Indicators of wheat genetic diversity and germplasm use in the People's Republic of China
A preliminary study of wheat genetic diversity in the People's Republic of China is presented. Available evidence and basic data related to the ancestry of leading wheat cultivars and the area distribution of dominant ...
Breeder demand for and utilisation of wheat genetic resources in Australia
As part of an ACIAR-funded project on genetic diversity in wheat in Australia and China, Australian wheat breeders were surveyed to assess the importance of genetic diversity to breeders. This paper reports the findings ...
The contribution of genetic resources and diversity to wheat productivity: A case from the Punjab of Pakistan
This study makes use of data on wheat production in the Punjab of Pakistan from 1979 to 1985 to 1) examine patterns of varietal diversity in farmers' fields both at the regional and district levels and 2) identify how and ...
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 ...
Transgenic technology: Pro-poor or pro-rich?
Transgenic crops were originally developed for temperate climates and industrialized agriculture. Nonetheless, genetic engineering has the potential to address some of the most challenging biotic and abiotic constraints ...
Institutional change and discontinuities in farmers' use of hybrid maize seed and fertilizer in Malawi: Findings from the 1996-97 CIMMYT/MoLD Survey
This study records the use of hybrid maize seed and fertilizer by small-scale farmers in Malawi, as well as their opinions about these inputs, from 1989-90 through 1996-97. Its main purpose is to determine whether the ...
