Bruchid pest management in pulses: past practices, present status and use of modern breeding tools for development of resistant varieties
Abstract
Bruchids (Callosobruchus spp.) are recognised as the most detrimental storage pest of pulses, especially in the tropics and subtropics. They invade matured pods as well as seeds during storage and, to some extent, farming fields, in turn reducing the net yield of the crops. Several approaches including cultural, biological, physical and chemical control measures have been implemented with the aim of managing these pests, but none of these have been successful across time and space. Recently, transgenic‐ and marker‐assisted breeding approaches have appeared as promising tools for the successful management of th...

Wolbachia infection in natural populations of Dictyophara europaea, an alternative vector of grapevine Flavescence dor ée phytoplasma: effects and interactions
In this study we present findings on a heavily FDp‐infected D. europaea population (>60%), on the natural Wolbachia infection of populations with low FDp‐infection rates (DeWo+) and on Wolbachia absence in highly FDp‐infected population (DeWo−). We examine several possible causes underlying the differences in vector infection rates: (a) population genetic characteristics of D. europaea and correlation with Wolbachia strain wEur natural infections, (b) Wolbachia effects on fitness components of DeWo+ laboratory colony and (c) rate of reservoir plant FDp‐infection and differences in FDp genotypes harboured by lo...

Distribution and diversity of begomoviruses in tomato and sweet pepper plants in Costa Rica
This study aimed to analyse the diversity and distribution of begomoviruses in tomato and sweet pepper fields of the major growing regions of Costa Rica. From 651 plants randomly sampled from greenhouses and open fields during 2011 and 2012, four begomoviruses were detected for which full length genome sequences were obtained: Tomato yellow mottle virus (ToYMoV), Tomato leaf curl Sinaloa virus (ToLCSiV), Pepper golden mosaic virus (PepGMV), and Tomato yellow leaf curl virus (TYLCV). Their distribution and prevalence varied largely depending on the geographical location, the host and the production system, with detection ra...

Mode of action and efficacy of iprodione against the root ‐knot nematode Meloidogyne incognita
Abstract
The ban and restriction on the use of several synthetic chemicals for controlling plant parasitic nematodes, and concern about their side effects necessitate the availability of effective methods of control with low toxicity to humans and non‐target organisms. Therefore, efficacy and mode of action of iprodione, a dicarboximide fungicide, was evaluated against the root‐knot nematode Meloidogyne incognita, in vitro and in vivo conditions, in comparison with the nematicides fenamiphos, fosthiazate and oxamyl at 7.00, 1.66 and 1.66 mL/5 L water, respectively. In vitro, iprodione showed nematostatic rather than ne...

A discussion on disease severity index values. Part II: using the disease severity index for null hypothesis testing
The objective of this work is to explore the effects on both of different scales (i.e. those having equal or unequal classes, or different widths of intervals) and of the selection of values for scale intervals (i.e. the ordinal grade for the category or the midpoint value of the interval) on the null hypothesis test for the treatment comparison. A two‐stage simulation approach was employed to approximate the real mechanisms governing the disease‐severity sampling design. Subsequently, a meta‐analysis was performed to compare the effects of two treatments, which demonstrated that using quantitative ordinal rating gra...

Analysis of the genetic diversity and structure of the Spanish apple genetic resources suggests the existence of an Iberian genepool
This study is the first valuable action for genetic conservation of apple at the national scale, and constitutes a decisive step towards the definition of a Spanish core collection that will be useful for further studies in dissecting the genetic control of important horticultural traits through genome‐wide association analysis in apple.
In this study, 1453 apple accessions were characterized with 13 SSR markers in order to evaluate the genetic diversity and to unravel the structure in the Spanish germplasm. 737 unique genotypes were identified (581 diploids and 156 triploids). Two reconstructed populations were obtaine...

Phenological growth stages of mulberry tree (Morus sp.) codification and description according to the BBCH scale
Abstract
Recently, mulberry fruits have increased rapidly the production and consumption, due to its high levels of bioactive compounds, excellent taste and nutritional value. Nevertheless there is poorly information about its phenology. In the present study, the different phenological growth stages of mulberry are characterised according to the BBCH (Biologische Bundesanstalt, Bundessortenamt Chemische Industrie) scale. Eight of the 10 principal developmental stages from BBCH scale were described for Morus sp., starting at bud development (stage 0) and ending at the senescence and beginning of the rest period (stage 9). T...

Aspects in oat breeding: nutrition quality, nakedness and disease resistance, challenges and perspectives
Abstract
Traditionally, the oat crop (Avena sativa) has been neglected in a number of respects, cultivated in cropping areas not optimal for wheat, barley or maize. In recent years the interest in oats has increased, particularly because of its dietary benefits and therapeutic potential for human health. The uniqueness and advantages of naked oats over other popular cereals, due to its potentially valuable nutritional composition, have been well studied and reported, opening new market “niches” for oats. Despite the well‐documented benefits, the status of the oat crop is still fragile, due to many reasons. The area c...

Antioxidant system is essential to increase drought tolerance of sugarcane
Abstract
Drought is one of the main factors affecting the productivity of agricultural crops, and plants respond to such stress by activating various physiological and biochemical mechanisms against dehydration. The present study investigated two varieties of sugarcane (Saccharum spp.) with contrasting responses to drought (RB867515, more tolerant; and RB855536, less tolerant) and subjected them to progressive drought conditions (2, 4, 6 and 8 days) followed by rehydration. Drought caused a decrease in water potential (ψw) and osmotic potential (ψos) in the leaves, which recovered to normal levels after rehydration onl...

Effect of tillage, subsidiary crops and fertilisation on plant ‐parasitic nematodes in a range of agro‐environmental conditions within Europe
Abstract
The overall goal in nematode management is to develop sustainable systems where nematode populations are kept under the economic damage threshold. Conservation tillage and subsidiary crops, applied as cover crops and living mulches, generally improve soil health by increasing soil organic matter content and stimulating soil microbial activity. However, more permanent crop and weed cover associated with subsidiary crops and noninversion tillage, respectively, may benefit plant‐parasitic nematodes with broad host spectra such as Meloidogyne and Pratylenchus. These genera are major constraints to many field crops t...

Comparative analysis of core collection sampling methods for mandarin germplasm based on molecular and phenotypic data
In this study, several software packages (DARwin, PowerMarker and MSTRAT) and methods (Max length subtree, M strategy, simulated annealing and MinSD) were compared to define a mandarin (Citrus reticulata) CC. One hundred and sixty‐seven accessions were sampled from two germplasm collections, which were genotyped with 50 SSR, 24 InDel and 68 single nucleotide polymorphism markers. All the CC obtained were tested for the maintenance of the genetic variability parameters (Ho and He) of the initial collection, the level of linkage disequilibrium (LD) and the phenotypic diversity retention. The Max length subtree function fro...
