Phenotyping pearl millet for adaptation to drought 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.

An intra-specific consensus genetic map of pigeonpea [Cajanus cajan (L) Millspaugh] derived from six mapping population 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.

Phenotyping for drought tolerance of crops in the genomics era Phenotyping for drought tolerance of crops in the genomics era

Tuberosa R (2012). Phenotyping for drought tolerance of crops in the genomics era. Frontiers in Plant Physiology 3:347. (DOI: 10.3389/fphys.2012.00347).

Improving crops yield under water-limited conditions is the most daunting challenge faced by breeders. To this end, accurate, relevant phenotyping plays an increasingly pivotal role for the selection of drought-resilient genotypes and, more in general, for a meaningful dissection of the quantitative genetic landscape that underscores the adaptive response of crops to drought. A major and universally recognized obstacle to a more effective translation of the results produced by drought-related studies into improved cultivars is the difficulty in properly phenotyping in a high-throughput fashion in order to identify the quantitative trait loci that govern yield and related traits across different water regimes. This review provides basic principles and a broad set of references useful for the management of phenotyping practices for the study and genetic dissection of drought tolerance and, ultimately, for the release of drought-tolerant cultivars
