Las investigaciones relacionadas con el triticale (X. Triticosecale Wittmack), el producto de un cruzamiento entre el trigo y el centeno, en realidad comenzaron en el CIMMYT un año antes de que se estableciera formalmente ...
Utilizing wild grass biodiversity in wheat improvement: 15 years of wide cross research at CIMMYT
For the first time, this report brings together detailed accounts of new knowledge and techniques developed through wheat wide crosses research at CIMMYT since this work was initiated in 1979. Beginning with a summary of ...
Economic criteria for establishing plant breeding programs
A general model of annual costs and lagged annual returns from a plant breeding program is developed to estimate the threshold sizes of a crop industry at which different breeding programs could be economically justified, ...
Impacts of international wheat breeding research in the developing world, 1966-90
1986-90. Overall, varieties originating directly from CIMMYT crosses or from NARS crosses using a CIMMYT parent occupy 40 million hectares of wheat in the developing world. It is estimated that adoption of MVs from 1977 ...
Estimating the economic impact of breeding nonspecific resistance to leaf rust in modern bread wheat
(American Phytopathological Society (APS), 1998)
Breeding for resistance to rust diseases in wheat is an example of productivity maintenance research. Productivity maintenance research is necessary to avoid contractions in the wheat supply curve that result from changes ...
Optimal search in ex situ collections of wheat genetic resources
This paper develops a theoretical model for analyzing gene bank management decisions regarding the search for traits of economic value in ex situ collections of wheat. The model is applied to data on the probability of ...
CIMMYT Report on wheat improvement 1973
The year 1973 marked the 28th year of continuous research on wheat and other small grains in Mexico by CIMMYT and its predecessors. It also marked the ninth year of CIMMYT's activities as an international center, based in ...
Use of IPM in the control of multiple diseases in maize: strategies for selection of host resistance
(African Crop Science Society, 2003)
Maize (Zea mays) production in sub-Saharan Africa is constantly threatened by the potential outbreak of multiple foliar diseases such as maize streak, northern leaf blight, gray leaf spot, and rust. Improvement of host ...
Breeding and genetic estimation of spring bread wheat populations of the Siberian shuttle breeding nursery of CIMMYT
(Institute of Cytology and Genetics of Siberian Branch of the Russian Academy of Sciences, 2012)
Shuttle breeding contributes much to the breeding to common wheatvarieties resistantto adverse environmental factors by involving new sources of valuable biological and economical features from the world?s gene pool. ...
A general Bayesian estimation method of linear-bilinear models applied to plant breeding trials with genotype × environment interaction
(Springer Verlag; American Statistical Association; International Biometrics Society, 2012)
Statistical analyses of two-way tables with interaction arise in many different fields of research. This study proposes the von Mises-Fisher distribution as a prior on the set of orthogonal matrices in a linear-bilinear ...
