“…Stomatal conductance, as a key trait of photosynthetic leaf, influenced under water stress (Jiang et al 2006). Delay canopy senescence due to various light interceptions by the green leaf area was necessary for the productivity of hybrid maize under normal and drought stress (Cairns et al, 2012b). Several previous researches indicated that reduced canopy senescence and higher leaf chlorophyll are correlated with the increasing grain yield in well-watered temperate of hybrids (Lee & Tollenaar, 2007;Barutçular et al, 2016b).…”

“…Identification of phenotypic, ideotypes traits and donors are important in drought breeding progress (Cairns et al, 2012b). Therefore, the present research was undertaken to evaluate the effect of drought stresses on stomatal conductance and to determine the relationship between stomatal conductance and yield of maize hybrids under water irrigation regime.…”

This study was conducted to evaluate the adaptability of maize hybrids under water deficit condition by measuring of stomatal conductance with the corresponding yield of maize hybrids. Seven maize hybrids were grown at two different irrigation regimes (well water and deficit water conditions) at the agricultural research area of Cukurova University, Adana, Turkey. The results of study indicated that at drought stress (deficit water) remarkably influenced maize yield. The hybrid Sancia produced maximum grain yield under water deficient condition while 71May69 hybrid achieved the higher yield under wellwatered condition. Stomatal conductance was strongly correlated with grain yield in this study and higher stomatal conductance indicates higher grain yield, higher stomatal conductance at 7 days after pollination helps to increase grain yield. A positive and significant correlation between grain yield and stomatal conductance was observed at 7th and 21st days after anthesis (DAA). Moderately high stomatal conductance under stress condition helps to produce the highest grain yield. Based on the results, stomatal conductance can be used as selection criterion to identify the drought stress genotypes in maize under Mediterranean condition.

“…In Southern Africa this will be tolerance to drought stress at elevated temperatures [119], while in many parts of Asia, tolerance to both drought and water logging is becoming important [145].…”

“…However, plant breeders have been actively working towards producing cultivars better able to cope with climate change. The Drought Tolerant Maize for Africa project [145] has produced new drought tolerant hybrids [148], and drought tolerant germplasm which also has a higher level of tolerance to higher temperatures is also available [149]. Similarly, the Program for Africa's Seed Systems is seeking to promote the development of seed systems that deliver improved, locally adapted crop varieties to small-scale farmers and the uptake and use of released cultivars [150].…”

Climate Change: Seed Production and Options for Adaptation

et al. 2016

Food security depends on seed security and the international seed industry must be able to continue to deliver the quantities of quality seed required for this purpose. Abiotic stress resulting from climate change, particularly elevated temperature and water stress, will reduce seed yield and quality. Options for the seed industry to adapt to climate change include moving sites for seed production, changing sowing date, and the development of cultivars with traits which allow them to adapt to climate change conditions. However, the ability of seed growers to make these changes is directly linked to the seed system. In the formal seed system operating in developed countries, implementation will be reasonably straight forward. In the informal system operating in developing countries, the current seed production challenges including supply failing to meet demand and poor seed quality will increase with changing climates.

“…Variations in climate pose a significant threat to crop production and ultimately food security (Nhemachena and Hassan, 2007). The observed changes in climate are affecting crop yields differently in many regions, particularly within subSaharan Africa (Akpalu et al, 2008;Blignaut et al, 2009;Meza and Silva, 2009;Cairns et al, 2012). Rain-fed farming systems are the dominant source of staple food production and the livelihood foundation of the majority of the poor in sub-Saharan Africa, where investment in irrigation systems is low and scarce (Cooper et al, 2008).…”
