Centa Ss- 44, New Sorghum Forage Hybrid For El Salvador, Intsormil

INTSORMIL Impacts and Bulletins

One of the major problems plaguing the development of the Central American dairy industry is the lack of good quality forage which results in low milk and meat production and an increase in production costs. Many dairy farmers, in their search for suitable forage to feed their cattle herds, utilize poor quality sorghum or maize hybrids which can result in economic losses.

In the case of sorghum, the major problem is a lack of cultivars that (1) are early, (2) grow rapidly, (3) are of proper plant height, (4) are resistant to diseases, (5) have high yield potential and (6) …

Sorghum: A Substitute For Maize In The West Africa Poultry Industry, Intsormil

INTSORMIL Impacts and Bulletins

With the declining relative prices of chicken compared with other meats, poultry consumption per capita in the USA has been increasing, while that of other meats has been stagnant or declining. Similar developments are occurring in West Africa.

There is interest in substituting sorghum for maize in poultry rations, in the U.S. and in West Africa, for both broiler and egg production. In contrast to maize, which is a thirsty plant and requires large amounts of water, sorghum offers farmers the ability to grow a crop where other crops do not produce well.

Fertility Restoration Of The Sorghum A3 Male-Sterile Cytoplasm Through A Sporophytic Mechanism Derived From Sudangrass, Hoang V. Tang, Jeffrey F. Pedersen, Christine D. Chase, Daryl R. Pring

Department of Agronomy and Horticulture: Faculty Publications

Fertility restoration of sorghum [Sorghum bicolor (L.) Moench] lines carrying the IS1112C (A3 group) male-sterile cytoplasm has been documented as a two-gene gametophytic mechanism involving complementary action of restoring alleles designated Rf3 and Rf4, as derived from IS1112C. Fertility restoration capability has also been reported from sudangrass (S. bicolor subsp. drummondii) populations. We describe characteristics of a fertility restoration system derived from sudangrass, in which male-sterile individuals were observed at high frequency in backcross and F₂-F₃ segregating populations. Segregation analyses were consistent with a sporophytic restoration system involving two complementary genes. Pollen iodine …

Nutrient Use Efficiency: Measurement And Management, Achim Dobermann

Department of Agronomy and Horticulture: Faculty Publications

Mineral fertilizers have sustained world agriculture and thus global population and wealth growth for more than 100 years (Smil, 2001; Stewart et al., 2005). Their contribution to increasing crop yields has spared millions of hectares of natural ecosystems that otherwise would have been converted to agriculture (Balmford et al., 2005). However, lacking, imbalanced, inappropriate or excessive use of nutrients in agricultural systems remains a concern. Nutrient mining is a major cause for low crop yields in parts of the developing world, particularly Africa. In other situations, nutrients such as nitrogen (N) and phosphorus (P) often move beyond the bounds of …

Map Location Of The Rpp1 Locus That Confers Resistance To Soybean Rust In Soybean, D. L. Hyten, G. L. Hartman, R. L. Nelson, R. D. Frederick, V. C. Concibido, J. M. Narvel, P. B. Cregan

Department of Agronomy and Horticulture: Faculty Publications

Soybean rust (SBR), caused by Phakopsora pachyrhizi, was first discovered in North America in 2004 and has the potential to become a major soybean [Glycine max (L.) Merr.] disease in the USA. Currently, four SBR resistance genes have been identifi ed but not mapped on the soybean genetic linkage map. One of these resistance genes is the Rpp1 gene, which is present in the soybean accession PI 200492. The availability of molecular markers associated with Rpp1 will permit marker-assisted selection and expedite the incorporation of this gene into U.S. cultivars. We compared simple sequence repeat (SSR) markers between …
