چکیده

Fruit shape is one of the most important quality factors in many domesticated plants. In this study, we used bulked segregate analysis (BSA) to identify two sequence-related amplified polymorphism (SRAP) markers linked to fruit shape in cucumber (Cucumis sativus L.). A segregating F2 population of 130 plants from a cross (B-2-2×Y-3) of B-2-2 with long fruit shape trait and Y-3 with round fruit shape trait was used. Correlation and regression analysis showed that markers ME21/EM18M600 and ME9OD3M190 were linked closely to the allele of round at the fruit shape locus. Marker ME21/EM18M600 accounted for 49.5% of the phenotypic variation in fruit shape, and ME21/EM18M600 accounted for 33.1% of the phenotypic variation.

Pericarp polypeptides and SRAP markers associated with fruit quality traits in an interspecific tomato backcross.

The aim of this study was to detect polypeptides and genomic regions associated with fruit quality traits in a backcross generation using as parent the Argentinean cultivated tomato Caimanta of Solanum lycopersicum and the wild accession LA722 of S. pimpinellifolium. We tested two types of molecular marker: polypeptide profile (at two ripening stages, mature green and red ripe) and SRAP (sequen...

Analysis of genetic diversity between and within Iranian accessions of spinach (Spinacia oleraceae) by SRAP markers

Spinach (Spinacia oleracea L.) is an economically important leafy vegetable crop in many countries. This is the first case study of using SRAP markers to analyze genetic diversity of Iranian spinach accessions. Eight SRAP primer combinations generated 88 scorable bands ranging from 50 to 1000 bp, among which 73 were polymorphic, with an average of 82.9 polymorphic bands per primer combination a...

Genetic Variation of Lime (Citrus sp.) Accessions Using Flow Cytometry Technique, Morphological Characteristics and Molecular Markers

Because of sexual propagation of Mexican lime in southern regions of Iran, there are many lime accessions (lime biotypes) in Mexican lime gardens in which appear some variation in fruit and tree shape. However, most of these accessions are susceptible to witches broom disease of lime (WBDL). Persian lime (C. latifolia Tanaka) is a triploid WBDL-tolerant species. Considerable number of un-descri...

Identification of new SRAP markers linked to leaf chlorophyll content, flag leaf senescence and cell membrane stability traits in wheat under water-stressed condition

A segregating F4 population from the cross between drought sensitive (Yecora Rojo) and drought tolerant (Pavon 76) genotypes was made to identify SRAP markers linked to leaf chlorophyll content, flag leaf senescence and cell membrane stability traits in wheat (Triticum aestivum L.) under water-stressed condition. The parents and 150 F4 families were evaluated phenotypically for drought toleranc...

Using two retrotransposon-based marker systems (SRAP and REMAP) for genetic diversity analysis of Moroccan Argan tree

The Argania is an endemic genetic resource in Morocco holding an important ecological and socio-economical benefit. However, overgrazing and overharvesting lead to a serious downturn in the number of trees. To characterize genetic diversity within and among 24 populations, represented by 240 argan trees, four combinations of SRAP primers and eight combinations of REMAP primers were used. A tota...
