Research And Development Strategies For A Sustainable Agriculture, Charles A. Francis

"Food production and rural income are two prime concerns of Third World governments. Increased food production and greater food security are goals which countries strive to achieve through agricultural development. The technologies generated by research, commonly known as green revolution methods, have provided an impetus to food production in some favored zones where resources are available to take advantage of this production package. New varieties, productive and responsive to fertilizer, have bought time while countries work to control population growth and develop agriculture and industry" (Francis and Harwood, 1985).
The pioneering work of the International Agricultural Research Centers has been …
Combining Ability Effects For Mineral Elements In Forage Sorghum Hybrids, H. J. Gorz, Francis A. Haskins, Jeffrey F. Pedersen, W. M. Ross
Combining Ability Effects For Mineral Elements In Forage Sorghum Hybrids, H. J. Gorz, Francis A. Haskins, Jeffrey F. Pedersen, W. M. Ross

The concentrations of minerals in forages are important in satisfying animal requirements, but little attention has been given to determining these concentrations in forage sorghum (Sorghum bicolor (L.) Moench.) breeding programs. In this 2-yr study, the objectives were to determine the contents, genetic variability, combining ability effects, and correlations for 12 mineral elements in 49 experimental hybrids of forage sorghum. Mineral elements studied were N, Mg, Si, P, S, CI, K, Ca, Mn, Fe, Cu, and Zn. General combining ability (GCA) effects exceeded specific combining ability (SCA) effects for all elements except P, CI, and Fe in females, and …
Inheritance Of Seedling Hydrocyanic Acid Potential And Seed Weight In Sorghum-Sudangrass Crosses, J. F. S. Lamb, Francis A. Haskins, H. J. Gorz, Kenneth P. Vogel
Inheritance Of Seedling Hydrocyanic Acid Potential And Seed Weight In Sorghum-Sudangrass Crosses, J. F. S. Lamb, Francis A. Haskins, H. J. Gorz, Kenneth P. Vogel

The hydrocyanic acid potential (HCN-p) of sorghum (Sorghum Bicolor (L.) Moench] plants is recognized as a heritable trait, but previous studies on the mode of inheritance of HCN-p have produced inconsistent results. The objective of this study was to investigate the inheritance patterns of seedling HCN-p and also of seed weight in reciprocal crosses of sorghum and sudangrass (formerly S. sudanense (Piper) Stapf). Both traits were found to be inherited quantitatively. Generation means analysis indicated that additive genetic effects were most important for both seed weight (53% of variation) and seedling HCN-p (74% of variation). A maternal effect was …
