Genetic Gains by Region Published in SASHA II Final Report
The 5-year (July 2014–October 2019) Sweetpotato Action for Security and Health in Africa Phase 2 project (SASHA2) has succeeded in almost all its objectives centered on resolving the major bottlenecks for fully exploiting ...
OFSP Hybrid 1 Population for Wide Adaptation & Earliness
The strategy for exploiting heterosis in sweetpotato breeding was validated in 3 distinct populations in Peru and in Uganda and Mozambique.
Selection of parents in a population hybrid breeding scheme for sweetpotato in Uganda
In Uganda, 40 parents were selected (20 for each parental group) on the basis of BVs combined by a modified Pesek-Baker index using standardized desired genetic gains and other information such as flesh color.
Responses to selection & breeding efficiencies determined by model calculations in the accelerated breeding scheme (ABS) for 1 year and 2 year testing in early breeding stages on basis of variance components estimated in the controlled cross versus poly-cross breeding experiment
The variance components estimations in early breeding stages for this deliverable are available on basis of 3x 1000 clones, two years, two locations and two plot replications – no clones were discarded in this experimental ...
