Genetic Diversity of Phenotypic and Biochemical Traits in VIR Radish ( L.) Germplasm Collection.

Small radish and radish are economically important root crops that represent an integral part of a healthy human diet. The world collection of L. root crops, maintained in the VIR genebank, includes 2810 accessions from 75 countries around the world, of which 2800 (1600 small radish, 1200 radish) belong to species, three to , three to , and four to .

Effects of Genotype and Culture Conditions on Microspore Embryogenesis and Plant Regeneration in ssp. L.

Turnip is a biennial crop and, consequently, the creation of pure lines for breeding is a time-consuming process. The production of pure turnip lines using doubled haploids produced in isolated microspore culture has not been sufficiently developed. The aim of the present work was to determine some key factors inducing embryogenesis in the isolated microspore culture of turnip, as well as investigating the manners of embryo development.

Phenotypic and genetic analysis of the Triticum monococcum-Mycosphaerella graminicola interaction.

Here, the aim was to understand the cellular and genetic basis of the Triticum monococcum-Mycosphaerella graminicola interaction. Testing for 5 yr under UK field conditions revealed that all 24 T. monococcum accessions exposed to a high level of natural inocula were fully resistant to M.

Identification of variation in adaptively important traits and genome-wide analysis of trait-marker associations in Triticum monococcum.

Einkorn wheat Triticum monococcum (2n=2x=14, A(m)A(m)) is one of the earliest domesticated crops. However, it was abandoned for cultivation before the Bronze Age and has infrequently been used in wheat breeding. Little is known about the genetic variation in adaptively important biological traits in T.

The use of conventional and quantitative real-time PCR assays for Polymyxa graminis to examine host plant resistance, inoculum levels and intraspecific variation.

* A real-time PCR protocol based on 18S rDNA sequences was developed to provide a specific, sensitive and quantitative assay for the root-infecting virus vector Polymyxa graminis. * The assay was calibrated with zoospore suspensions and inoculated roots and then shown to work with naturally infected plant roots and infested soil. Both the temperate P.
