Selection for some types of resistances significantly influenced the level of resistance to other traits. Risk of Pollen Migration in Transgenic Alfalfa. TAGS: Dairy. These structural analyses have been employed in assessing alfalfa forage characteristics, allowing for rapid, convenient and cost-effective analysis of alfalfa forage quality. Complete male sterility and complete male fertility were stable traits. Three promising combinations have been found. The improved germplasms will be tested for their potential in nitrate remediation of soils and ground water. One type of resistance was controlled by one dominant gene, the other type of resistance was controlled by two additive genes. Anthracnose in alfalfa plants, caused by Colletotrichum trifolii, is one of the most serious diseases affecting alfalfa and results in stem death, crown rot, and reduced winter survival. alfalfa. This allows flexibility to harvest at the regular interval and get very high quality forage or delay harvest to increase yield and get similar quality as a conventional alfalfa at an earlier growth stage. Resistant lines selected in 1969 were evaluated for forage and root yield in the field under frequent irrigation on soil previously infested with P. megasperma. Traits that were measured included: number of seeds/pod, seed size, seedling vigor, secondary and fibrous root scores, crown and root weight, seeding year forage yield, and fall growth score. Alfalfa Operations. Vogel, K.P. To improve forage quality in alfalfa, the three cycle of selection were conducted to create alfalfa populations that differ in stem fiber digestibility. This suggests that the environment interacts with genetics to affect performance. 79-98. In a biomass energy production system the leaves are separated from the stems and sold as a high quality Significant differences were observed among the germplasm sources. Following freezing, the plants were thawed for 12 hours at 4(degree) C and then planted in greenhouse in press. Three unrelated germplasms were grown under N(2) dependent growth conditions. Samac.

Five alfalfa breeding companies are collaborating by increasing seed of the historical varieties. Pollen-tube length was measured for OP, S(l), single cross (SC), Syn 2 (S(l) for single cross plants), F(2) and double cross (DC) progenies from nine germplasm sources. A study was initiated comparing the forage quality of these biomass germplasms to commercially available hay type alfalfa. Marketing. Realized heritability for high shoot weight was greater when selected in combination with high shoot N concentration than when selected with low shoot N concentration (H= 0.59 vs. 0.28). Two Phytophthora resistant germplasm releases, MnP-Bl and MnP-Dl, were officially released to alfalfa breeders. The inserted gene produced the same protein as found in other roundup ready crops on the market. Crop Sci. Crop Sci. Yield improvement in alfalfa is even more costly and time consuming because selection for yield requires field trials over many years and locations, involves many different genes, and environmental effects slow genetic gain. This was developed through the insertion of a gene owned by Monsanto Company that confers resistance to glyphosate, a broad-spectrum herbicide, also known as Roundup. 1999. We develop cutting-edge trait technologies that deliver top-notch performance and results. The best population (MN-SWXUC) was increased and retested at four diverse Minnesota locations in 1984.

Results suggest genetic potential for increased manure tolerance in alfalfa and a second and final cycle of selection for improved tolerance has been initiated. The complex nature of the trait makes it difficult to evaluate and to predict. Alfalfa in combination Crown morphology relationhships among alfalfa plant introductions and cultivars. A study to test the hypothesis that self-seed set is a quantitative character has been started. This “Queen of Forages” is the mainstay for forage production in Montana. Studies on the genetics of self-incompatibility are being continued. Forage Genetics is followed by less than 10 members. Selected populations and crosses between the germplasm sources are evaluated with 1 5N to determine N(2)-fixation under field conditions. Some information was revealed by both types of analyses while other information was revealed by only one type of analysis. Alfalfa (Medicago sativa L.) is a perennial legume widely cultivated to provide high-quality forage in the form of hay, silage, and to a lesser extent as a grazing crop, as well as for improving soil fertility. FGI and Alforex are pleased to announce that the litigation has been resolved. The non-nod trait was conditioned by two tetrasomically inherited recessive genes (nn(1) and nn(2)). Li (Horticulture).Impacts(N/A)Publications, Progress 01/01/90 to 12/30/90OutputsThe U.S. collection of alfalfa plant introductions includes about 2500 perennialaccessions. I want to discuss some research we are pursuing to use genetic markers to improve yield (and other traits). A selection program is in progress to determine how these factors are associated with N(2) fixation and if it is possible to breed a high N(2)-fixing cultivar. We also found that large plants were more likely to recover from freezing than small plants in the same entry. 41:403-416. Moore and M. Collins (ed.) Recent studies have shown that ineffectively nodulated alfalfa takes up 38% more soil nitrate-N than normal This two cut biomass production system will delay spring harvest which will promote improved nesting habitat for wildlife as well as be more profitable for growers. Progeny evaluations of inbred materials as male parents suggest that thefrequency of maintainer genes differs drastically among S(1) families. Crop Sci. Ten alfalfa cultivars were seeded at Rosemount, MN in rows in early June of 1991. All of these varieties are adapted to irrigated and dryland acres. Orange-root color caused by poly-lycopene was controlled by a recessive gene (or) with tetrasomic inheritance. 2001. Very high yield potential under 3- to 5-cut harvest managements. In a biomass energy production system the leaves are separated from the stems and sold as a high quality animal feed, while the stems are processed to produce biofuels or electricity.

The Non Dormant Alfalfa Seed . The third cycle of selection for alfalfa populations with improved stem and leaf yield for use in biomass energy production system has been completed. In conventional plants, glyphosate binds to an enzyme, blocking the biosynthesis of aromatic amino acids and depriving the plant of essential components (Haslam, 1993; Steinrucken and Amrheim, 1980). To improve forage quality in alfalfa, the first cycle of selection has been completed to create alfalfa populations that differ in stem fiber digestibility. Two important nodule enzymes involved in N assimilation are glutamate synthase (GOGAT) and phosphoenolpyruvate carboxylase (PEPC). Experiments were conducted during both 1992 and 1993 at Rosemount and Becker, MN to determine the influence of determinate (Sava) and indeterminate (Kelson), Medicago scutellata varieties, on the growth of corn and MN-SWXUC produced an additional 17% (10 lb/A) more than the unselected nondormant checks. We have increased the N(2) fixation rate of alfalfa by breeding, however, this generally has not resulted in increased yields. Five varieties were sampled weekly for insects,diseases, plant growth and forage quality. Plants were washed, clipped at 5 cm above the crown and 10 cm below the crown, bundled into groups of five, and stored at -2 (degree)C. One bundle of each entry was packaged into a 12x6x6 cm cardboard box containing 10 cm of dry vermiculite. Proc. 2000. Central Alfalfa Improv.
