Selection for drought tolerance increases maize yields across a range of nitrogen levels
It is not known whether selection for improved tolerance to a specific abiotic stress leads to correlated changes in performance under other stresses. Drought and N deficiency are important constraints to production in the ...
Efficiency of high-nitrogen selection environments for improving maize for low-nitrogen target environments
Most maize (Zea mays L.) in the tropics is grown under low-nitrogen (N) conditions, raising the need to assess efficient breeding strategies for such conditions. This study assesses the value of low-N vs. high-N selection ...
Inbred line evaluation nurseries and their role in maize breeding at CIMMYT
(Consiglio per la Ricerca e la sperimentazione in Agricoltura, Unità di Ricerca per la Valorizzazione qualitativa dei cereali, 1999)
CIMMYT initiated its hybrid maize (Zea mays) research programme in 1985 in response to the growing needs of the national programmes for hybrid-oriented source germplasm. Since 1991 CIMMYT has released a total of 424 inbreds ...
Heterotic patterns of ninety-two white tropical CIMMYT maize lines
(Consiglio per la Ricerca e la sperimentazione in Agricoltura, Unità di Ricerca per la Valorizzazione qualitativa dei cereali, 1992)
Development of inbread-based populations which are heterotic to each other was considered one of the primary goals when CIMMYT started of this study were to determine the combining ability and heterotica patters of tropical ...
Inheritance of resistance to southern corn rust in tropical-by-corn-belt maize populations
(Springer Verlag, 1998)
The inheritance of resistance to southern rust (caused by Puccinia polysora Underw.) was investigated in two F2:3 populations derived from crossing two temperate-adapted, 100% tropical maize (Zea mays L.) inbred lines ...
Wheat breeders' perspectives on genetic diversity and germplasm use: Findings from an international survey
Wheat breeders working in national wheat research programmes around the world, and particularly those in developing countries, are concerned that in the future scientific advance may be limited because wheat genetic diversity ...
