Analysis of phenotypic data for 20 drought tolerance traits in 1–7 seasons at 1–5 locations together with genetic mapping data for two mapping populations provided 9 QTL clusters of which one present on CaLG04 has a high potential to enhance drought tolerance in chickpea improvement. Chickpea (Cicer arietinum L.) is the second most important grain legume(More)
Wireless sensor networks (WSNs) can be a valuable decision-support tool for farmers. This motivated our deployment of a WSN system to support rain-fed agriculture in India. We defined promising use cases and resolved technical challenges throughout a two-year deployment of our COMMON-Sense Net system, which provided farmers with environment data. However,(More)
Peanut is an important and nutritious agricultural commodity and a livelihood of many small-holder farmers in the semi-arid tropics (SAT) of world which are facing serious production threats. Integration of genomics tools with on-going genetic improvement approaches is expected to facilitate accelerated development of improved cultivars. Therefore,(More)
Wild Arachis genotypes were analysed for chlorophyll a fluorescence, carbon isotope discrimination (ΔC), specific leaf area (SLA), and SPAD readings. Associations between different traits, i.e., SLA and SPAD readings (r =–0.76), SLA and ΔC (r = 0.42), and ΔC and SPAD readings (r = 0.30) were established. The ratio of maximal quantum yield of PSII(More)
Developing trait introgressed rice cultivars is essential to sustain yield under aerobic conditions. Here, we report DNA markers governing variability in root traits, water use efficiency (WUE) and other biometric traits like total leaf area by association mapping. A set of 173 diverse rice germplasm accessions were phenotyped for root traits in specially(More)
Drought is a major restrictive factor for declining grain yield in lentil globally. Present investigation was conducted by taking microsperma (HUL-57) and macrosperma (IPL-406) genotypes of lentil (Lens culinaris Medik.) as information regarding physiological and biochemical basis of differences in drought resistance in macrosperma (bold-seeded) and(More)
The basic leucine zippers (bZIPs) are one of the largest families of transcription factors that have been demonstrated to play diverse roles in plant growth development. These proteins are known to regulate many cellular responses in plants under stress conditions. In this study, a stress-responsive transcription factor belonging to bZIP family was cloned(More)
Dendroclimatology can be a useful tool in assessing moisture stress tolerance in tree species that form distinct annual rings, especially in natural selection. This study is an attempt to demonstrate the use of dendroclimatology in assessing moisture stress response of teak. Genetic diversity of 48 teak clones was assessed using teak-specific microsatellite(More)
