, are scarce.…”

“…In this sense, the selection of genotypes that show resistance to the development of the dieback disease of mango branches presumably reduce the endophytic and sequential development of these fungi from the mature branch to the inflorescence and pedicel (Johnson et al, 1992), consequently reducing stem-end rot. Arriel et al (2016) evaluated the inheritance of resistance to C. fimbriata in 197 mango genotypes from six families and reported that cultivars Keitt and Tommy Atkins were the most resistant, and cultivars Espada and Haden were the most susceptible to mango wilt. In the present study, cultivars Keitt, Haden, and Espada showed absence of symptoms higher than 94% in branches inoculated with L. theobromae, and 100% absence of symptoms in the material Batista et al (2012) reported that fruits of the 'Tommy Atkins' variety showed susceptibility to stem-end rot caused by N. parvum and F. aesculi.…”

“…Arriel et al (2016), in a pioneering study with six full-sib families, reported that resistance to Ceratocystis fimbriata, the causative agent of mango wilt disease, is polygenic with the prevalence of genes expressing dominance and epistasis. Studies in Florida, USA, have identified progenies originated from the crossing between 'Haden' and 'Sandersha' with no symptoms of the disease caused by the fungus Botryosphaeria ribis (anamorph: Neofusicoccum ribis), indicating that some cultivars are resistant to the pathogen (Ramos et al, 1997).…”

The fungi Lasiodiplodia theobromae and Neofusicoccum parvum are pathogens responsible for causing dieback disease in mangoes. Studies on the inheritance of resistance to these fungal diseases in mango are quite limited. The objective of the present study was to evaluate the inheritance of resistance to dieback disease in three pseudo-F 2 progenies to assist in mango breeding programs. Young branches containing young leaves were selected, and suspension of 10 3 conidia/mL of L. theobromae or N. parvum was sprayed separately. After inoculation, leaves were protected in a plastic wet chamber for 48 hours. The infection was estimated by taking the branches without symptoms/total number of inoculated branches. Plants without disease symptoms in more than 90% of the branches, in three different inoculation periods, were considered as resistant. Keitt, Haden, and Espada cultivars were resistant to both fungi, while 'Tommy Atkins' was susceptible to both pathogens. Monogenic resistance, conferred by recessive alleles, was observed for L. theobromae for the three crossings evaluated, despite the 13:3 segregation detected for 'Keitt' x 'Tommy Atkins'. For N. parvum, recessive resistance with 3:1 monogenic segregation was observed in the crossing 'Keitt' x 'Tommy Atkins', and 9:7 epistatic segregation was reported in the crossing 'Haden' x 'Tommy Atkins' and 'Espada x 'Tommy Atkins'. The mono or digenic inheritance observed in the present study indicates the possibility of selection in the F 2 generation and identification of plants with double resistance to L. theobromae and N. parvum in mango trees.

“…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
