“…The high adaptability, heritability, genetic variability and nutritive values reported of locally grown pulses (landraces) call for concerted efforts towards their genome manipulation and improvement. This notwithstanding, the need to complement these approach should not be overemphasized as more often than not, local farmers are deprived of these high yielding genotypes (Udensi et al, 2010(Udensi et al, , 2011a(Udensi et al, , 2011b.…”

Aims: It is utmost desire for plant breeders to know the extent of relationship between yield and its various components, which will inevitably facilitate selection of desirable characteristics. This research focused on computing the correlation coefficients and path coefficients of yield and its contributing traits in pigeon pea landraces Cajanus cajan (L.) Millsp. Methods: Seeds of two varieties of locally grown pigeon pea were sown in a randomized complete block design (RCBD) in ten replications. The field study was done at the growing season. Correlation coefficients and path coefficients (partitioned into direct and indirect effects) were estimated on yield and its contributing traits. Results: Correlation results revealed that there was significant positive correlations between plant height plant -1 and number of leaves plant -1 (0.926**), leaf area plant -1

“…Owing to the inadequate supply, coupled with the high cost of protein rich foods of animal origin in the sub-Saharan African countries, exploration and exploitation of inexpensive and highly adapted alternative sources of protein of plant origin (Rajeev and Sridhar, 2008;Udensi et al, 2012a) becomes a sine qua non for increased life expectancy. According to Nielsen, (1991), Tharanathan and Mahadevamma (2003); Udensi et al (2011b), legumes are valuable sources of complex carbohydrates, protein and dietary fibers. They also contribute significant amount of vitamins and minerals and high energy value.…”

“…They also contribute significant amount of vitamins and minerals and high energy value. Interestingly, protein contents in legume grains range from 17-40% contrasting with 7-13% of cereals and being equal to the protein content of meat (18-25%) (de Almeida Costa, et al, 2006;Udensi et al, 2011b). Crop development, improvement and preservation are very pivotal in the sustainability and food security of the Sub-Saharan African countries especially, Nigeria (Udensi et al, 2012b).…”

Aim: Effects of gamma irradiation on amino acid profile, proximate and anti-nutritional compositions of selected landraces of pulses were investigated. Methods: Seeds of Brown "Fiofio", White "Fiofio" (Cajanus cajan) and "Olaudi" (Vigna unguiculata) were exposed to gamma irradiation. Each variety was divided into five groups of fifty grams weight and was exposed to 200, 400, 600, 800Gray (Gy) doses of gamma irradiation from Cobalt 60 source while the fifth group served as control. Results: Our results revealed that the proximate, anti-nutritive factors and amino acid profile were significantly (P<0.05) reduced with increasing gamma irradiation dose. Though percentage germination was not significantly (P>0.05) affected, there was delayed germination and survival percentage became zero percent on exposure to 400Gy and above. "Olaudi" variety was less affected by the gamma rays exposure going by the result of the days to seedling emergence and percentage survival, making pigeon pea species more sensitive to the irradiation. Conclusion: Taking the results together, it does importantly suggest, however, that lower doses of gamma irradiation might be preferred for achieving the dual purpose of improvement and preservation but high enough to reduce the anti-nutritional factors.

“…A complementary strategy could be to provide alternatives in the panel of grain legumes potentially cropped or processed by identifying new species from worldwide grain legume biodiversity and creating new niches for these species and a renewed interested in grain legumes. This strategy can rely on the one hand, on the adaptability of grain legumes to new environmental conditions [22,23] and on the other hand, on the interest of the supply chain in new plant-based products, as occurred in the case of quinoa [24,25]. In this paper, our goal is to explore the latter strategy.…”

In the Global North, there is an increasing interest in pulses both for their beneficial effects in cropping systems and for human health. However, despite these advantages, the acreage dedi-cated to pulses has been declining and their diversity reduced, particularly in European temperate regions, due to several social and economic factors. This decline has stimulated a political debate in the EU on the development of plant proteins. By contrast, in the Global South, a large panel of minor pulses is still cropped in regional patterns of production and consumption. The aim of this paper is to investigate the for cultivation of potential minor pulses in European temperate regions as a complement to common pulses. Our assumption is that some of these crops could adapt to different pedo-climatic conditions, given their physiological adaptation capacity, and that these pulses might be of interest for the development of innovative local food chains in an EU policy context targeting protein autonomy. The research is based on a systematic review of 269 papers retrieved in the Scopus database (1974–2019), which allowed us to identify 41 pulses as candidate species with a protein content higher than 20% that are already consumed as food. For each spe-cies, the main agronomic (e.g. temperature or water requirements) and nutritional characteristics (e.g. proteins or antinutritional contents) were identified in their growing regions. Following their agronomic characteristics, the candidate crops were confronted with variability in the annual growing conditions for spring crops in European temperate areas to determine the earliest poten-tial sowing and latest harvest dates. Subsequently, the potential sum of temperatures was calcu-lated with the Agri4cast database to establish the potential climatic suitability. For the first time, 21 minor pulses were selected to be grown in these temperate areas and appear worthy of inves-tigation in terms of yield potential, nutritional characteristics or best management practices.
