Gene Pool Diversity and Crop Improvement

Abstract

This book series provides complete, comprehensive and broad subject based reviews about existing biodiversity of different habitats and conservation strategies in the framework of different technologies, ecosystem diversity, and genetic diversity. The ways by which these resources are used with sustainable management and replenishment are also dealt with. The topics of interest include but are not restricted only to sustainable development of various ecosystems and conservation of hotspots, traditional methods and role of local people, threatened and endangered species, global climate change and effect on biodiversity, invasive species, impact of various activities on biodiversity, biodiversity conservation in sustaining livelihoods and reducing poverty, and technologies available and required. The books in this series will be useful to botanists, environmentalists, marine biologists, policy makers, conservationists, and NGOs working for environment protection.More information about this series at

Detection of Stable Elite Haplotypes and Potential Candidate Genes of Boll Weight Across Multiple Environments via GWAS in Upland Cotton

“…Cotton has an ancient history of cultivation dating back seven thousand years or more according to the oldest archeological evidence, which was found in Pakistan (Rajpal et al, 2016 ). Subsequently, the invention of the cotton gin in the late 18 th century caused massive growth in cotton production, and cotton gradually became an important cash crop (Sunilkumar et al, 2006 ).…”

Groundnut (Arachis hypogaeaL.) improvement in sub-Saharan Africa: a review

“…It was bred at the International Crop Research Institute for Semi-Arid Tropics, Patancheru, India (Table 3). Genetic variability available in cultivated and wild Arachis have been extensively exploited through conventional breeding to develop improved varieties (Singh and Nigam 2016;Sharma et al 2017b). Genetic variation for important traits such as plant height, number of primary branches per plant, number of mature and immature pods per plant, kernel yield per plant, hundred seed weight, haulm yield per plant and dry pod yield per plant have been reported in groundnut.…”

“…Mexican hirsuta groundnut landraces such as PI576633, PI576634, PI576635, PI576636, PI576637 and PI576638 were also identified to be superior in flavour and quality (Sanchez-Dominguez and Williams 1993). Many other sources of resistance to foliar diseases such as rust and late leaf spot were identified from South American landrace varieties (Singh and Nigam 2016). Several pure lines such as 48-7, 48-14, 48-15A, 48-21, 48-34, 48-35, 48-36, 48-37, 48-44, 48-45 and 48-70A with resistance to groundnut rosette disease were selections from landraces (Singh and Nigam 2016).…”

In pigeon pea and chickpea, landraces or their selections were released directly as cultivated varieties (Asthana et al 1996;Remanadan 1996).…”

The Prospects of gene introgression from crop wild relatives into cultivated lentil for climate change mitigation

“…The importance of CWRs in the breeding of novel cultivars with improved acclimatization ability to various biotic and abiotic stresses, and in broadening the genetic base of modern crops has been very well established. Therefore, efforts have been done globally to characterize and conserve these important genetic treasures for future crop protection and sustenance of agri-food systems ( Jarvis et al., 2008 ; Rajpal et al., 2016a ; Coyne et al., 2020 ; Dissanayake et al., 2020 ; García-García et al., 2021 ; Quezada-Martinez et al., 2021 ; Pratap et al., 2021 ; Renzi et al., 2022 ; Rajandran et al., 2022 ).…”
