Russian wheat aphid: a model for genomic plasticity and a challenge to breeders

Insect Science, EarlyView.
Invasive foundress finds suitable habitat and reproduces through pathogenesis. Wingless females produce life offspring quickly, which leads to high population densities. High population densities result in competition, which may induce epigenetic changes and wing development for dispersal.

TRADITION, QUALITY AND BIOTECHNOLOGY IN HUNGARIAN SPICE PEPPER (Capsicum annuum L.) BREEDING

, 2010
Spice pepper production has a history of almost 300 years in the southern part of Hungary. In this study the results of two biotechnological improvements are summarized. Anther and isolated microspore culture techniques were improved to release haploid

Wheat flour protein content and water absorption analysis in a doubled haploid population

, 2007
A wheat×maize induced doubled haploid population that segregates at the Awned locus for awned and awnless phenotypes were studied at two field sites using a genetic linkage map.

The use of deidentified organ donor testes for research

Andrology, EarlyView.
Abstract Our knowledge of testis development and function mainly comes from research using mammalian model organisms, primarily the mouse. However, there are integral differences between men and other mammalian species regarding cellular composition and expression profiles during fetal and post‐natal testis development and in the mature testis ...

Genotyping of Anatolian doubled-haploid durum lines with SSR markers

, 2001
In this study, doubled haploid lines generated from the durum wheat varieties, selections from Middle Anatolian landraces, 'Cakmak-79', 'Berkmen-469' and 'Kunduru-1149' (Savaskan et al., 1997), were analyzed using ten highly polymorphic microsatellite ...

Overview of In Vitro and In Vivo Doubled Haploid Technologies

, 2021
International audienceDoubled haploids (DH) have become a powerful tool to assist in different basic research studies, and also in applied research. The principal (but not the only) and routine use of DH by breeding companies is to produce pure lines for

An evaluation of some morphological traits in doubled haploid cabbage (Brassica oleracea var. capitata L.) lines and their F1 hybrids

Acta Agriculturae Slovenica, 2002
Fifty - four doubled haploid lines produced via androgenesis and self-pollination were analysed in a field trial, as well as some of their hybrids. Based on statistical evaluation, 17 lines with favourable morphological traits (head weight, proportion ...

Anatomical and Histological Descriptions of the Male Reproductive System of the Alfalfa Weevil of Hypera postica (Gyllenhal, 1813) (Coleoptera: Curculionidae) Using Light and Scanning Electron Microscopies

Acta Zoologica, EarlyView.
ABSTRACT Features of the reproductive organs, such as the number of testicular follicles, testis colour and the morphology of the glands, can be used as systematic characters. For this purpose, this paper was the first description of the male reproductive system anatomy and histology of Hypera postica (Gyllenhal, 1813) (Coleoptera: Curculionidae), a ...
