Nine accessions of Bambara groundnut (Vigna subterranea (L.) Verdc.,syn. Voandzeia subterranea (L.) Thouars ex DC.)  obtained from National Centre for Genetic Resources and Biotechnology (NACGRAB), Ibadan, Oyo state, were assessed for their genetic and phylogenetic relatedness through electrophoretic analysis of the seed proteins. 0.2g of the seeds were weighed and macerated with mortar and pestle in 0.2M phosphate buffer containing 0.133M of acid (NaH2PO4) and 0.067 of base (Na2HPO4) at pH 6.5. Protein characterization with standard marker revealed that the seeds of the nine accessions contained proteins (B.S.A, Oval Albumin, Pepsinogen, Trypsinogen and Lysozyme) with molecular weights ranging from 66kda and above, 45 – 65 kDa, 44 – 33 kda, 32-24 kDa and 23-14 kDa, respectively. The student T-test revealed that accessions B, C, E, F, H and I have molecular weights not significantly different from one another (P<0.05) while samples A, D and G showed significantly different values (P>0.05). All the accessions had at least two proteins and two major bands in common. The study revealed intra-specific similarities and genetic diversity in protein contents among the nine accessions of Bambara groundnut (Vigna subterraranea (L.) Verdc.syn

Random amplified polymorphic DNA (RAPD) markers were used to assess genetic diversity in Bambara groundnut (Vigna subterranea L.) germplasm using 25 African accessions from the collection in the International Institute for Tropical Agriculture, Ibadan, Nigeria. Fifty random decamer primers were screened to assess their ability to detect polymorphism in bambara; 17 of them were selected for this study. Considerable genetic diversity was found among the V. subterranea accessions studied. The relationships among the 25 accessions were studied by cluster analysis. The dendrograms showed two main groups of accessions mainly along the lines of their geographic origin. It is concluded that RAPD can be used for germplasm classification in bambara groundnut and hence for improving this crop.Key words: germplasm, PCR, RAPD, Vigna subterranea.

Abstract. Fatimah S, Ariffin, Rahmi AN, Kuswanto. 2020. Tolerance and determinants of drought character descriptors of the Madurese landrace bambara groundnut (Vigna subterranea). Biodiversitas 21: 3108-3116. Bambara groundnut (Vigna subterranea L. Verdc.) is legume of African origin overlooked in Indonesia. It has underdeveloped in Indonesia; for example, in East Java, it is only cultivated in Gresik, Lamongan, and Bangkalan of Madura. This plant can potentially be developed in dry lands, such as Madura as it has the ability to grow and develop well in a dry environment with low nutrient level. At present, there are sparse researches on the selection and determination of the drought-tolerant character descriptors of bambara groundnut in Indonesia. The present study used the expected lines of bambara groundnut selected from local lines of various regions in Indonesia using the nested design. The results showed that the drought stress treatment led to stunted growth of 12 bambara groundnut genotypes, including the number of leaves, plant height, canopy diameter, leaf thickness, number of flowers, number of stems or branches, number of internodes, length of leaf stems, root length, root wet weight, canopy wet weight, canopy dry weight, root dry weight, and leaf chlorophyll content. However, drought leads to a slight increase in the width and length of the stomata opening and leaf proline contents. The cluster analysis based on stress index and sensitivity index can classify 3 expected lines originating from Gresik Regency (G1, G2, G3), falling into the drought stress-tolerant category. Accumulated proline contents cannot be used as a descriptor of tolerance to drought stresses in bambara groundnut since the expected lines with an increase in proline contents in leaves during drought stresses based on the cluster analysis do not fall into the genotypic cluster tolerant to drought stresses.

The nutrient composition and the acceptability of biscuit from composite flours of wheat, Bambara groundnut (Vigna subterranea), Ground bean seed (Macrotyloma) and Moringa seed (Moringa oleifera) were evaluated. Bambara groundnut (Vigna subterranea), Ground bean seed (Macrotyloma) and Moringa seed (Moringa oleifera) were dried, and processed into flour. The flour blends developed was used as a substitute for wheat flour as composite flour. The resulting mixtures were then used to produce biscuits at different ratios of wheat flour to flour blends; 100:0, 90:10, 80:20 and 70:30 level of the flour blends. The pasting properties, proximate composition, minerals, physical (spread ratio, weight, thickness and colour) and sensory properties of the composite biscuit were evaluated. The pasting properties of the flours showed that pasting temperature ranged from 68.50°C - 70.0°C and the peak viscousity range from 101.17 RVU – 207.17 RVU, while Break down (43.0 RVU) was highest in 90% wheat: 10% (Bambara- groundnut-ground bean seed- moringa seed flour) (WFF1). The protein content increased from 12.50% in the control (100% wheat flour) to a range of 14.40% - 16.19% in the biscuits; crude fibre decreased from 2.83 to 2.40 - 1.84%, ash content increased from 1.26% to a range of 1.53 - 2.01%, while carbohydrate and energy value reduced from 69.20 to 65.54 - 63.36% and 384.04 Kcal/100 g to 391.34 - 391.55 Kcal/100 g respectively. As the ratio of blends level increase, the thickness, diameter and weight increased but the spread ratio decreased. In conclusion incorporation of bambara groundnut, ground bean seed and moringa seed flour blends played important role in enhancing the nutritional properties of biscuits through improving their protein content, energy value and mineral elements especially calcium and potassium.

Mineral Compositions

The study aimed to assess variation in mineral compositions of some accessions of Bambara groundnut (Vigna subterranea [L.] Verdc.) for domestic use and genetic enhancement. Twenty accessions of Bambara groundnut were planted in a Randomised Complete Block Design (RCBD) with three replications. The five minerals were analysed which include, calcium, magnesium, iron, zinc and manganese. These accessions showed significant (P?0.05) variations across the five mineral analysed. Accession no. 18 had the highest mean for iron (2.89 mg100g-1), Accession no. 12 had the highest mean value for zinc (0.65 mg100g-1) Accession no. 8 had the highest mean value for calcium (217.36 mg100g-1), magnesium (14.29 mg100g-1)and manganese (0.82 mg100g-1). However, accession no. 12 had the lowest mean values in four of the minerals except zinc. This result showed that some of these accessions could be selected for genetic enhancement of minerals, some for domestic use and some for industrial use.

Seed Dormancy And Germination

Bambara groundnut seeds often show unsynchronized and slow germination even though on newly harvested seeds. This might be due to the presence of seed dormancy. Therefore, the objective of this research was to obtain the information on seed dormancy and germination behaviour of bambara groundnut seeds during desiccation. The experiment was arranged in a nested design. Dormancy breaking treatments (untreated, mechanical scarification, soaking in 1% KNO3 for 2 hours, mechanical scarification followed by KNO3 soaking) were nested in each of the desiccation levels (fresh seeds with 54.7% moisture content (mc), desiccated seeds with 44.4%, 18.0%, 15.4%, and 12.1% mc). The results showed that newly harvested seeds were in dormant state. Seed desiccation did not increase the intensity of seed dormancy, even resulted in an increase in field emergence (at 30 days after planting) from 43.9% in fresh seeds to around 70% in dry seed (12-15% mc). Seed desiccation (from 44.4% mc to 12.1% mc) increased the field emergence, although it was inadequate to break the dormancy completely. Meanwhile, seed desiccation tended to increase the GA/ABA ratio, but the seed permeability was decreased. The fact showed that seed desiccation reduced the intensity of dormancy of bambara groundnut seed, therefore, it is suggested to modify the drying method in order to accelerate the increasing of GA/ABA ratio while keeping the testa permeable.
