Phenotypic evaluation of Trifolium repens × Trifolium uniflorum F1 interspecific hybrids as predictors of BC1 hybrid progeny A thesis presented in partial fulfilment of the requirements for the degree of Master of Science In Plant Breeding at Massey University, Palmerston North New Zealand Michelle Anne Ebbett 2017 1 i Abstract Interspecific hybrids between white clover (Trifolium repens) and its close relatives are being created to address the lack of variation within white clover for traits relating to persistence and drought tolerance. This study addresses two concepts related to developing hybrid breeding strategies using Trifolium repens x Trifolium uniflorum hybrids. A first sandframe experiment investigated whether some of the first generation hybrid plants (F1) with common parents were better than others as future parents. A second experiment assessed whether the performance of the first back cross (BC1) progenies could be predicted from the parental F1 phenotypes. The foliage, fertility, roots and dry weight production of four families of F1 hybrids were evaluated following a period of growth in sand. From each family, the F1 hybrids with the highest and lowest dry weight production were selected and back crossed to two contrasting white clover cultivars. The resulting BC1 hybrid phenotypes were evaluated to ascertain whether any F1 hybrids were markedly better as future parents in hybrid breeding programmes, and whether the F1 phenotype could be used to predict that of the BC1 progeny. -

Testing alternative breeding methods in white clover A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University by Richard Mark George Lincoln University 2014 Abstract of a thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy. Testing alternative breeding methods in white clover by Richard Mark George A series of experiments were conducted to estimate the genetic parameters for an elite breeding population of white clover (Trifolium repens L.) in both an irrigated and dryland environment. Data collected from two environments using spaced-planted and mini-plot trials were used to demonstrate the rationale for pursing various traditional and modern marker- assisted selection breeding methods in white clover. In addition, and under the over-arching theme of investigating breeding strategies, supplementary findings are presented regarding pollination patterns within a white clover population in isolation cages. In an experiment designed to generate half-sib and full-sib families for progeny evaluation, pollen dispersal within isolation cages using wild bumble bees (Bombus sp.) was monitored using simple sequence repeat molecular markers (SSR markers). -
Genetic Transformation of Western Clover (Trifolium Occidentale D. E
Richardson et al. Plant Methods 2013, 9:25 http://www.plantmethods.com/content/9/1/25 PLANT METHODS METHODOLOGY Open Access Genetic transformation of western clover (Trifolium occidentale D. E. Coombe.) as a model for functional genomics and transgene introgression in clonal pasture legume species Kim A Richardson1*, Dorothy A Maher1,2, Chris S Jones1,2 and Greg Bryan1 Abstract Background: Western clover (Trifolium occidentale) is a perennial herb with characteristics compatible for its development as an attractive model species for genomics studies relating to the forage legume, white clover (Trifolium repens). Its characteristics such as a small diploid genome, self-fertility and ancestral contribution of one of the genomes of T. repens, facilitates its use as a model for genetic analysis of plants transformed with legume or novel genes. Results: In this study, a reproducible transformation protocol was established following screening of T. occidentale accessions originating from England, Ireland, France, Spain and Portugal. The protocol is based upon infection of cotyledonary explants dissected from mature seed with the Agrobacterium tumefaciens strain GV3101 carrying vectors which contain the bar selection marker gene. Transformation frequencies of up to 7.5% were achieved in 9 of the 17 accessions tested. Transformed plants were verified by PCR and expression of the gusA reporter gene, while integration of the T-DNA was confirmed by Southern blot hybridisation and segregation of progeny in the T1 generation. Conclusions: Development of this protocol provides a valuable contribution toward establishing T. occidentale as a model species for white clover. This presents opportunities for further improvement in white clover through the application of biotechnology. -
A Guide to Frequent and Typical Plant Communities of the European Alps
- Alpine Ecology and Environments A guide to frequent and typical plant communities of the European Alps Guide to the virtual excursion in lesson B1 (Alpine plant biodiversity) Peter M. Kammer and Adrian Möhl (illustrations) – Alpine Ecology and Environments B1 – Alpine plant biodiversity Preface This guide provides an overview over the most frequent, widely distributed, and characteristic plant communities of the European Alps; each of them occurring under different growth conditions. It serves as the basic document for the virtual excursion offered in lesson B1 (Alpine plant biodiversity) of the ALPECOLe course. Naturally, the guide can also be helpful for a real excursion in the field! By following the road map, that begins on page 3, you can determine the plant community you are looking at. Communities you have to know for the final test are indicated with bold frames in the road maps. On the portrait sheets you will find a short description of each plant community. Here, the names of communities you should know are underlined. The portrait sheets are structured as follows: • After the English name of the community the corresponding phytosociological units are in- dicated, i.e. the association (Ass.) and/or the alliance (All.). The names of the units follow El- lenberg (1996) and Grabherr & Mucina (1993). • The paragraph “site characteristics” provides information on the altitudinal occurrence of the community, its topographical situation, the types of substrata, specific climate conditions, the duration of snow-cover, as well as on the nature of the soil. Where appropriate, specifications on the agricultural management form are given. • In the section “stand characteristics” the horizontal and vertical structure of the community is described. -

Due to sea fog around the coast the flights to Scilly had been cancelled. Fortunately for the five people planning to fly to Scilly there was just time for them to be transferred by road to Penzance in time for RMS Scillonian’s second sailing of the day. The second sailing was unusual due to the huge number of people who had been on the Isles of Scilly for the Pilot Gig Weekend. Gig Weekends have become extraordinarily popular, with the 2018 season the biggest yet; 150 gig boats, their six rowers plus cox and many supporters were on Scilly to watch or participate in the races. Crews had come from south-west England, and as far away as Holland and United States, and most had brought their friends! Five clients were also booked on the ferry and some met up there with Rosemary. -

Morphological and anatomical studies on mountain clover (Trifolium montanum) (Fabaceae) from Sharri Mountain, Kosovo 1Kimete Lluga-Rizani, 2Dubravka Šoljan, 1Kemajl Kurteshi, 1Kasum Letaj 1 Department of Biology, Faculty of Mathematical Natural Sciences, University of Prishtina, Kosovo; 2 Department of Biology, Faculty of Mathematical Natural Sciences, University of Sarajevo. Corresponding author: K. Lluga-Rizani, [email protected] Abstract. The object of our research was Trifolium montanum (Linnaeus, 1758). The aim was to ascertain the level of morphological variability between different populations, and put more light on taxonomy of this species. The research was carried out on the vertical profile of Sharri Mountain, Kosovo. One part of the collected plant material was dried and placed in herbarium, whereas the other part was preserved in alcohol of 70% for preparation of microscope slides. A comparative-morphometric method was used to evaluate the morphological variability of individuals and populations. For examination of variability of stomatal apparatus, trichome length, vascular bundle diameter, palisade and sponge cell lengths, SWIFT M10L SERIES microscope with a measurement software, was used. 26 morphological traits have been investigated. From the results obtained during this research it can be concluded that there is significant difference between 10 locations from Sharri Mountain for most of micro and macro morphological traits. Also the results lead to the suggestion for the taxonomic revision of this taxon. Key Words: morphological variability, Trifolium montanum, locations, taxonomic revision.
