“…Lysine content was found to be the highest in CP-16. The values reported here are in general agreements with those reported earlier in cowpea (Oluwatosin, 1997;Hussain and Basahy, 1998), mungbean (Gonzalez et al, 1964), soybean (Leverton, 1967), and pea (Wang and Daun, 2004).…”

Twenty one genotypes and two check varieties viz. CS-88 and V-240 of cowpea [Vigna unguiculata (L.) Walp. ] were screened for total proteins. The total protein content ranged from 22.4 (HC-3) to 27.9 % (HC-98-64) in 21 genotypes whereas in check varieties it was 25.6 (V-240) and 26.0 % (CS-88). Seven genotypes viz. HC-6, HC-5, CP-21, LST-II-C-12, CP-16, COVU-702 and HC-98-64 having high protein content (26.7 to 27.9 %) were selected for further characterization of their seed storage proteins. Globulins were the major protein fraction ranging from 55.6 (LST-II-C-12) to 58.8 % (CP-16 and HC-6) of total protein. Glutelins was the second major fraction ranging from 14.4 to 15.6 % followed by albumins (8.2 to 11.9 %) and prolamins (2.3 to 5.0 %). Content of free amino acids also showed variations amongst genotypes with COVU-702 having maximum and LST-II-C-12 having minimum content. Essential amino acid analysis revealed that S-amino acids (cysteine and methionine) were the first limiting amino acids followed by tryptophan. From the results presented here it could be suggested that two genotypes viz. LST-II-C-12 and HC-5 be used in breeding programmes aimed at developing high protein moth bean varieties with good quality.

“…Inter-varietal differences in protein content were also observed among the six arid legumes (Table 2). Environment has a significant influence on the protein content of grain legumes (Oluwatosin, 1997;Saxena et al, 2002;Frimpong et al, 2009). Intra-varietal and intra-plant variability in grain protein due to fluctuating environment was also observed (Gueguen and Barbot, 1988;Crochemore et al, 1994;Atta et al, 2004).…”

Grain protein content and protein profiles of six arid grain legumes belonging to three different tribes were studied. Average grain protein (per cent) of horse gram, cowpea, moth bean, guar, chickpea and green gram was 20. 29, 22.8, 22.6, 20.6, 21.82, and 20.40 respectively. All the six arid legumes were clearly differentiated based on the protein banding patterns generated through SDS-PAGE. The molecular weight range of proteins in different legumes was observed to be ~16 tõ 250kD. Interestingly, in chickpea, moth bean and horse gram proteins >100kD were not mostly observed. Further, distinct proteins were observed indicating inter-varietal differences in horse gram (CRHG-19), cowpea (RC-101) and guar , which could be useful in varietal identification. The different legumes were broadly clustered in to four clusters. Further, chickpea (Cicereae), green gram and cowpea (Phaseoleae) were clustered together. The similarity indexes of varieties and individual crops ranged from 0.667 to 0.950 and 0.425 to 0.821 respectively. Though the six legumes belong to Leguminosae they have distinct protein profiles which could be useful in species/varietal identification.

The genetic relationships among twenty phenotypically different cowpea landraces were unravelled regarding their suitability for preparing West African dishes. Amplified fragment length polymorphism classified unpigmented landraces (UPs) as highly similar (65%, one cluster), contrary to pigmented landraces (PLs, three clusters). UPs contained, in g kg À1 d.w., less fibre (24) and phenolics (3) than PLs (56 and 8, respectively) but had bigger seeds (200 g d.w. for 1000 seeds) and lower water absorption capacity at 30°C (1049 g kg À1 ) than PLs (139 and 1184, respectively). In g kg À1 d.w., protein (255), ash (39), calcium (0.95), phytate (9.3), iron (0.07) and zinc (0.04) contents were similar. UPs genetic similarities corroborated with their chemical composition and functionality clustered by principal component analysis. Therefore, UPs are well interchangeable regarding chemical composition and suitability for boiled and fried cowpea dishes in contrast to PLs. PLs have potential for innovative product design owing to their functional properties.
