Greenhouse screening for Fusarium wilt resistance in lupine
Fusarium wilt can cause total crop failure. Evaluation of Ffusarium resistance in heavily infected soil were performed in a grenhouse where the dominant fusarium species in the soil in descending order was F. oxysporum then F. avenaceum, F. culmorum, F. solani, F. gibbosum. Large fusarium wilt presure was observed and fully susceptible lines were completely destroyed by Fusarium wilt caused by F. oxisporum. Segregation in F2 and F3 in L. angustifolius showed that resistant genotypes have two dominant non-allelic resistance genes to wilt. We call this gene Relation to fusarium oxisporum (Rfo1,Rfo2). Susceptible genotypes have either two wild genes (++ ++) or one wild and one dominant resistant gene (++ Rfo2 Rfo2, or Rfo1Rfo1 ++). Crossing ‘++ Rfo2Rfo2’ to ‘Rfo1Rfo1 ++’ segregates in 9:7 resistant to susceptible in F2, respectively. The same segregation was observed by crossing ‘Rfo1Rfo1 Rfo2Rfo2’ to ‘++ ++’. We recommend the use of these resistant genes in breeding in areas with potential Fusarium wilt problems
Adaptation of lupins for Northern European maritime conditions
Lupin as a grain crop has been restricted in growing area to more continental conditions due to their indeterminate growth form, which in maritime Northern European areas causes excessive vegetative development, late and uneven ripening and lodging. However, new reduced branching types provides better possibilities for adaptation to these conditions, and preliminary results indicates potential seed yields up to 5-6 tons per ha in the narrowed leafed lupins (Lupinus angustifolius) and an acceptable stable and early ripening. Due to full susceptibility to anthracnose (Colletotrichum gloeosporioides) in white (L. albus) and yellow (L. luteus) their introduction in these environments is doubtful. In these growing areas Botrytis (Botrytis cinerea) and fusarium (Fusarium avenaceum and F. oxispurum) appear to be the most important diseases for narrowed leafed lupins. As the narrowed leafed lupins is a young crop in modern breeding significant progress in adaptation to northern European conditions, in yield potential, quality and disease resistance is expected
Choise of species and varieties for grain legumesand cereals for inter- and monocropping in organic agricultural systems
Short stem peas and early ripening narrow leaved lupins with restricted branched are the best option for inter-cropping with spring barley and - wheat, with respect to synchronized development and stand ability. Traditional branched lupins and faba beans outgrew and ripened much later than the inter-cropped cereals. Weed infestations decreased slightly in the mixtures with barley compared to the cereal mono-culture and several times compared to the legume mono-cultures

Male breast cancer: a nation-wide population-based comparison with female breast cancer
<p><b>Objective:</b> Describe prognostic parameters of Danish male breast cancer patients (MBCP) diagnosed from 1980–2009. Determine all-cause mortality compared to the general male population and analyze survival/mortality compared with Danish female breast cancer patients (FBCP) in the same period.</p> <p><b>Material and methods:</b> The MBCP cohort was defined from three national registers. Data was extracted from medical journals. Data for FBCP is from the DBCG database. Overall survival (OS) was quantified by Kaplan–Meier estimates. Standardized mortality ratios (SMRs) were calculated based on mortality rate among patients relative to the mortality rate in the general population. The association between SMR and risk factors were analyzed in univariate and multivariable Poisson regression models. Separate models for each gender were used for the analyses.</p> <p><b>Results:</b> We found a marked difference in OS for the two genders. For the total population of MBCP, 5- and 10-year survivals were 55.1% and 31.7%, respectively. For FBCP, the corresponding figures were 76.8% and 59.3%. Median age at diagnosis for FBCP was 61 years and 70 years for MBCP. By applying SMR, the difference in mortality between genders equalized and showed pronounced age-dependency. For males <40 years, SMR was 9.43 and for females 19.56 compared to SMR for males 80 + years (0.95) and females 80 + years (0.89). During the period 1980–2009, the risk of dying gradually decreased for FBCP (<i>p</i> < .0001). The risk 1980–1984 was 35% higher than 2005–2009 (RR 1.35). Although the risk of dying for MBCP was also lowest in 2005–2009, there was no clear tendency (<i>p</i> = .1439). The risk was highest in 1990–1994 (RR =2.48).</p> <p><b>Conclusion:</b> We found better OS for FBCP than for MBCP. But SMR showed similar mortality rate for the two genders, except for very young FBCP, who had higher SMR. Furthermore, significantly improved survival over time for FBCP was observed, with no clear tendency for MBCP.</p
