A Review on Breeding in Ornamental Crops for Abiotic Stress Tolerance

Abiotic stresses are major concerns in agriculture sector affecting large parts of India. It is caused by Drought, salinity and temperature (high/low) representing a major constraint over crop growth rate and productivity. In ornamental crops meagre efforts have been done towards this way. Now a day’s ornamental crops are the prospective way to earn higher income as compared to the other crops and have a significant role in national GDP. How can we grow Ornamental crops in stressed condition is one of the major challenge. To get tolerance power against abiotic stress various ways have been developed but among all methods very few have been proved worthy in case of ornamental crops. Interspecific and intergeneric hybridization is the basic way found hopeful strategy to improve tolerance against drought in some crops through domesticating abiotic stress-tolerant gens from their wild species into cultivated. Combination of both tissue culture and induces mutation approach (In vitro mutagenesis) is the one more important way for bringing stress tolerance and improvement in yield and quality of Ornamental crop plants. Genetic engineering is the modern tool which is used for breeding programme. The introduction of innovative characteristics such as new colours, biotic and abiotic stress tolerance in ornamental crops are usually difficult through predictable breeding, but by the use of genetic transformation we can get is easily.
