Breeding of Chang 8744, a new wheat variety of drought resistance, stable high yield and wide adaptability
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.

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.

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.

Analysis of constituents for phenotyping drought tolerance in crop improvement
Setter TL (2012). Analysis of constituents for phenotyping drought tolerance in crop improvement. Frontiers in Physiology 3:180. (DOI: 10.3389/fphys.2012.00180).
Investigators now have a wide range of analytical tools to use in measuring metabolites, proteins and transcripts in plant tissues. These tools have the potential to assist genetic studies that seek to phenotype genetic lines for heritable traits that contribute to drought tolerance. To be useful for crop breeding, hundreds or thousands of genetic lines must be assessed. This review considers the utility of assaying certain constituents with roles in drought tolerance for phenotyping genotypes. Abscisic acid (ABA), organic and inorganic osmolytes, compatible solutes, and late embryogenesis abundant proteins, are considered. Confounding effects that require appropriate tissue and timing specificity, and the need for high-throughput and analytical cost efficiency are discussed. With future advances in analytical methods and the value of analyzing constituents that provide information on the underlying mechanisms of drought tolerance, these approaches are expected to contribute to development crops with improved drought tolerance.

An intra-specific consensus genetic map of pigeonpea [Cajanus cajan (L) Millspaugh] derived from six mapping population
Bohra A, Saxena RK, Gnanesh BN, Saxena KB, Byregowda M, Rathore A, KaviKishor PB, Cook DR, Varshney RK (2012). An intra-specific consensus genetic map of pigeonpea [Cajanus cajan (L) Millspaugh] derived from six mapping populations. Theoretical and Applied Genetics 125(6):1325–1338. (DOI: 10.1007/s00122-012-1916-5).
Pigeonpea (Cajanus cajan L.) is an important food legume crop of rainfed agriculture. Owing to exposure of the crop to a number of biotic and abiotic stresses, the crop productivity has remained stagnant for almost last five decades at ca. 750 kg/ha. The availability of a cytoplasmic male sterility (CMS) system has facilitated the development and release of hybrids which are expected to enhance the productivity of pigeonpea. Recent advances in genomics and molecular breeding such as marker-assisted selection (MAS) offer the possibility to accelerate hybrid breeding. Molecular markers and genetic maps are pre-requisites for deploying MAS in breeding. However, in the case of pigeonpea, only one inter- and two intra-specific genetic maps are available so far. Here, four new intra-specific genetic maps comprising 59–140 simple sequence repeat (SSR) loci with map lengths ranging from 586.9 to 881.6 cM have been constructed.
