Phenotyping maize for adaptation to drought
Araus JL, Serret MD, Edmeades GO (2012). Phenotyping maize for adaptation to drought. Frontiers in Plant Physiology 3:305. (DOI: 10.3389/fphys.2012.00305).
The need of a better adaptation of crops to drought is an issue of increasing urgency. However, enhancing the tolerance of maize has, therefore, proved to be somewhat elusive in terms of plant breeding. In that context, proper phenotyping remains as one of the main factors limiting breeding advance. Topics covered by this review include the conceptual framework for identifying secondary traits associated with yield response to drought and how to measure these secondary traits in practice.

Bridging the phenotypic and genetic data useful for integrated breeding through a data annotation using the Crop Ontology developed by the crop communities of practice
Shrestha R, Matteis L, Skofic M, Portugal A, McLaren G, Hyman G and Arnaud E (2012). Bridging the phenotypic and genetic data useful for integrated breeding through a data annotation using the Crop Ontology developed by the crop communities of practice. Frontiers in Physiology 3:326 pp. 1–10. (DOI: 10.3389/fphys.2012.00326). (G4009.03/G4010.06/G4011.01/G4011.10).
The Crop Ontology (CO) of the Generation Challenge Programme (GCP) (http://cropontology.org/) is developed for the Integrated Breeding Platform (https://www.integratedbreeding.net/) by several centers of The Consultative Group on International Agricultural Research (CGIAR): Bioversity, CIMMYT, CIP, ICRISAT, IITA, and IRRI. Integrated breeding necessitates that breeders access genotypic and phenotypic data related to a given trait. The Crop Ontology provides validated trait names used by the crop communities of practice for harmonizing the annotation of phenotypic and genotypic data and thus supporting data accessibility and discovery through web queries.

Phenotyping chickpeas and pigeonpeas for adaptation to drought
Upadhyaya HD, Kashiwagi J, Varshney RK, Gaur PM, Saxena KB, Krishnamurthy L, Gowda CLL, Pundir RPS, Chaturvedi SK, Basu PS and Singh IP (2012). Phenotyping chickpeas and pigeonpeas for adaptation to drought. Frontiers in Plant Physiology 3:179. (DOI: 10.3389/fphys.2012.00179).
The chickpea and pigeonpea are protein-rich grain legumes used for human consumption in many countries. Grain yield of these crops is low to moderate in the semi-arid tropics with large variation due to high GxE interaction. In the Indian subcontinent chickpea is grown in the post-rainy winter season on receding soil moisture, and in other countries during the cool and dry post winter or spring seasons. The pigeonpea is sown during rainy season which flowers and matures in post-rainy season. The rainy months are hot and humid with diurnal temperature varying between 25 and 35˚C (maximum) and 20 and 25˚C (minimum) with an erratic rainfall. The available soil water during post-rainy season is about 200–250 mm which is bare minimum to meet the normal evapotranspiration. Thus occur- rence of drought is frequent and at varying degrees. To enhance productivity of these crops cultivars tolerant to drought need to be developed.

Phenotyping for drought tolerance of crops in the genomics era
Tuberosa R (2012). Phenotyping for drought tolerance of crops in the genomics era. Frontiers in Plant Physiology 3:347. (DOI: 10.3389/fphys.2012.00347).
Improving crops yield under water-limited conditions is the most daunting challenge faced by breeders. To this end, accurate, relevant phenotyping plays an increasingly pivotal role for the selection of drought-resilient genotypes and, more in general, for a meaningful dissection of the quantitative genetic landscape that underscores the adaptive response of crops to drought. A major and universally recognized obstacle to a more effective translation of the results produced by drought-related studies into improved cultivars is the difficulty in properly phenotyping in a high-throughput fashion in order to identify the quantitative trait loci that govern yield and related traits across different water regimes. This review provides basic principles and a broad set of references useful for the management of phenotyping practices for the study and genetic dissection of drought tolerance and, ultimately, for the release of drought-tolerant cultivars

Taking thirty-seven hexaploid wheat (AABBDD) accessions with different drought resistance at seedling stage, three wheat species with A genome (AA), and three tetraploid wheat species (AABB) as test materials, and by direct sequencing the single nucleotide polymorphism (SNP) in TaCRTA, this paper analysed the relationships of the SNP with the drought resistance of wheat (Triticum aestivum) at its seedling stage, and mapped the TaCRTA on the chromosome of wheat.

This paper is a section of the book “Drought phenotyping in crops: from theory to practice” (Monneveux Philippe and Ribaut Jean-Marcel eds, published by CGIAR Generation Chal-lenge Programme. Texcoco, Mexico). The section describes recent experience in drought phenotyping in rice which is one of the most drought-susceptible crops. The section contains genetic and genomic resources for drought adaptation and methods for selection of drought-resistant varieties in rice. In appendix, there is experience from Thailand on integration of direct selection for grain yield and physiological traits to confer drought resistance.

Shi W, Chang X, Jing R (2012). Gray association grade analysis of physiological traits with yield of wheat under different water regimes. Journal of Triticeae Crops 32(4):653–659. (G7010.02.01). Article in Chinese with abstract in English. Not open access: view online
The purpose of the present research is to reveal the variation of canopy temperature and photosynthetic characteristics and their impact on wheat (Triticum aestivum L.) yield under drought stress. A set of introgression BC3F5 lines (ILs) generated from repeated backcross [(Lumai 14 X Jinmai 47) X Lumai 14] were used as the plant materials. The donor parent Jinmai 47 was a drought tolerant cultivar, the recurrent parent Lumai 14 as a high yield potential cultivar under well-watered condition.

An identification and evaluation for 1 000 seed weight, grain number per ear, ear number per plant, plant height, plumpness of kernels and yield of 146 wheat germplasms from GCP projects were conducted. The results showed that: the tested varieties had a wealth of genetic diversity in yield, grain number per ears, ear number per plant and so on; there were different correlations in each trait; heading and maturity stages had effects to grain number per ear, yield and 1 000 seed weight. We had successfully selected 8 big ear fertility varieties, 8 big grain fertility varieties, 5 short stalk fertilities and 25 fine varieties of super traits and outstanding fertility.
