To bring a new genetically modified crop into the commercial market, it has been estimated to cost USD 136 million over 13 years. [9] This poses a problem for development, as only a small number of companies can afford to develop drought-tolerant crops, and it is difficult for research institutions to sustain funding for this period of time. [9]
Resistance to drought is a quantitative trait, with a complex phenotype, often confounded by plant phenology. Breeding for drought resistance is further complicated since several types of abiotic stress, such as high temperatures, high irradiance, and nutrient toxicities or deficiencies can challenge crop plants simultaneously.
Such methods include: researching on drought resistant crops, monitoring plant transpiration and reducing soil evaporation. [117] Drought resistant crops have been researched extensively as a means to overcome the issue of water shortage. They are modified genetically so they can adapt in an environment with little water. This is beneficial as ...
The drought-resistant seeds from Syngenta and DuPont are important because they are made using native corn traits, while Monsanto's seeds splice in traits from other plants.
Crop yield is also negatively effected by drought stress, the reduction in crop yield results from a decrease in photosynthetic rate, changes in leaf development, and altered allocation of resources all due to drought stress. [72] Crop plants exposed to drought stress suffer from reductions in leaf water potential and transpiration rate.
Vigna aconitifolia is a drought-resistant legume, commonly grown in arid and semi-arid regions of India. It is commonly called mat bean, moth bean, matki or dew bean. The pods, sprouts and protein-rich seeds of this crop are commonly consumed in India. Moth bean can be grown on many soil types, and can also act as a pasture legume.
The crisis has been exacerbated by an El Nino-induced drought that has hit many southern African nations. The government has estimated that 2.7 million people will go hungry this year, although ...
Teff is a C 4 plant, [5] which allows it to more efficiently fix carbon in drought and high temperatures, and is an intermediate between a tropical and temperate grass. [7] The name teff is thought to originate from the Amharic word ጠፍፋ teffa , which means "lost".
