Instructions for the management and reporting of results for the CIMMYT Wheat Program International Nurseries
Over the last two decades, CIMMYT's international multilocation testing of experimental germplasm has become widely accepted as a viable approach to accelerating the germplasm improvement process. Given the diversity of ...
A predetermined proportional gains eigen selection index method
The most general linear phenotypic selection index (PSI) is the predetermined proportional gains phenotypic selection index (PPG-PSI) that allows imposing restrictions on the trait expected genetic gain values to make some ...
Photosynthetic contribution of the ear to grain filling in wheat : a comparison of different methodologies for evaluation
(Oxford University Press, 2016)
The culm (particularly the flag leaf) and the ear are believed to play a major role in providing assimilates for grain filling in wheat. However, the results obtained in the past varied depending on the methodology applied. ...
Bio-energy, water-use efficiency and economics of maize-wheat-mungbean system under precision-conservation agriculture in semi-arid agro-ecosystem
The maize-wheat-mungbean (MWMb) cropping system is being advocated as an alternative to the traditional rice-based cropping systems of north-western Indo-Gangetic Plains (IGP) to address the issues of energy and nutritional ...
