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.

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.

Wang J, Mao X, Li R, Jing R (2012). Sequence polymorphism and mapping of wheat Ca2+-binding protein TaCRT-A gene. Chinese Journal of Applied Ecology 23(9):2536 –2542. (G7010.02.01). Article in Chinese with abstract in English. Not open access: view online

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.

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.

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.

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.

Assessment of groundnut under combined heat and drought stress 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.
