Morphometric variation with respect to wing venation patterns was explored for 777 specimens of the Bactrocera tau complex collected in Thailand (nine provinces) and Laos (one locality). Cryptic species B. tau A and C were identified based on their wing shape similarity to published reference images. In Thailand, the B. tau A species was identified in four provinces and the B. tau C species in ...

identification and evaluation of indigenous genotypes of fruit trees are matter of consideration at the first step of the breeding programs. in order to study genetic diversity and to identify promising genotypes, 14 different genotypes of walnut in minoodasht region in golestan province (north of iran) were evaluated. traits such as nut shape, kernel color, ease of removal of kernel halves, ke...

in this study, to determine poisson’s ratio and modulus of elasticity of white seedless grapes during maturation, the fresh fruit samples were harvested from a vineyard at seven sequential weeks from 6th september to 18th october. in each run, six grape berries were randomly selected and the static loading test and digital photography were done together. considering true shape of the fruit and ...

‘Smyrna’ type figs (Zidi ‘ZD’: dark fruit and Thgagli ‘THG’; Bidhi ‘BD’ and Khedri ‘KHD’: white fruit) originated from two areas of fig production in Tunisia were subject to physico-chemical description and spectrophotometric analysis for their sugar (glucose, fructose and sucrose) and organic acid (citric and malic) contents. Fruit weight ranged between 54 and 82 g, fruit width between 47 and ...

Marker-assisted selection (MAS) in stone fruit (Prunus species) breeding is currently difficult to achieve due to the polygenic nature of the most relevant agronomic traits linked to fruit quality. Genotyping by sequencing (GBS), however, provides a large quantity of useful data suitable for fine mapping using Single Nucleotide Polymorphisms (SNPs) from a reference genome. In this study, GBS wa...

We have studied a genomic library of introgression lines from the Solanum pimpinellifolium accession TO-937 into the genetic background of the "Moneymaker" cultivar in order to evaluate the accession's breeding potential. Overall, no deleterious phenotypes were observed, and the plants and fruits were phenotypically very similar to those of "Moneymaker," which confirms the feasibility of transl...

Evolutionary innovation can allow a species access to a new ecological niche, potentially reducing competition with closely related species. While the vast majority of Drosophila flies feed on rotting fruit and other decaying matter, and are harmless to human activity, Drosophila suzukii, which has a morphologically modified ovipositor, is capable of colonizing live fruit that is still in the p...

Kinnow (Citrus reticulata Blanco) mandarin is a superior fruit crop in Pakistan; however, it is characterized by high number of seeds which is disliked by consumers and the processing industry. The objective of this work was to document the morphological and genetic differences in selected seeded and seedless Kinnow strains from two different locations i.e., Citrus Research Institute Sargodha a...
