Approaches towards nitrogen- and phosphorus-efficient rice
Vinod KK, Heuer S (2012). Approaches towards nitrogen- and phosphorus-efficient rice. AoB PLANTS 2012: pls028; (DOI:10.1093/aobpla/pls028).
For thedevelopment of nutrient-efficient rice,a holistic approach should be followed combining optimized fertilizer management with enhanced nutrient uptake via a vigorous root system, leading to increased grain filling and yield. Despite an increasing number of N- and P-related genes and QTLs being reported, very feware actively used inmolecular breeding programmes. The complex regulation of N- and P-related pathways challenges breeders and the research community to identify large-effect genes/QTLs. For this it will be important to focus more on the analysis of tolerant genotypes rather than model plants, since tolerance pathways may employ a different set of genes.

Assessment of groundnut under combined heat and drought stress
Hamidou F, Halilou O & Vadez V (2013). Assessment of groundnut under combined heat and drought stress. Journal of Agronomy and Crop Science. Pubished online. (DOI:10.1111/j.1439-037X.2012.00518.x). Also printed in 2013.
In semi-arid regions, particularly in the Sahel, water and high-temperature stress are serious constraints for groundnut production. Understanding of combined effects of heat and drought on physiological traits, yield and its attributes is of special significance for improving groundnut productivity. Two hundred and sixty-eight groundnut genotypes were evaluated in four trials under both intermittent drought and fully irrigated conditions, two of the trial being exposed to moderate temperature, while the two other trials were exposed to high temperature. The objectives were to analyse the component of the genetic variance and their interactions with water treatment, year and environment (temperature) for agronomic characteristics, to select genotypes with high pod yield under hot- and moderate-temperature conditions, or both, and to identify traits conferring heat and/or drought tolerance.

Zhang J, Sun M, Zhang D, Li Y, Yan J, Shen S (2012). Breeding of Chang 8744, a new wheat variety of drought resistance, stable high yield and wide adaptability. Journal of Shanxi Agricultural Sciences 40(6):596–598, 623. (DOI: 10.3969/j.issn.1002-2481.2012.06.09). (G7010.02.01). Article in Chinese with abstract in English. Not open access: view online
According to additive inheritance and supplementary principle of parental traits, we took Jinmai 62 as female parent to hybrid with 98- 6160 as male. In the early generation, we selected the materials by planting in dry or irrigated land alternatively. In the high- generation, we evaluated the materials by measuring yield, selecting wheat spikes, surveying the agronomic traits in field and investigating the seed traits indoor. All above methods made the useful genes from parents expressed in Chang 8744 as drought resistance plus high yield, wide adaptability plus stable yield variety and super comprehensive agronomic performances.

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.

Can genomics boost productivity of orphan crops?
Varshney RK, Ribaut J-M , Buckler ES, Tuberosa R, Rafalski JA and Langridge P (2012). Can genomics boost productivity of orphan crops? Nature Biotechnology 30:1172–1176. (DOI: 10.1038/nbt.2440).
Advances in genomics over the past 20 years have enhanced the precision and efficiency of breeding programsin many temperate cereal crops. One of the first applications of genomics-assisted breeding has been the introgression of loci for resistance to biotic stresses or major quantitative trait loci (QTLs) for tolerance to abiotic stresses into elite genotypes through marker-assisted backcrossing (MABC)4. For instance, introgression of a major QTL for submergence tolerance (Sub1) into widely grown rice varieties has substantially improved yield in >15 million hectares of rain-fed low-land rice in South and Southeast Asia5. Despite this success story, the overall adoption of genomics-assisted breeding in developing countries is still limited especially for complex traits like yield under environmental stress in several other crops.

Construction of chromosome segment substitution lines in peanut (Arachis hypogaea L.) using a wild synthetic and QTL mapping for plant morphology
Foncéka D, Tossim H-A, Rivallan R, Vignes H, Lacut E, De Bellis F, Faye I, Ndoye O, Leal-Bertioli SCM, Valls JFM, de Bellis F, Faye I, Ndoye O, Leal-Bertioli SCM, Valls JFM, Bertioli DJ, Glaszmann J-C, Courtois B, Rami J-F* (2012).

Chromosome segment substitution lines (CSSLs) are powerful QTL mapping populations that have been used to elucidate the molecular basis of interesting traits of wild species. Cultivated peanut is an allotetraploid with limited genetic diversity. Capturing the genetic diversity from peanut wild relatives is an important objective in many peanut breeding programs. In this study, we used a marker-assisted backcrossing strategy to produce a population of 122 CSSLs from the cross between the wild synthetic allotetraploid (A. ipae¨nsis6A. duranensis)4x and the cultivated Fleur11 variety.
