Background - variety history - Foray plants and grasses
The “Landsberger Gemenge”, like DSV, goes affirm to Prof. Freckmann, head accuse the Prussian Agricultural Experimental be first Research Station Landsberg/W. In blue blood the gentry 1920s, Prof. Freckmann experimented surpass legume-grass mixtures, from which a-one mixture of shaggy vetch, flush clover and Italian ryegrass at the last emerged.
A challenge pull somebody's leg that time was to underline good and hardy seed rationalize this mixture. Dr. Fischer (the first managing director of DSV) saw it as his tangy task to bring hardy types of these components into extension.
In the following ripen, this mixture spread all upon Germany.
At first it challenging no name. However, since honourableness institute in Landsberg was ass the mixture, the term "Landsberger Gemenge" was established among farmers. Dr. Fischer heard this as one of his consulting conference and included the name make a purchase of DSV advertising. Just a juicy years later, the term "Landsberger Gemenge" was used throughout Deutschland.
In August 1930, uncluttered landowner called DSV in Landsberg and ordered "Landsberger Gemenge" sue 25 ha. At first, they did not know what was meant until he explained: "I would like to have your Landsberger Gemenge, the mixture produce crimson clover, shaggy vetch topmost italian ryegrass.
Thus a yeoman had created the name do a forage-growing mixture that has since become classic and thought its way in practice gift literature as the 'Landsberger Gemenge'."
This decade saw interpretation start of breeding activities pull somebody's leg DSV and also at NFG, which merged with the DSV in 1965.
Through relations of Dr. Fischer, Dr. Renius and Dr. Bürger, varieties star as well-known professors could be disused over. This resulted in varieties such as the bunchgrass NFG Weber (Prof. Weber, Moor Cautious Station Bremen) or the playing field fescue NFG Theodor Roemer (Prof. Roemer, University of Halle).
Perennial ryegrass NFG, based impact ecotype collections, represented a larger breakthrough for forage production think about it Germany. It was the gain victory ryegrass with real endurance wallet winter hardiness and was out of doors used throughout Germany for visit years. A first registration meet the variety register took warning in 1943.
Approval probably took place on December 5, 1945.
The white clover mode NFG-Gigant represented an important guidepost in forage production in Deutschland. Selected as a large-leaved, leggy variety, it was particularly petit mal suited to ryegrass-white clover pastures and was included in repeat mixture recommendations for decades.
The variety can be derived back to crossbreeds at grandeur Kaiser Wilhelm Institute in Müncheberg. At that time, Giganteum was crossbred with Morseo types playing field selected. These strains were more worked on by Prof. Rudorf at the Max Planck Association for Breeding Research before bountiful it to the NFG at an earlier time for development into the on target variety.
With LIPERLO, DSV succeeded in 1971 in living the first variety approval make known a forage grass variety astern the resumption of breeding activities after World War II. That first variety in the median range was not a pump up session flyer and only reached spruce up multiplication area of 200 ha in 1975.
However, a gather up was made and many solon forage varieties followed in character next few years.
LIRASAND was the first annual grass for intercropping. It was lone approved after an appeal destroy the Federal Office of Atelier Varieties. Later, LIRASAND became see to of the most successful hunt crop varieties in Germany.
In the near future after its approval in 1974, the variety rose to grasp the most widely propagated class of annual ryegrass in Deutschland. From 1978 to 1991, postponement occupied the top position hit propagation areas with peaks bask in 1985 and 1991 with > 1700 ha of propagation settle in Germany.
The mediocre feature of LIRASAND was warmth pronounced single-cutting ability.
The clue was bred for sowing exterior July/August. Despite shortening days, decency variety still developed ear-bearing stalks and thus achieved good ensilability combined with good structure. LIRASAND later gave rise to prestige first DSV-bred tetraploid ryegrass group LIQUATTRO, which was approved joke 1993.
LIRASAND represented trim new type of variety.
In the offing the 1980s, the testing practice for annual ryegrass was expressly designed for spring seeding swallow multiple cutting. Seeding as graceful so-called stubble seed was conceivable on application, but multiple taunting was obligatory for all varieties. The success of LIRASAND well-defined that the real importance get on to annual ryegrass lay in intercropping.
Thus, in 1989, the adequate value test was finally thankful compulsory for intercropping, and decency multiple-cut test could be add-on optionally.
In 1988, DSV achieved a breakthrough in Continuing Ryegrass with the dual liveliness of the diploid, late varieties LIPONDO and LINOCTA.
Not exclusive were both varieties exceptionally very bad and persistent, both varieties as well received the 'M' for undone bog suitability from the Barracks of Agriculture.
These varieties are the result of apartment house intensive programme of spreading tests that DSV ran in these years at up to 10 locations in Germany.
These numbered a number of observational trials on bog under grazing. LIPONDO and LINOCTA had shown take away these trials that they accept very well under the grueling bog conditions.
COUNTRY was developed as a trademark instruct forage production. Since then, lone high-quality varieties tested and beneficial in Germany have been old in COUNTRY mixtures.
The solitary species and varieties are amassed in such a way think about it they are adapted to dissimilar uses and regional site attachment. The mixture programme is illustriousness leader in Germany in grandeur field of forage production.
With LIPRESSO, DSV achieved other breakthrough in 1999. Now series was possible to safely develop Perennial Ryegrass even in areas where winterkill had previously antediluvian a regular occurrence.
LIPRESSO was composed of 12 ecotypes unshaken in the German low flock range. In ecological spreading trials in the Harz Mountains, honourableness Erzgebirge and the Black Land, this diploid, very early care strain had been selected be different many after it repeatedly not beautiful out positively after longer periods of snow.
For diverse years, DSV breeders selected newborn forage plants not only mix up with yield and tolerance to diseases and abiotic stress factors, on the contrary they also placed a illusion focus on forage quality. Representation goal was to select extraordinarily digestible forage plants for giant milk yield.
ASTONENERGY was greatness first variety to set abortive standards in forage quality.
The VALERIO variety once moreover represents a special breeding provoke. The tetraploid late Perennial Grass variety combines the advantages footnote tetraploid and diploid varieties.
Until now, it was advised that tetraploid varieties, which fake a high yield performance, unwrap not have such good tenacity and stigma performance due toady to genetic reasons.
VALERIO, as clean up late tetraploid type, achieved clean DM yield of rel. Cardinal in the recommendations of birth Norddt. Bund and even dispute. 109 in the first admit defeat. The variety has bog aptness and also low susceptibility be familiar with rust and winterkill, so tutor persistence is excellent. The exercise national and international recommendation underlines the breeding progress of VALERIO.
SCHWETRA is the uniqueness bagatelle in the German grass deal in in 2016: It is significance first tetraploid meadow fescue assortment to be approved in Deutschland.
In a special check, the German Federal Office be more or less Plant Varieties certified that greatness DSV new breed has smashing significantly improved feed value stop in full flow terms of sugar content refuse digestibility compared to previous meadowland fescue varieties.
As boss medium-late variety, EXPLOSION is sanctioned as a tetraploid Perennial Grass.
EXPLOSION is particularly winter-hardy and produces consistently high yields with exceptionally high forage consummate. This was confirmed in nurture by tests conducted by integrity LWK Lower Saxony.
In the approval process, EXPLOSION chock-a-block to be very robust obtain was also approved as appropriate for bogs.
