Wang, J.K.Singh, R.P.Braun, HHPfeiffer, Wolfgang H.[Investigating the efficiency of the single backcrossing breeding strategy through computer simulation]Investigating the efficiency of the single backcrossing breeding strategy through computer simulation

Inbreeding offers numerous advantages but also presents some problems for the genetic improvement of cassava (Manihot esculenta Crantz). One of the concerns is that inbreeding depression (ID) may be too drastic for (even partially) inbred materials to survive. A large experiment was conducted to ...

Mukoko, OZGalwey, Nicholas W.Allen, David J.[Breeding beans (Phaseolus vulgaris) for BCMV resistance in Zimbabwe]Breeding beans (Phaseolus vulgaris) for BCMV resistance in Zimbabwe

A selection study was conducted with 6 hybrid bean populations in 3 double groups, with low, intermediate, and high yield potential, at CIAT`s exptl. farm in Popayan (Cauca, Colombia), in a P-deficient soil with pH 4.5. These soil conditions allow for high disease incidence such as anthracnose (C...

The objectives of the present work were threefold: first, to determine the ranges of grain and stover yields and stover quality traits in full-sib progenies of pearl millet cultivar ICMV 221; second, to assess changes in grain and stover characteristics in trait-specific experimental varieties ge...


Bidinger, F.R.Blümmel, MichaelHash, C.T.[Response to recurrent selection for stover feeding value in pearl millet variety ICMV 221]Response to recurrent selection for stover feeding value in pearl millet variety ICMV 221

Crop wild relatives, the wild progenitors and closely related cousins of cultivated plant species, are sources of valuable genetic resources for crop improvement. Persisting gaps in knowledge of taxonomy, distributions, and characterization for traits of interest constrain their expanded use in p...

This paper summarizes results from a decade of collaborative research using advanced backcross (AB) populations to a) identify quantitative trait loci (QTL) associated with improved performance in rice and to b) clone genes underlying key QTLs of interest. We demonstrate that AB-QTL analysis is c...

Agricultural research and development plays an essential role in a nation's economic development, providing for food security for an ever-increasing population. In developed countries, the gap between potential and actual yield is largely closed because of a combination of advanced technologies, ...

La yuca se cultiva por sus raíces y es el tercer cultivo fuente de calorías en el trópico. Los limitantes de la productividad incluyen constricciones bióticas y abióticas. Adicionalmente, los productores tienen problemas en el mercadeo por su rápido deterioro poscosecha y el bajo nivel de almidón...
