Korarima [Aframomum corrorima (Braun) P.C.M. Jansen] is a spice crop native to Ethiopia. Understanding the extent and partitioning of diversity within and among crop landraces and their wild relatives is among the first steps in conserving and measuring their genetic potential. The present study is aimed at characterizing the population genetic structure and relationships between cultivated and wild korarima in the southwestern part of Ethiopia.

Evidence of introgression, the transfer of genetic material, between crops and their wild relatives through spontaneous hybridization and subsequent backcrossing has been documented; however, the evolutionary patterns and consequences of introgression and its influence on the processes of crop domestication and varietal diversification are poorly understood.

The wild relatives of crop species represent a potentially valuable source of novel genetic variation, particularly in the context of improving the crop’s level of tolerance to abiotic stress. The mechanistic basis of these tolerances remains largely unexplored. Here, the focus was to characterize the transcriptomic response of the nodes (meristematic tissue) of couch grass (a relative of barley) to dehydration stress, and to compare it to that of the barley crown formed by both a drought tolerant and a drought sensitive barley cultivar.

Barley is relatively sensitive to Aluminum (Al) toxicity among cereal crops, but shows a wide genotypic difference in Al tolerance. The well-known Al-tolerant mechanism in barley is related to Al exclusion mediated by a citrate transporter HvAACT1 (Al-activated citrate transporter 1). A 1-kb insertion in the promoter region of HvAACT1 gene results in a dramatic increase of its expression level, which only occurs in some Al-tolerant cultivars. However, Al-tolerant Tibetan wild barley accession XZ29 did not have the 1-kb insertion.

Cowpea (Vigna unguiculata L.) is the most important grain legume crop grown in tropical and subtropical regions of the world. In India cowpea is grown as sole, mix-crop, intercrop systems. Cowpea is however, the only pulse suited to both arid and semi-arid regions and adapted better than any other pulses in high rainfall regions. As a good source of proteins, calcium and iron, it is recognized for many routine uses of food, feed, forage, fodder, vegetable and a number of dishes prepared from its grains.

Inferable from the impressive populace of wild relatives and forebears, the hereditary base of harvests was peaceful wide before taming. Through the span of time, hereditarily uniform improved assortments supplanted the profoundly differing nearby cultivars and landraces. These high yielding assortments have restricted inconstancy to battle the impact of biotic and abiotic stresses not at all like the Crop Wild Relative (CWR), which is an enormous store of agronomically critical characteristics.

Sugarcane is one of the major commercial crops in India and its productivity is severely hampered by drought and red rot. It is essential to enhance the abiotic and biotic stress tolerance by exploiting novel and diverse source of germplasm for sugarcane improvement and sustain productivity. Of late considerable attention has been given to utilize Erianthus spp a wild relative of sugarcane. In this study, Erianthus procerus introgressed intergeneric hybrid and backcross hybrids were evaluated for water deficit stress and red rot resistance.

Interspecific hybrids between cultivars of pearl millet [Pennisetum glaucum (L.) R. Br.] with 2n = 2x = 14 and its wild relative Napier Grass [Pennisetum purpureum (K.) Schum] with 2n = 4x = 28, which have multicut behaviour, perennial nature, high biomass and drought tolerance traits for crop improvement, were obtained by cross hybridization. Twenty hybrid progenies were obtained and then examined based on the morphological traits. Nine of them were confirmed to be true interspecific hybrids.

Pre breeding include all such activities related to the identification of desirable genes from the wild and weedy relatives and other unadapted materials and transfer these traits to an intermediate set of materials that breeders can use further in producing new varieties for farmers. It is the first step of crop improvement programs. It is essential for linking genetic diversity arising from wild relatives and other unimproved materials and it consists of identifying a useful character, capturing its genetic diversity and putting those genes into usable form.

Domestication is the process in which plants are genetically modified over time by humans for traits that are more advantageous or desirable for humans. A set of morphological, biochemical, and physiological traits that distinguishes domesticated plants from their wild progenitor is known as domestication syndrome. Reduction/loss of means of dispersal reduction/loss of dormancy, compact growth habit, earliness, gigantism, photoperiod insensitivity, reduction/loss of toxic substances is the major elements of domestication syndrome.

This book is about the conservation of genetic diversity of wild plants in situ in their natural surroundings, primarily in existing protected areas but also outside conventional protected areas. A lot of effort has been dedicated to conserving plant biodiversity, but most of this has focused on rare plant communities or individual species threatened with extinction.

Increasing attention has also been given to dissecting and understanding diversity in relation to genes underlying important agronomic traits in a number of crops. Molecular phylogenetics and genetic diversity analysis can help to clarify the taxonomic identity and evolutionary relationships of the wild relatives of crop species. These methods can also help prevent misidentification and carefully plan effective germplasm management strategies.
