Biotic and abiotic stress. All the non-living environmental factors that can negatively or even harmfully affect the growth and productivity of plants and hence reduced crop yields. Future food and nutritional security would require.

Abiotic stress is the negative impact of non-living factors on the living organisms in a specific environment. An external condition that adversely affects growth development andor productivity. Bowie State University Maryland USA.

These keywords were added by machine and not by the authors. This necessitates identification andor development of suitable genotypes tolerant to these abiotic stresses. Shailendra Sharma Geneticsand Plant Breeding.

The details on role of biotechnology for crop improvement are available by Chopra and Narasimhulu 1990. The yield losses due to abiotic stresses may exceed 64 million tons those caused by biotic stresses 48 million tons. Additional budgetary support crucial for expanded raspberry and blackberry breeding capacity especially for host-plant response to biotic and abiotic stresses.

Stresses specially on drought and salinity sources of abiotic stress tolerance genetics of abiotic stress. Tolerance plant breeding presents the conventional selection and introduction. Biotic stress Stress that occurs as a result of damage done to plants by other living organisms such as bacteria viruses although they are not considered to be living organisms also cause biotic stress to plants fungi parasites beneficial and harmful insects weeds and cultivated or native plant For example browning of leaves on an.

Drought salinity temperature and heavy metals cause drastic yield reduction in most crops. Final crop yield can be really compromised if stress occurs in plants most sensitive phenological phases. Breeding for Resistance to Abiotic Stresses.

Being immobile and deprived of highly specialized immune system they have developed intricate mechanisms to adapt and survive under various types of abiotic and biotic stresses. Humphreys and Michael W. Abiotic stresses strongly affect plant growth development and quality of production.

The non-living variable must influence the environment beyond its normal range of variation to adversely affect the population performance or individual physiology of the organism in a significant way. Chickpea faces various abiotic stresses during its life cycle such as drought cold terminal heat and salinity Ryan 1997 Millan et al.
