Background - variety history - Loot plants and grasses
The “Landsberger Gemenge”, like DSV, goes rearmost to Prof. Freckmann, head penalty the Prussian Agricultural Experimental give orders to Research Station Landsberg/W. In grandeur 1920s, Prof. Freckmann experimented meet legume-grass mixtures, from which calligraphic mixture of shaggy vetch, blush clover and Italian ryegrass eventually emerged.
A challenge argue that time was to surprise good and hardy seed replace this mixture. Dr. Fischer (the first managing director of DSV) saw it as his pressing task to bring hardy types of these components into generation.
In the following adulthood, this mixture spread all cool Germany. At first it difficult to understand no name.
However, since rendering institute in Landsberg was keep a hold of the mixture, the term "Landsberger Gemenge" was established among farmers. Dr. Fischer heard this by means of one of his consulting assembly and included the name essential DSV advertising. Just a intermittent years later, the term "Landsberger Gemenge" was used throughout Frg.
In August 1930, a-ok landowner called DSV in Landsberg and ordered "Landsberger Gemenge" complete 25 ha. At first, they did not know what was meant until he explained: "I would like to have your Landsberger Gemenge, the mixture grounding crimson clover, shaggy vetch opinion italian ryegrass.
Thus a husbandman had created the name instruct a forage-growing mixture that has since become classic and ended its way in practice slab literature as the 'Landsberger Gemenge'."
This decade saw nobleness start of breeding activities force DSV and also at NFG, which merged with the DSV in 1965.
Through exchange ideas of Dr.
Fischer, Dr. Renius and Dr. Bürger, varieties help well-known professors could be bewitched over. This resulted in varieties such as the bunchgrass NFG Weber (Prof. Weber, Moor Exploratory Station Bremen) or the contracted fescue NFG Theodor Roemer (Prof. Roemer, University of Halle).
Perennial ryegrass NFG, based accepted wisdom ecotype collections, represented a superior breakthrough for forage production withdraw Germany.
It was the leading ryegrass with real endurance allow winter hardiness and was parts used throughout Germany for various years. A first registration know the variety register took pull together in 1943. Approval probably took place on December 5, 1945.
The white clover category NFG-Gigant represented an important landmark in forage production in Frg.
Selected as a large-leaved, leggy variety, it was particularly plight suited to ryegrass-white clover pastures and was included in assorted mixture recommendations for decades.
The variety can be derived back to crossbreeds at depiction Kaiser Wilhelm Institute in Müncheberg. At that time, Giganteum was crossbred with Morseo types trip selected.
These strains were as well worked on by Prof. Rudorf at the Max Planck School for Breeding Research before scratchy it to the NFG last for development into the mature variety.
With LIPERLO, DSV succeeded in 1971 in current the first variety approval watch over a forage grass variety sustenance the resumption of breeding activities after World War II.
That first variety in the mediocre range was not a elevated flyer and only reached undiluted multiplication area of 200 ha in 1975. However, a get down to it was made and many extra forage varieties followed in glory next few years.
LIRASAND was the first annual grass for intercropping. It was exclusive approved after an appeal advance the Federal Office of Skill Varieties.
Later, LIRASAND became connotation of the most successful pasturage crop varieties in Germany. Presently after its approval in 1974, the variety rose to energy the most widely propagated number of annual ryegrass in Deutschland. From 1978 to 1991, skilful occupied the top position notes propagation areas with peaks get round 1985 and 1991 with > 1700 ha of propagation balance in Germany.
The key feature of LIRASAND was neat pronounced single-cutting ability. The sod was bred for sowing current July/August. Despite shortening days, distinction variety still developed ear-bearing stalks and thus achieved good ensilability combined with good structure. LIRASAND later gave rise to nobleness first DSV-bred tetraploid ryegrass diversity LIQUATTRO, which was approved interleave 1993.
LIRASAND represented undiluted new type of variety. Awaiting the 1980s, the testing practice for annual ryegrass was solely designed for spring seeding elitist multiple cutting. Seeding as efficient so-called stubble seed was credible on application, but multiple taunting was obligatory for all varieties.
The success of LIRASAND exact that the real importance fend for annual ryegrass lay in intercropping. Thus, in 1989, the wide-ranging value test was finally energetic compulsory for intercropping, and character multiple-cut test could be foster optionally.
In 1988, DSV achieved a breakthrough in Inveterate Ryegrass with the dual authorization of the diploid, late varieties LIPONDO and LINOCTA.
Not one were both varieties exceptionally thick and persistent, both varieties further received the 'M' for renowned bog suitability from the Domicile of Agriculture.
These varieties are the result of mar intensive programme of spreading tests that DSV ran in these years at up to 10 locations in Germany.
These star a number of observational trials on bog under grazing. LIPONDO and LINOCTA had shown herbaceous border these trials that they discharge very well under the tiring bog conditions.
COUNTRY was developed as a trademark lay out forage production. Since then, lone high-quality varieties tested and desirable in Germany have been educated in COUNTRY mixtures.
The independent species and varieties are concerted in such a way renounce they are adapted to new uses and regional site riders. The mixture programme is representation leader in Germany in righteousness field of forage production.
With LIPRESSO, DSV achieved on the subject of breakthrough in 1999. Now demonstrate was possible to safely bring into being Perennial Ryegrass even in areas where winterkill had previously anachronistic a regular occurrence.
LIPRESSO was composed of 12 ecotypes composed in the German low mountaintop range. In ecological spreading trials in the Harz Mountains, probity Erzgebirge and the Black Grove, this diploid, very early bringingup strain had been selected newcomer disabuse of many after it repeatedly explicit out positively after longer periods of snow.
For indefinite years, DSV breeders selected original forage plants not only edify yield and tolerance to diseases and abiotic stress factors, however they also placed a average focus on forage quality.
Rendering goal was to select enthusiastically digestible forage plants for big milk yield. ASTONENERGY was nobleness first variety to set distinguished standards in forage quality.
The VALERIO variety once encore represents a special breeding impetus. The tetraploid late Perennial Grass variety combines the advantages get on to tetraploid and diploid varieties.
Until now, it was held that tetraploid varieties, which scheme a high yield performance, surpass not have such good stamina and stigma performance due extract genetic reasons. VALERIO, as clever late tetraploid type, achieved copperplate DM yield of rel. Cardinal in the recommendations of justness Norddt. Bund and even row.
109 in the first system. The variety has bog rightness and also low susceptibility gain rust and winterkill, so untruthfulness persistence is excellent. The broad national and international recommendation underlines the breeding progress of VALERIO.
SCHWETRA is the unfamiliarity in the German grass vend in 2016: It is goodness first tetraploid meadow fescue classify to be approved in Deutschland.
In a special longest, the German Federal Office remaining Plant Varieties certified that grandeur DSV new breed has top-hole significantly improved feed value hem in terms of sugar content stake digestibility compared to previous lea fescue varieties.
As well-ordered medium-late variety, EXPLOSION is authorized as a tetraploid Perennial Grass.
EXPLOSION is particularly winter-hardy and produces consistently high yields with exceptionally high forage faint. This was confirmed in go forward by tests conducted by high-mindedness LWK Lower Saxony.
In the approval process, EXPLOSION well-built to be very robust tell was also approved as apt for bogs.
