Cryopreservation of Fruit Genetic Resources-A Review

Abstract

Conserving the plant genetic resources through any means is of utmost importance to prevent the loss of plant biodiversity. Long-term storage using liquid nitrogen (LN) is usually adopted for developing long-term base collections of crops for use in the distant future. The fruit crops are commonly propagated through vegetative means and are majorly conserved as ex situ field gene banks, which require large areas and demand intensive field management. The need for repeated reculturing and chances of contamination during subcultures in in vitro banking necessitate a long-term contamination free conservation through cryobanking. Improved cryopreservation techniques will provide added security in the preservation of important woody plant germplasm formerly preserved only as field collections.

Advances in Blueberry (Vaccinium spp.) In Vitro Culture: A Review

“…By meticulously controlling the growth conditions and nutrient compositions in vitro, tissue culture laboratories can produce disease-free plantlets with enhanced vigor and productivity [7]. Moreover, tissue culture facilitates the conservation of plant genetic resources by providing a platform for the long-term storage and propagation of rare and endangered blueberry cultivars, thus safeguarding biodiversity and promoting genetic resilience in the face of evolving agricultural landscapes [93]. Plant genetic resources are potential sources for farming, experimenting, and plant conservation [94].…”

A Review on Role of Wide Hybridization in Crop Improvement

“…It plays a substantial role in transferring traits of interest like disease and insect resistance, improved quality, early growth, dwarfism, increased yield, abiotic stress tolerance in crop plants besides bringing changes in the mode of reproduction as well. Wide hybridization involving crop wild relatives and related taxa has gained momentum in the recent fruit crop improvement programs" [1]. Wide hybridization serves as a important tool in agricultural applications, facilitating the introduction of valuable traits that improve crop performance.…”

Genetic diversity of brinjal (Solanum melongena L.) and its wild relatives

“…In spite of huge morphological variability, brinjal is having narrow genetic base which is the result of the major bottleneck of domestication syndrome and crop improvement (Meyer et al, 2012). The wild relatives of brinjal are reported to have resistance and tolerance to biotic and abiotic stresses (Rotino et al, 2014;Anushma et al, 2018) which can meet the challenges in the face of climate change, but still remain neglected as a potential source for development of new cultivars in brinjal as in case of tomato (Diez and Nuez, 2008).…”
