High heritability and moderate to high genetic gain was observed for all the characters in all the cuttings except for moisture content. Chlorophyll a exhibited highest correlated response for the I st and III rd cutting while fibre content had highest correlated response for the II nd cutting. A multiple selection index is suggested to enhance foliage yield. The estimates of correlated response and relative selection efficiencies were in proportion with each other though relative selection efficiencies were less than one.

This breeding methodology is highly desirable in situations where farmers are generally less served by formal breeding programs. PPB offers advantages like it saves time, improves farmer seed systems and seed provision to small-scale farmers, enhances biodiversity, improves research, and accelerates adoption by the farmers. It enhances the farmers’ organizational and social capital, as well as individual farmers’ knowledge and skills and capacity to learn and experiment. In spite of limited involvement, rural women seem to have derived the maximum benefits from the PPB approach leading to gender empowerment. However, protagonists argue that inclusion of participatory approaches would increase complexity and lead to increase in time and cost due to aspects like training of farmers, more exhaustive testing of varieties, requirement of large amount of seeds, conduction of trials outside the experimental fields, and requirement of diverse manpower to effectively communicate with farmers.

However, in spite of immense turnaround in productivity through Green Revolution, conventional plant breeding has done little to improve the life of subsistence farmers across continents. Formal breeding programs have primarily catered the well-off farmers, and the poor farmers have not reaped the desired benefits. The poor and marginal farmers of the developing countries are faced with problems like inequitable land distribution, insecure ownership, fragmentation of holdings, inadequate irrigation, poor credit facilities, improper marketing, and slow growth of allied sectors remained aloof from this spectacular phenomenon. Participatory plant breeding (PPB) is the development of a plant breeding program in collaboration between breeders and farmers, marketers, processors, consumers, and policymakers. In PPB, farmers and researchers work in tandem with farmers taking a lead role in the design, implementation, and evaluation of the breeding material. The chapter discusses at length the different forms of farmers' participation in crop improvement.

Ionic toxicity, osmotic stress, and nutritional defects under severe salt stress may lead to metabolic imbalances and resultant oxidative stress. Amaranthus spp. have been cultivated for centuries as a grain and foliage crop in many parts of the world due to the high nutritional value of its leaves and seeds as well as its resistance against both biotic and abiotic stresses like heat, drought, diseases, and pests. Many species of the genus have been reported to tolerate adverse environmental stresses which have been associated with their C4 physiology, indeterminate flowering habit, long tap root system, extensive lateral root system, accumulation of compatible solutes, efficient water usage, and the expression of stress-related genes and transcription factors. This chapter presents an updated account of the various reports available with respect to salinity stress in this underutilized crop.

Correlated response (CR) and relative selection efficiency (RSE) were estimated for grain yield and three quality components, grain protein, grain carotenoid and leaf carotenoid based on different contributing traits. Stem diameter, chlorophyll a, total chlorophyll and leaf carotenoid had high CR and RSE values for grain yield indicating the effectiveness of these traits in increasing grain yield. Grain protein and grain carotenoid exhibited negative CR and RSE values for grain yield indicating that direct selection for grain yield would lead to a slight decrease in these quality characters. Grain size was not of much significance either in increasing grain yield or any of the quality components. Grain yield can also be increased through indirect selection for stem diameter, while leaf pigments are likely to play a...

The earliest fossils of Homo sapiens are located in Africa and dated to the late Middle Pleistocene. The hunter-gatherers dominated the scene across all continents until the end of the Pleistocene. Thereafter, food production based on domestication of relatively few wild species (both plant and animal) took the center stage. Agriculture was thought to be a significant improvement over the hunter-gatherer mode of living since it was more convenient to grow a dependable food source rather than collect plants from the wild. Domestication, an accelerated evolutionary process driven by human intervention and natural selection, was a unique form of mutualism that developed between humans and the target plant or animal population and had strong selective advantages for both the partners. During the domestication process,...
