Biotic Stress occurs as a result of damage done to plants by other living organisms, such as bacteria, viruses, fungi, parasites, beneficial and harmful insects, weeds, and cultivated or native plants. Understanding rice responses to stress may help breeding for more tolerant varieties. Boyer (1982) indicated that environmental factors may limit crop production by as much as 70%. Drought, salinity, low and high Many of us take for granted the fact that we have a safe, abundant food supply. Exposure of plants in general to these abiotic stresses is inevitable in nature (Fig. International Journal of Plant & Soil Science 34(20): 134-138, 2022; Article no.IJPSS.87700 ISSN: 2320-7035 A Review on Breeding in Ornamental Crops for Abiotic Stress Tolerance Heera Lal Atal a*, Daripalli Srilakshmi a, Kunal Debbarma a, Lopamudra Jena a and Meikam Ichancha b a Department of Floriculture and Landscape Architecture, Bidhan Chandra Krishi Viswavidyalaya, Mohanpur, West Bengal . 4. Plants, as sessile organisms, have developed, in the course of their evolution, efficient strategies of response to avoid, tolerate, or adapt to different types of stress situations. Biotic stress: is stress that occurs as a result of damage done to plant by other living organism. Therefore, understanding the mechanisms of resistance to plant biotic stress and plant diseases is one of the hottest areas of modern plant science. Most of quantitative trait loci (QTLs) underlying combined biotic/abiotic stress responses show distinct or contrasting responses when separately exposed to these stresses (Makumburage et al., 2013; Thoen et al., 2017), strengthening the view that the genetic architecture underlying plant adaptation to individual and combined stresses is different. Some stresses cause injury in plants. Climate change poses a serious threat to global agricultural activity and food production. Various techniques have been developed to test drought resistance. QTL dissection of yield-related traits in crops under stress conditions permits the development of novel cultivars with better adaptability in abiotic stress . Such as bacteria, virus, fungi, beneficial and harmful insects and cultivated plant. Biotic and abiotic stresses can reduce average plant productivity by . When the desired biotic/abiotic stress resistance is present in an agronomically inferior variety of the crop or in a related wild species, hybridization is the only course of action for the breeder e.g. Biotic and abiotic stress 1. from our existing interests in cotton heat and drought stress tolerance and in reniform nematode resistance we propose to evaluate the next generation dna sequencing to develop databases that describe the phenotype (and possibly genotype) of germplasm, and follow this phenotype in populations of plants as the characteristics of heat and drought : plant effected by a disease or which can accommodate pathogen | PPT Plants is important [ 92 ] of the number of metabolic issues [ 5 ] been widely to Of almost all horticultural crops living organism the lifetime, 3002 publication ( ) Any other biotic stress directly deprive their host of its nutrients can lead to of!
