HERITABILITY, COMBINING ABILITY AND INHERITANCE OF STORAGE ROOT DRY MATTER IN YAM BEANS
Storage root dry matter content (RDM) is central to the improvement of consumer and industrial attributes of root crops. Yam bean ( Pachyrhizus species) is a legume root crop newly introduced in Uganda, but its adoption may be constrained by low RDM. The objective of this study was to investigate th...

Zusammenfassung: | Storage root dry matter content (RDM) is central to the improvement of
consumer and industrial attributes of root crops. Yam bean (
Pachyrhizus species) is a legume root crop newly introduced in
Uganda, but its adoption may be constrained by low RDM. The objective
of this study was to investigate the magnitude of variance for general
combining ability (GCA) and specific combining ability (SCA) effects,
heritability estimates and inheritance of RDM in yam beans. Progenies
of sixteen crosses, generated using the North Carolina (NCII) mating
scheme, were evaluated in F1 and F2 field experiments, with three
replications at the National Crops Resources Research Institute
(NaCRRI), Namulonge in Central Uganda, during the first cropping
seasons of April, 2013 and 2014, respectively. Significant (p |
