Breeding for high water-use efficiency.
There is a pressing need to improve the water-use efficiency of rain-fed and irrigated crop production. Breeding crop varieties with higher water-use efficiency is seen as providing part of the solution. Three key processes can be exploited in breeding for high water-use efficiency: (i) moving more of the available water through the crop rather than it being wasted as evaporation from the soil ...
متن کاملReduced nighttime transpiration is a relevant breeding target for high water-use efficiency in grapevine.
Increasing water scarcity challenges crop sustainability in many regions. As a consequence, the enhancement of transpiration efficiency (TE)-that is, the biomass produced per unit of water transpired-has become crucial in breeding programs. This could be achieved by reducing plant transpiration through a better closure of the stomatal pores at the leaf surface. However, this strategy generally ...
متن کاملHigh-Throughput Genomics Enhances Tomato Breeding Efficiency
Tomato (Solanum lycopersicum) is considered a model plant species for a group of economically important crops, such as potato, pepper, eggplant, since it exhibits a reduced genomic size (950 Mb), a short generation time, and routine transformation technologies. Moreover, it shares with the other Solanaceous plants the same haploid chromosome number and a high level of conserved genomic organiza...
متن کاملMaize response to water, salinity and nitrogen levels: yield-water relation, water-use efficiency and water uptake reduction function
Water, salinity and nitrogen are the major factors affecting maize production in arid and semi-arid areas. The objectives of this study were to investigate the effects of different water, salinity and nitrogen levels on yield-water relationships, water use, water productivity (WP), water use efficiency (WUE) and water uptake reduction function by maize hybrid SC-704 in a semi-arid area and ...
متن کاملwater and nitrogen application levels for the optimum tomato yield and water use efficiency
this study was conducted to determine the effects of different water and nitrogen application levels on drip-irrigated tomato plants. the amount of water usage was based upon the pan evaporation from a screened (class “a”) evaporation pan. the treatments consisted of two irrigation intervals (i1= 5 days and i2= 10 days), three plant-pan coefficients (kcp1= 0.50; kcp2= 0.75 and kcp3= 1.00) and t...
