Book Description
Pigeon pea is one of the most important leguminous crop globally. However it is a neglected pulse crops in South Africa in terms of research and production. Most farmers grow local landraces with low yields and there is lack of diverse material. The objective of the study was to determine the presence of genetic diversity among the pigeon pea genotypes using quantitative and qualitative phenotypic traits. The trials were conducted in Mafikeng and Nelspruit in South Africa. The trials were laid out in randomised complete block designs replicated three times. The quantitative and qualitative phenotypic data were recorded according to pigeon pea descriptor list. The phenotypic data were analysed using analysis of variance, Pearson,Äôs correlations, principal component analysis, and biplots constructed using principal coordinate analysis, Shannon weaver diversity indices and frequencies. The results showed highly significant differences among the genotypes based on plant height, pod bearing and seed number per pod meaning there was vast genetic diversity among the genotypes. Seed yield was positively correlated with seed number per pod, seed number per plant and pod weight whereas pod bearing was negatively associated with hundred seed weight meaning improving seed yield will automatically improve other positively correlated traits. Principal component analysis showed five most important PCs contributing to a total variation of 84.7%. The traits that contributed to the most variation to the total variation observed were plant height, pod length, seed yield, pod bearing and days to flowering. The Shannon weaver indices ranged between 0.98 and 1.00 showing the presence of variation among the qualitative traits measured. The clustering grouped genotypes into three clusters with Tumia and ICEAP 00540 being the most diverse. The diverse genotypes can be used as parents for hybridization and development of transgressive segregants in breeding programmes. There was vast presence of genetic diversity among the pigeon pea genotypes evaluated.

Book Description
World health authorities recommend people maximize their protein intake through vegetable sources (such as pulses), and reduce protein intake from animal sources. Increasing vegetable protein intake has been shown to be positively associated with the reduction of both cardiovascular-disease-related mortality and all-cause mortality. Pulse consumption has been shown to improve satiety and metabolism of glucose and lipids, due to their high protein and fiber content, which makes their consumption ideal for preventing and managing obesity. In recent years, there has been increasing demand for pulses and pulse-based products in developed countries. Several large-scale collaborative research projects on pulse products have been initiated by government agencies. Similarly, established multinational food companies have developed pulse product units. Pulses: Processing and Product Development fulfills the need for a comprehensive book on processing and products of pulses. The book addresses a specific pulse with each chapter to meet a wide range of audiences from undergraduate students to consumers.

Book Description
The high nutritional value of pigeon pea explains its importance in the diet of smallholder farmers in Africa. Pigeon pea grain is used in many forms. Pigeon pea is consumed mainly as dhal (split-grain) by the Asian community in South Africa, while the African population uses the dry grain. The leaves and stems of pigeonpea serve as an excellent feed for livestock or as fuel wood. Low soil N often limits plant growth and symbiotic N2-fixation offers opportunity to overcome low soil N levels for increased crop yield. However, N is also known to be the most commonly deficient nutrient in soils. Biological N2-fixation is therefore a cheaper source of N for improving crop yields. Because symbiotic systems contribute great amounts of N input into natural and agricultural ecosystems, legume N2-fixation is considered cheaper source of N for poor farmers. It is also more sustainable and environmentally friendly compared to fertilizer N. Nitrogen-fixing microorganisms therefore provide an alternative to inorganic fertilisers which are expensive and not easily accessible to poor rural farmers. This study evaluated plant growth and symbiotic performance C accumulation, P nutrition and grain yield/quality in ratooned pigeon pea (Cajanus cajan L. Millspaugh) genotypes obtained from international crops research institute for semi-arid tropics.
