Book Description
"An indispensable source for researchers, teachers, and graduate and postgraduate students interested in mutation breeding and genetic engineering. It introduces readers to contemporary knowledge and state-of-the-art technologies in the field of mutation breeding, including fundamental mechanisms and applications. . . . It will provide new directions, and avenues for enhancement of food security and food quality by using the latest techniques for the 'mutation as breeding' approach." - From Prof. Jameel M. Al-Khayri, King Faisal University, Saudi Arabia This comprehensive three-volume set book aims to help combat the challenge of providing enough food for the world by the use of advanced genetic processes to improve crop production, both in quantity and quality. Volume 1: Mutagenesis and Crop Improvement discusses mutagenesis, cytotoxicity, and crop improvement, covering the processes, mutagenic effectiveness, and mechanisms. The volume emphasizes the improvement of agronomic characteristics by manipulating the genotype of plant species, resulting in increased productivity. Volume 2: Revolutionizing Plant Biology covers the use of mutagenesis and biotechnology to explore the variability of mutant genes for crop improvement. The chapters deal with in-vitro mutagenesis to exploit the somaclonal variations induced in cell culture and highlight the importance of in-vitro mutagenesis in inducing salt resistance, heat resistance, and drought resistance. Volume 3: Mechanisms for Genetic Manipulation of Plants and Plant Mutants reviews the genetic engineering techniques used to mutate genes and to incorporate them into different plant species of cereals, pulses, vegetables, and fruits. Also discussed are the principles of genetic engineering by which desired genes can be transferred from plants to animals to microorganisms and vice versa.

Book Description
A survey was carried out to assess the farmers’ production constraints, traits and preferred cowpea varieties. A semi-structured questionnaire was used in a survey in Buhera District, Zimbabwe, in March and April of 2018. Women farmers dominated the survey as they were 52% of the surveyed population, while men occupied 48% of the total population. All participants concurred that cowpeas were used for domestic consumption. Eighty-three percent of the farmers cited shortage, unavailability, and cost of fertiliser, 16% of the farmers acknowledged that they do not have access to quality seed, and 1% cited labour as the major constraints in cowpea production. Farmers ranked heat (86%), drought (10%), and soil fertility (4%) as the most important abiotic factors. Ninety-one percent of the farmers’ ranked rust as the major disease, while 2% ranked storage rot, 1% ranked anthracnose, and 1% ranked downy mildew. Eighty-one percent of the farmers ranked aphids as the main pests, while 3% ranked thrips, 3% ranked legume borers, and 2% ranked pod borers. Fifty-two percent of the farmers preferred varieties that are resistant to diseases such as rust, whereas 48% were not concerned about diseases. For qualitative traits, 50% of the farmers had no specific colour preference, 32% preferred white colour, 14% brown colour, 3% red colour, and 1% tan colour. Ninety-four percent of interviewed farmers were not concerned about the pod shape, 3% preferred the kidney shape, 2% preferred the spherical shape and 1% preferred the globular shape. Ninety-nine percent of farmers agreed that they needed high yielding varieties per unit area and only 1% were unsure. For quantitative traits such as grain size, pod size, plant height, and head size, the preferences of farmers varied. Forty-four percent of the farmer respondents preferred larger cowpea grains, while 56% were not concerned about the size of the grain. A paltry 2% of the farmers were interested in pod size, while 98% did not regard it as important. Thirteen percent of the farmers were interested in climbing varieties, while 87% considered high grain yield as of the utmost importance.
