Screening experimental designs for quantitative trait loci, association mapping, genotype-by environment interaction, and other investigations
Federer WT and Crossa J (2012). Screening experimental designs for quantitative trait loci, association mapping, genotype-by environment interaction, and other investigations. Frontiers in Plant Physiology 3:156. (DOI: 10.3389/fphys.2012.00156).
Crop breeding programs using conventional approaches, as well as new biotechnological tools, rely heavily on data resulting from the evaluation of genotypes in different environmentalconditions (agronomic practices, locations, and years). Statistical methods used for designing field and laboratory trials and for analyzing the data originating from those trials need to be accurate and efficient.The statistical analysis of multi-environment trails (MET)is useful for assessing genotype×environment interaction (GEI), mapping quantitative trait loci (QTLs), and studying QTL×environment interaction (QEI). Large populations are required for scientific study of QEI, and for determining the association between molecular markers and quantitative trait variability.

Exploring elite alleles for chlorophyll content of flag leaf in natural population of wheat association analysis
Li W, Zhang B, Zhang J, Chang X, Li R, Jing R (2012). Exploring elite alleles for chlorophyll content of flag leaf in natural population of wheat association analysis. Acta Agronomica Sinica 38(6):962–970. (DOI: 10.3724/SP.J.1006.2012.00962). (G7010.02.01). Article in Chinese with abstract in English. Not open access: view online
Elite alleles associated with chlorophyll content of flag leaf in a natural population of winter wheat (Triticum aestivum L.) consisting of 262 accessions were measured at flowering and grain-filling stages under both rainfed and well-watered conditions in two experimental locations in Beijing, China. A total of 169 SSR markers distributed on the 21 chromosomes of wheat were employed to detect the genetic diversity and genetic structure of the population. Association analysis between SSR loci and chlorophyll content trait was performed using TASSEL MLM (mixed linear model) program.

Phenotyping pearl millet for adaptation to drought
Vadez V, Hash T, Bidinger FR and Kholova J (2012). Phenotyping pearl millet for adaptation to drought. Frontiers in Plant Physiology 3:386. (DOI: 10.3389/fphys.2012.00386).
Pearl millet is highly resilient to some of the driest areas of the world, like the Sahel area or fringes of the Thar desert in India. Despite this, there is a wealth of variation in pearl millet genotypes for their adaptation to drought and the object of this paper was to review some related work in the past 25 years to harness these capacities toward the breeding of better adapted cultivars. Work on short duration cultivars has been a major effort. Pearl millet has also some development plasticity thanks to a high tillering ability, which allows compensating for possible drought-related failure of the main culm under intermittent drought. The development of molecular tools for breeding has made great progress in the last 10–15 years and markers, maps, EST libraries, BACs are now available and a number of quantitative trait loci (QTLs) for different traits, including drought, have been identified. Most of the work on drought has focused on the drought tolerance index (DTI), an index that reflect the genetic differences in drought adaptation that are independent of flowering time and yield potential.

Gene expression profile of wheat seedling response to drought stress by cDNA-AFLP
Zhang Y, Li J, Wang Z, Fan Z, Wang H, Zhang H (2012). Gene expression profile of wheat seedling response to drought stress by cDNA-AFLP. Journal of Triticeae Crops 32(2):240–244. (G7010.02.01). Article in Chinese with abstract in English. Not open access: view online
Drought is one of the most adverse environmental factors affecting wheat yield and quality. Under drought stress, target genes in wheat could be activated and expressed to produce drought-induced proteins, enabling plants to actively adapt to drought, and to maintain survival and yield formation. So, studying on drought-induced proteins and the related genes is essential for future genetic engineering and crop breeding of drought-resisting and water-saving. The objective of this research is to analyse the gene expression profile of wheat under drought stress, and to detect the fragments related to drought-resistant gene expression. Genes induced by drought stress in the seedling of Xinjiang spring wheat cultivar Xinchun 6 at 2-leaf stage were analysed by cDNA-AFLP techniques.

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.
