Breeding Maize for Drought Tolerance in the US Corn-Belt
The objective of this review is to promote discussion on some of the key issues we consider to be involved in successful long-term genetic improvement of corn for drought tolerance. Many of the concepts have been discussed elsewhere for different crops, traits and different breeding targets. Here we focus on how to organize a comprehensive effort to enable breeding for drought tolerance in a he...
متن کاملUse of Genomic Estimated Breeding Values Results in Rapid Genetic Gains for Drought Tolerance in Maize.
More than 80% of the 19 million ha of maize ( L.) in tropical Asia is rainfed and prone to drought. The breeding methods for improving drought tolerance (DT), including genomic selection (GS), are geared to increase the frequency of favorable alleles. Two biparental populations (CIMMYT-Asia Population 1 [CAP1] and CAP2) were generated by crossing elite Asian-adapted yellow inbreds (CML470 and V...
متن کاملEffect of Drought in the Osmotic Adjustment of Cotton Plants
Water is crucial for crop growth and productivity. Cotton metabolism and yield are compromised under drought conditions, especially at flowering stage. Differences in drought tolerance exist among cultivars but the metabolic reasons for this that could be used to find traits for enhancing drought tolerance have not been clearly elucidated. Under drought stress, osmotic adjustment occurs in plan...
متن کاملThe genetics of drought tolerance in conifers.
Contents 1034 I. 1034 II. 1035 III. 1037 IV. 1038 V. 1042 VI. 1043 VII. 1045 References 1045 SUMMARY: As temperatures warm and precipitation patterns shift as a result of climate change, interest in the identification of tree genotypes that will thrive under more arid conditions has grown. In this review, we discuss the multiple definitions of 'drought tolerance' and the biological processes in...
متن کاملMechanisms of Drought Resistance in Grain Legumes I: Osmotic Adjustment
When crops are exposed to drought there is commonly an increase in solute-pool of the plant tissue. A series of experiments were conducted in 1994 and 1995 in the University of Hohenheim, Germany, to evaluate whether drought-induced solute accumulation per se will improve drought resistance, to determine the species of active osmotica involved, and to identify alternative mechanisms in grain le...
