“…culta), was induced in Japan in the 1960s through chronic irradiation of the cultivar 'Nijisseiki' and a resistant cultivar 'Gold-Nijisseiki' was released (Sanada et al, 1988;Ahloowalia, et al, 2004). The success of this programme led to radiation breeding of susceptible 'Shinsui' and 'Osa-Nijisseiki' cultivars resulting in resistant cultivars 'Kotobuki-Shinsui' and 'Osa-Gold' (Masuda et al, 1994;Nakagawa, 2009). The 'Osa-Gold' mutant has the added advantage of being self-compatible, eliminating the need to grow pollinators.…”

Fruit breeding is an ancient technology with dynamic current technology and an exciting future (Janick and Moore, 1975, 1996). In its broadest sense, fruit breeding refers to the purposeful genetic improvement of fruit crops through various techniques including selection, hybridization, mutation induction, and molecular techniques. Its origins trace to the domestication process in prehistory and antiquity, where useful species were chosen and cultivated, and improved by continuous selection (Janick, 2005, 2011). Much of the world fruit industry is still based on grower selection from chance seedlings as well as mutations (sports) and as a result many fruit species are characterized by a narrow germplasm base. Spontaneous hybridization between wild plants and cultivated clones was critical to the early domestication of fruits. The lengthy juvenile period and the large field space required to grow temperate fruits have imposed major limitations on conventional breeding and various molecular biological techniques have been employed to make fruit breeding easier. (Igarashi et al.2016). Marker-assisted selection (MAS) uses DNA markers to provide an early DNA-based evaluation of genetic performance potential of seedlings, with the aim of improving cost and/or genetic efficiency of seedling selection (Ru, et al., 2015). Transgenic technology has facilitated the development of fruit trees with resistance to fungal or bacterial diseases, improved fruit quality, or root stocks with better rooting or dwarfing ability. In recent years, new technologies for genetic improvement, such as transgrafting, and genome-editing, have emerged. (Mudge, et al. 2009; Jia and Wang 2014). Using these techniques, no foreign genes are present in the final product, and some of them show considerable promise for application to apple breeding. Furthermore, genome editing, by which only the target gene can be accurately modified, is emerging as a novel breeding technology. These new technologies will undoubtedly facilitate fruit breeding, and yield novel and attractive fruit cultivars.

“…Under such circumstances, tissue culture techniques offer best possible alternative for improvement and inducing variations and selection of variants for different needs. In fruit crops, mutagenesis has been used to induce many useful traits affecting plant size, blooming time, fruit colour, fruit ripening, self‐incompatibility and resistance to pathogens (Masuda et al., ; Sanada & Amano, ). Genetic variations can be induced either by specific treatments with physical or chemical mutagens or by tissue culture (Larkin, ).…”

This study deals with in vitro-induced mutagenesis and selection of Phytophthora tolerant lines of Citrus jambhiri and their regeneration. For in vitro-induced mutagenesis, cotyledons were treated with ethyl methane sulfonate (EMS) 100, 200 and 300 mm for different time durations viz. 1, 3, 6 and 9 hr. Callus cultures were established from EMS treated cotyledon explants on MS medium supplemented with 2.0 mg/L of 2,4-D and 500 mg/L of malt extract. Calli derived from cotyledon were challenged in vitro on selective MS medium containing 5%-100% of culture filtrate (CF) of the Phytophthora parasitica. Selected mutagen-treated calli showed resistance in vitro on media containing CF. Calli treated with 100 mm EMS for 6-hr duration showed tolerance (24%) up to 75% CF after 4th selection cycle. While, calli treated with 200 mm for 6-hr duration showed maximum tolerance (76%) up to 75% CF. Resistant calli were then transferred to MS regeneration medium for shoot bud regeneration. A dose-dependent decrease in the regeneration capacity of the selected calli was observed with the increasing concentration of the CF. In randomly amplified polymorphic DNA analysis, plantlets showed different banding pattern in comparison with the control plant, which confirms the presence of variations at genetic level.

“…In contrast, induced mutations change only one or a few specific traits of an elite cultivar, and can contribute to fruit improvement without upsetting neither the requirements of the fruit industry nor the consumers. In fruit crops, mutagenesis has already been used to introduce many useful traits affecting plant size, blooming time and fruit ripening, fruit color, self-compatibility, self-thinning, and resistance to pathogens (Visser et al, 1971;Janick and Moore, 1975;Donini, 1982;Broertjes and Van Harten, 1988;Spiegel-Roy, 1990;Spina et al, 1991;Brunner and Keppl, 1991;Masuda et al, 1997;Janick and Moore, 1996;Van Harten, 1998;Sanada and Amano, 1998).…”
