The Evaluation On Crossabilities Of Chinese Wheat Landraces, M. C. Luo, C. Yen, J. L. Yang, Z. L. Yang

Herbarium Publications

The total of 865 accessions of Chinese bread wheat landraces (Triticum aestivum L.) has been investigated on their crossabilities with rye (Secale cereale L.), of which 121 land races showed similar crossability to Chinese Spring, 50 accessions had much higher crossability than Chinese Spring, and 693 varieties were non-crossable with rye or had lower crossability than Chinese Spring. The analysis on the geographical distribution indicated that the landraces with high crossability occurred in most parts of China. Some utilization of high crossability resources was also discussed.

Breeding Potential Of Exotic Barley Germplasm, Merja Veteläinen

Herbarium Publications

Utilization of exotic germplasm offers an approach to broaden genetic variability in breeding populations. This study was conducted in order to 1) compare germplasm of exotic origin with adapted Swedish barleys with respect to genetic differences and 2) to evaluate first cycles of pre-breeding i.e. agronomic traits in complex exotic x adapted crosses. Allozyme studies showed the following Nei's gene diversities among parents: 0.13 (adapted parents), 0.16 (landraces) and 0.25 (H. spontaneum). Cluster analysis based both on allozyme and agronomic data indicated that parental groups were genetically divergent. Earliness, straw length, number of ears per plant and thousand …

Prospects For Gene Lntrogression From Hordeum Bulbosum L. Into Barley (H. Vulgare L.)., R. A. Pickering, A. M. Hill, G. M. Timmerman-Vaughan, E. M. Forbes, M. G. Cromey, M. J. Gilpin, M. Michel, M. Scholz

Herbarium Publications

Hybridizations between Hordeum vulgare L. (cultivated barley) and H. bulbosum L. have been performed over many years with two aims. First, the production of doubled haploid barley cultivars (Kasha and Kao 1970); second, the transfer of desirable traits such as resistance to fungal and viral pathogens from the wild species into barley. Apart from the report of an occasional recombinant (Xu and Kasha 1992; Pickering et al 1994), successful gene introgression has been hampered by several barriers. In this report we will describe recent progress in overcoming these barriers.

Progress In Polyhaploid Production Techniques Of Hexaploid Wheat Through Wide Crosses, M. N. Inagaki, A. Mujeeb-Kazi

Herbarium Publications

(Triticum aestivum L.) through wide crosses were evaluated in terms of pollen sources, 2,4-D application, embryo rescue and chromosome retention. Pollen sources included Hordeum bulbosum L., Zea mays L., Pennisetum glaucum (L.) R. Br., Sorghum bicolor (L.) Moench, and Tripsacum dactyloides (L.) L. Maize-mediated polyhaploid production was more stable than the other methods because of a lesser genotypic influence on embryo formation. Application of 2,4-D onto wheat after pollination was critical to promote seed setting and embryo formation in all cross combinations. Embryo rescue was necessary at an appropriate embryo developmental stage to obtain plant regeneration. Paternal chromosomes were …

Plant Germplasm Resources, S. A. Eberhart, H. E. Bockelman

Herbarium Publications

Landraces and wild relatives of crops from centers of diversity have been rich sources of resistance to new pathogens, insect pests, and other stresses as well as for traits to improve food and fiber quality, animal feed, and industrial products. Because very few crops grown in the U.S. are native, plant introductions are vital to our agriculture. The National Plant Germplasm System (NPGS) was established to acquire, preserve, and distribute plant genetic resources from around the world so that scientists have immediate access to these source materials. The active collection is maintained and distributed by 19 national germplasm repositories. The …

Perennial Lymegrass (Leymus Arenarius And L. Mollis) As Potential Crop Species For Northern Latitudes, Kesara Anamthawat-Jónsson, Jón Gudmundsson, Birkir Bragason, P. K. Martin, R. M. D. Koebner

Herbarium Publications

The aim of the present study is to improve the perennial lymegrass (L. arenarius and L. mollis) for cultivation as potential cereal crop for Iceland as well as for other regions of native lymegrass distribution. The study will also provide cereal breeders with broader genetic resource containing several characters of the wild species such as tolerance to extreme environments and perhaps resistance to pathological diseases.

Nebraska Farm Real Estate Market Developments 1993-94, Bruce Johnson

Nebraska Farm Real Estate Reports

Agricultural land values rose across the state during 1993, averaging 6.6 percent for the year ending February 1, 1994. According to the 1994 Nebraska Farm Real Estate Market survey, largest annual increases were reported in the east, southwest, and north areas with percentage increases of 8.9 percent, 8.4 percent, and 8:0 percent respectively.

While weather adversity was widespread across Nebraska during 1993, buyer interest remained keen, and appeared to intensify in late 1993 and early 1994 as crop commodity prices rose.

In any local market, agricultural land values will exhibit rather pronounced ranges in market values depending upon real and …
