Resumen
Descripción
By July 2016, e orts at CIP-Headquarters in Peru to systematically exploit
heterosis were well advanced with testing of hybrid progenies underway
following a full cycle of reciprocal recurrent selection (RRS). In Uganda,
results on the potential to exploit heterosis con rm selecting strongly for
virus resistance using RRS. Genetic gains of 0.3 t/ha/year in storage root
yield of released varieties over the years were found across programs in
Ghana, Mozambique and Peru. Two improved data collection, storage and
analysis tools were introduced to the breeding community of practice:
Highly Interactive Data Analysis and Productivity Tools for Breeding
(HIDAP) and Sweetpotatobase.
