Chai Y, Li X, Zhao Z, Sun L, Li Y and Jing L (2013). Diversity analysis of agronomic and quality characters of foreign wheat germplasm resources. Journal of Agriculture 3(9):1–8. Article in Chinese with abstract in English. (G7010.02.01)
Abstract: In order to gain knowledge of genetic diversity of wheat and improve their usage efficiency as germplasm resource. Diversities of agronomic and quality characters were analyzed for 146 foreign wheat germplasm in the field in southern Shanxi Province, basing on the data statistic analysis, principal component and cluster analysis methods. The average coefficient of variance was 10.9%, and the average diversity index was 1.4 with 18 wheat characters. It was-to seed yield, spike length, kernels per spike, spikes per plant, 1000-grain weight, stability time, tensile area, maximum resistance, sedimentation value and development time. Principal component and cluster analysis were used to 31 high-yield germplasm resources. The additive contributing rate of first eight principal components was 92.73%, eight major discriminating characteristics were selected to reflect the comprehensive economic characters and quality characters. According to the genetic distance, 31 germplasm resources were divided into 7 groups. Each group had different characteristics and showed abundant genetic diversity in agronomic and quality characters.

Association studies and legume synteny reveal haplotypes determining seed size in Vigna unguiculata
Lucas MR, Huynh B-L, da Silva Vinholes P, Cisse N, Drabo I, Ehlers JD, Roberts PA and Close TJ (2013). Association studies and legume synteny reveal haplotypes determining seed size in Vigna unguiculata. Frontiers in Plant Science 4:95. (DOI: 10.3389/fpls.2013.00095). (G6010.02/ G7010.07).
Highly specific seed market classes for cowpea and other grain legumes exist because grain is most commonly cooked and consumed whole. Size, shape, color, and texture are critical features of these market classes and breeders target development of cultivars for market acceptance. Resistance to biotic and abiotic stresses that are absent from elite breeding material are often introgressed through crosses to landraces or wild relatives. When crosses are made between parents with different grain quality characteristics, recovery of progeny with acceptable or enhanced grain quality is problematic. Thus genetic markers for grain quality traits can help in pyramiding genes needed for specific market classes.

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 199(1):1–11. (DOI:10.1111/j.1439-037X.2012.00518.x). Also published online in 2012.
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.

A survey of genes involved in Arachis stenosperma resistance to Meloidogyne arenaria race 1
Morgante CV, Brasileiro ACM, Roberts PA, Guimaraes LA, Araujo ACG, Fonseca LN, Leal-Bertioli SCM, Bertioli DJ and Guimaraes PM (2013). A survey of genes involved in Arachis stenosperma resistance to Meloidogyne arenaria race 1. Functional Plant Biology 40(12):1298–1309 (DOI: 10.1071/FP13096). (G6010.01)
Abstract: Root-knot nematodes constitute a constraint for important crops, including peanut (Arachis hypogaea L.). Resistance to Meloidogyne arenaria has been identified in the peanut wild relative Arachis stenosperma Krapov. & W. C. Greg., in which the induction of feeding sites by the nematode was inhibited by an early hypersensitive response (HR). Here, the transcription expression profiles of 19 genes selected from Arachis species were analysed using quantitative reverse transcription–polymerase chain reaction (qRT-PCR), during the early phases of an A. stenosperma–M. arenaria interaction. Sixteen genes were significantly differentially expressed in infected and non-infected roots, in at least one of the time points analysed: 3, 6, and 9 days after inoculation. These genes are involved in the HR and production of secondary metabolites related to pathogen defence. Seven genes encoding a resistance protein MG13, a helix-loop helix protein, an ubiquitin protein ligase, a patatin-like protein, a catalase, a DUF538 protein, and a resveratrol synthase, were differentially expressed in all time points analysed. Transcripts of two genes had their spatial and temporal distributions analysed by in situ hybridisation that validated qRT-PCR data. The identification of candidate resistance genes involved in wild peanut resistance to Meloidogyne can provide additional resources for peanut breeding and transgenic approaches.
