“…In Europe, Sclerotinia trifoliorum is probably considered to be the main fungal threat and resistance screens have been developed (Marum et al 1994;Delclos et al 1997). Molecular markers have been developed to facilitate selection of resistant material (Page et al 1997).…”

Abberton, M. T., Marshall, A. H. (2005). Progress in breeding perennial clovers for temperate agriculture: centenary review. Journal of Agricultural Science, 143 (2-3), 117-135White clover (Trifolium repens L.) and red clover (T. pratense L.) are the most important legumes of temperate pastures. The former is used largely in systems based around sheep or cattle grazing and is grown together with a companion grass. Breeding aims to optimize the white clover contribution to the sward. This means that yield per se is not the aim but rather to take full advantage of the benefits of white clover; in particular, nitrogen fixation, high protein content, digestibility, mineral content and high intake. The objective is an agronomically and, as far as possible, nutritionally balanced sward, thus persistence of white clover and yield stability over a number of years are key goals. A considerable focus of germplasm improvement has therefore been overcoming biotic and abiotic stresses to clover performance. The former include not only pests and diseases but also the impact of the ruminant animal and the competitive interaction with the companion grass, while abiotic stress could be loosely defined as ?winter hardiness? and ?summer survival? depending on the site. In recent years the focus of many breeding efforts has shifted to give more consideration to the effects of variation within white clover germplasm on animal performance and the environment. Beneficial effects on productivity have been known for many years, but recent studies of the impact of forage diets on meat and milk quality have opened up new opportunities for improvement. Diffuse pollution of nitrogen and phosphorus from agricultural sources is high on the environmental protection agenda of many governments. Breeding efforts are now being made to reduce the contribution of clovers to both direct (leaching) and indirect (through animal returns) pollution. In particular, recent insights into mechanisms affecting protein breakdown in the rumen and silo offer new prospects for breeding interventions to reduce environmental impacts. Molecular marker methods are being developed in white clover and the transfer and use of resources and information accumulating in the model legumes Medicago truncatula and Lotus japonicus is likely to be a major route by which the power of genomic approaches is translated into forage legume improvement. Hybrids of white clover and related species have been developed to introgress key traits; namely, drought tolerance, grazing tolerance of large leaf types and enhanced seed yield, for which only limited genetic variation is present within the white clover gene pool. Red clover is less persistent than white clover, is typically cut three or more times in a season and is used to make silage for winter feed. Although it is often grown with a companion grass, monocultures are common and yield per se as well as persistency and pest and disease resistance are major breeding aims. Fewer agronomic studies and less germplasm improvement have bee...

“…1994). However, RAPD markers are generally inherent and useful in the germplasm in which they have been identified (Page et al 1997). Thus, it is important to transform the RAPD markers identified here to sequence characterized amplified regions (SCARs) or to develop allele-specific primers.…”

Fusarium vascular wilt in lentil: Inheritance and identification of DNA markers for resistance

et al. 1998

View full text Add to dashboard Cite

The inheritance of resistance to lentil (Lens culinaris Medik.) vascular wilt caused by Fusarium oxysporum f.sp. lentis was investigated in a cross between resistant (ILL5588) and susceptible (L692–16‐l(s)) lines. F2:4 progenies and F6:8, F6:9 recombinant inbred line (RIL) populations were assessed for their wilt reaction for three seasons in a well‐established wilt‐sick plot. Resistance to wilt was conditioned by a single dominant gene in the populations studied. The map location of the Fw locus was identified for the first time through linkage to a random amplified polymorphic DNA (RAPD) marker (OPK‐15900) at 10.8 cM. Two other RAPD markers (OP‐BH800 and OP‐DI5500) identified by bulked segregant analysis were associated in the coupling phase with the resistance trait, and another marker (OP‐C04650) was associated with repulsion. The DNA markers reported here will provide a starting point in marker‐assisted selection for vascular wilt resistance in lentil.

“…Although a natural decline in plant populations is typical for clover swards (Frame, Charlton, & Laidlaw, 1998), disease infestation, pest attacks, improper management, winter kill and poor competitiveness have all been reported as important factors leading to poor persistence (Boller et al, 2010;Taylor, 2008;Taylor & Quesenberry, 1996). In the 20th century, considerable efforts were made in red clover breeding programmes and research which aimed to improve red clover resistance to various fungal and virus diseases, pests and nematodes (Christensen, Koga, Tsukiboshi, & Uematsu, 1994;Coulman & Lambert, 1995;Delclos, Mousset-D eclas, & Raynal, 1997;Marum, Smith, & Grau, 1994;Page, Dulclos, Aubert, Bonavent, & Mousset-Declas, 1997;Quesenberry, Baltensperger, Dunn, Wilcox, & Hardy, 1989;Rufelt, 1985). Although forage production and disease resistance of many red clover cultivars have been improved considerably during the last decades (Marshall, Lowe, & Vale, 2012), persistency of cultivars remains an issue.…”

Dairy farmers have increased interest in multiyear red clover–ryegrass ley pasture swards because of their high productivity and protein concentration but the adoption of such mixtures has been restricted because of poor persistency of many red clover cultivars currently used. We aimed (i) to assess dry‐matter yield (DMY), persistence and nutritive value of four Mattenklee and four Ackerklee cultivars and (ii) to investigate the underlying plant morphological traits. We conducted a 4‐year field experiment with red clover–ryegrass mixtures, in combination with a short‐term pot experiment in which the red clover cultivars were grown both in monoculture and in mixture with Lolium perenne L. In the field, Mattenklees showed higher production (on average 42% higher) and clover content (on average 34% higher) in the third and fourth year of production compared to Ackerklees. In the fourth year, Mattenklees had slightly lower digestibility and lower protein concentration compared to Ackerklees cultivars; however, the digestible DMY and the protein yield were higher for Mattenklees. Both persistence and nutritive value of the different red clover cultivars were closely correlated with plant morphological traits. For stem length, there was close correlation (r > .77) between the results from the pot experiment and the field experiment, suggesting that stem length may be an important trait for plant breeding.
