Phenotypic Data

Common bean (Phaseolus vulgaris L.) is a major component of agricultural systems and diets of the urban and rural populations of East and Central Africa, providing Fe and Zn essential to the health and well-being of African women and children, and protein essential for the entire household. However, bean consumption is limited by constraints such as long cooking time (CT). Cooking demands large amounts of water, fuel and time. It has negative effects on the environment, livelihoods, security and health. Genetic variability in cooking time is documented. Recent development of new breeding methods based on pedigree and genomic selection together with optimal contribution selection (OCS) offers an opportunity to accelerate breeding for rapid CT and higher Fe and Zn grain content. Genotypic and phenotypic data of an African diversity pool, representing key bean market classes, were used to generate genomic estimated breeding values (GEBVs) for grain yield, CT, Fe and Zn. GEBV’s were weighted to maximise the desired outcome in an economic index. From 161 candidate bean genotypes with GEBVs, 67 were chosen for 80 matings within six major grain market classes. An additional 22 breeder nominated matings were included. The predicted outcomes in the first cycle showed a major improvement in population mean for index (+286.77 US$/ha), 6.2% increase in GY and 7.3% reduction in CT, with an achieved increase in population co-ancestry of 0.0753. A 30% reduction in the mean population CT and improved Fe (15%) and Zn (10%), is expected after 5 cycles of annual recurrent selection.

Hooked trichomes on common bean (Phaseolus vulgaris L.) plants are known to function as a plant defence against phytophagous insects and rust disease, and wide genotypic variability exists for trichome density. A bean cross between small-leafed, low-trichome-density cv. Harokent (P1) and broad-leafed, high-trichome-density cv. California Dark Red Kidney (P2) was analyzed to determine the inheritance of leaf area and trichome density of the first trifoliolate leaf under controlled environments. The F1 hybrids had leaf areas similar to those of the broad-leafed parent P2, had a trichome density similar to that of P1, and had fewer trichomes per leaf than the mid-parental value. Frequency distribution of the characteristics for the F2 and backcross P1F1 were skewed toward P1 but displayed continuous variation, with means around the mid-parental values. Generation-means analysis suggested control of the characteristics by additive, dominance and epistatic gene interactions. Low narrow-sense heritability estimates were obtained for these characteristics. Significant correlations between leaf area and trichome abundance and between trichome abundance and density were obtained, but leaf area and trichome density were not correlated. Selecting small leaves with high trichome density may be accomplished, since they are independent. These two characteristics are desired in small white pea bean cultivars. However, several cycles of recurrent selection in large populations may be required to combine these two desired characteristics.
