In India cassava breeding is done mainly at the Central Tuber Crops Research Institute (CTCRI) in Trivandrum, as well as in the State Agricultural Universities through the All India Co-ordinating Centres. CTCRI maintains 786 exotic and 848 indigenous accessions of cassava and 8 wild species in it...

The report covers varietal improvement for the period 1990-1993. Not much progress was made in the 1990/91 season due to the occurence of a super typhoon that damaged standing field trials. In recent years, however, progress in selection was made in terms of high yield and dry matter content and ...

As research on food crops intensifies in the tropics, the spotlight is being increasingly focused on the development of varieties with resistance to pests and diseases. Much of the time, money and patience needed to conduct research on host plant resistance (HpR) is spent on the development of me...

Crop wild relatives native to the United States have proved useful as genetic resources in breeding more productive, nutritious, and resilient crops. Their utilization is expected to increase with better information about the species and improving breeding tools. But this utilization may be const...

Multilocation evaluation trials (MET) constitute an important step in the evaluation of breeding lines, in order to assess their adaptation and stability patterns across environments, and to ensure optimal targeting of the lines. Seven Musa genotypes comprising five plantain hybrids, one cooking ...

Water stress is one of the major abiotic stress limitations for grain legume production in smallholder agricultural systems. Phenotypic characterization of water consumption by different species of legumes and genotypes within them plays a key role in adaptation to drought. Dynamics of water use ...

Several primary tetraploids with desirable attributes have been selected by Musa breeding programs. Diploid parental stocks have become available for further genetic improvement of the Musa genome. Hence, new genome manipulations should be tested before they become routine in breeding programs. T...
