  This study investigated the nutritive value of locally grown pulses’ landraces (White “Fiofio”, Brown “Fiofio”, [Cajanus cajan (L.) Millsp] “Olaudi” “Akidi” and IT88D-867-11) [Vigna unguiculata (L) Walp] as indices for conservation and improvement. Proximate, anti-nutritional and mineral elements were evaluated. Data analyses were done using analysis of variance. Results showed that there were significant differences (p<0.05) in the proximate compositions of the screened pulses, except in the ash content which shows no significance among the pulses (p>0.05). The moisture content did not differ among the brown and white “Fiofio”, “Olaudi” and IT88D-867-11 but differed significantly from “Akidi”. Results obtained also revealed that there was no significant difference (p>0.05) in the protein contents of brown “Fiofio”, “Akidi” and IT88D-867-11 but differed slightly from white “Fiofio” and “Olaudi”. Additionally, “Olaudi” had the highest protein content in its seeds. There was no significant difference in the carbohydrate content among brown “Fiofio”, “Olaudi” and “Akidi” but differed from white “Fiofio” and IT88D-867-11. Present results on the anti-nutritive contents also showed that there were significant differences (p<0.05) among the five sampled pulses. “Akidi” had the highest phytic acid level which was followed by IT88D-867-11. There was no significant difference in the hydrocyanide content of “Akidi”, “Olaudi” and IT 888D-867-11. This component was highest in brown “Fiofio” and least in white “Fiofio”. The oxalate content was highest in “Akidi”. Comparing other pulses with IT88D-867-11, the landraces contained higher mineral elements. For the vitamins, IT88D-867-11 contained the highest level of Vitamin A but had the least Vitamin C. Coupled with their high adaptability in adverse climatic conditions, it is explicitly obvious that these landraces should be selected for conservation and improvement.

  The negligence of breeders and farmers to explore and exploit landraces of pulses is worrisome and urgent measures needed to be set in motion to forestall major future crisis, taking into cognizance the high adaptability and nutritive values accredited to them. This study focused on the estimation of genetic variability and heritability of desirable morphological characters in Fiofio (Cajans cajan) and Olaudi and Akidi (Vigna unguiculata) with the aim of conservation. Three landraces of pulses were sown using randomized complete block design. The field experiment was carried out at the University of Calabar Experimental Farm, University of Calabar, Calabar, during 2008-2010 growing season. Phenotypic and genotypic variances and coefficients of variation and genetic advance were estimated on yield and yield-related traits. The results showed that there were considerable variations among the pulses for the traits studied. The result revealed high genetic variability in the number of leaf per plant, leaf area, number of flowers per plant, number of pods per plant and number of seeds per plant. It also showed that genetic variability in pod length and 100-seed weight was low. Heritability estimates obtained in the result were very high though the magnitude of genetic variability in the yield and yield-related traits was not proportional to the heritability estimates. The traits studied also show high genetic advance. These explicitly showed that there are sufficient genetic variations to warrant conservation and improvement in these extinction-threatened pulses studied.
