“…For instance, total fiber concentration varied from 1.2% to 25.6% and cellulose content ranged from 1.1% to 13.7% in Bengal gram beans Tovar and Melito (1996) Values are reported in g/100 g on a dry weight basis. These beneficial effects may include, but are not limited to, an increase in fecal bulk and fecal moisture, reduction of plasma cholesterol level, improved GI, and reduced risk of colon cancer (Nwokolo, 1996). (Salunkhe et al, 1985).…”

“…Legume seeds contain significant levels of water soluble carbohydrates, including trace amounts of monosaccharides, such as glucose and arabinose in soybeans, and measurable concentrations of disaccharides and oligosaccharides, often including sucrose, raffinose, stachyose, verbascose, and ajugose (Sathe et al, 1984;Nwokolo, 1996). Food legume seeds differ significantly in their total soluble sugar content and composition (Table 1.16).…”

African yam bean (AYB, Sphenostylis stenocarpa Hochst. ex A. Rich.) Harms is a tuber and seed crop, rich in protein, with the potential to contribute to food security. To date, available information on the diversity of AYB is scarce. This study aims at understanding the genetic diversity of 79 AYB accessions of various origins. Twenty-four morphological and taxonomic features of high descriptive values were used and the diversity within the germplasm was assessed by clustering analysis. The 79 accessions differed significantly, with the similarity distances spanning from 0.0646 to 0.5720 and a mean distance of 0.2820. The accessions were grouped into five clusters of 10-26 members. Of the 24 phenotypic variables analyzed, variegation in testa color was the most discriminatory trait, classifying the accessions in the proportion of 25% with variegated to 75% with non-variegated seeds. The ranking by significance (P B 0.05) of the ordinal variables of discriminating importance were in the order of pattern of testa variegation, basal color of variegated seeds, and testa basal color. The stepwise discriminant and frequency procedures in SAS identified other phenotypic variables with significant discriminatory attributes, such as pigmentation of plant parts, seed cavity ridges, and pod dehiscence. Accessions with desirable agronomic traits, such as longer pod length, high number of seeds/pod, non-shattering characteristics of pods at maturity, lower number of days to flowering, and a higher seed set percentage, were also identified in this study. These discriminatory traits are discussed and proposed for germplasm conservation and use.

“…are some of the ethnic groups which place significant cultural values for the crop (Potter and Doyle, 1992). Many lives were sustained during the Nigerian civil war as the crop provided the major protein source in the Igbo (Nigeria) refugee camps between 1964 to 1967 (Nwokolo, 1996). The production of the crop is remote and limited to few cultural niche where it is grown in mixed and as a companion crop with some primary crops especially yam (Dioscorea spp.).…”

The present investigation aimed at understanding the floral morphology and maturation indices of African yam bean (AYB), knowledge of which is very relevant for the crop's improvement programs. Ten accessions of AYB were grown in rows of ten plants, in three replications. Thirty anthesized flowers were collected from each accession for the study of the floral parts. The progressive development of flowers from buds was additionally investigated. AYB flower is large and complete. The calyx was fused and the corolla has five petals (one standard, two wings and two keels). AYB accessions exhibited racemes and indeterminate form of inflorescence. The mean standard petal length and width were 2.94 cm and 3.59 cm respectively. The androecium which surrounded the carpel consists of ten filaments (nine fused, one free). The gynoecium comprised flattened stigma with hairy edge. The mean length of style and ovary was 1.60 cm and 1.00 cm respectively. A distinct purple line (along the enclosing end of the standard petals) became visible at flower bud stage, when bud length reached 2.2 cm -2.7 cm. Anthesis occurred within 24 hours beyond this stage and petals dropped a day after anthesis. Certification of stigmatic receptivity and pollen fertility may be dependent on the above information. The present study further provides basis for the understanding of pollination mechanism and breeding system within the species.
