Phenotypic plasticity is a common and highly adaptive phenomenon where the same genotype produces different phenotypes in response to environmental cues. Sogatella furcifera, a migratory pest of rice exhibits wing dimorphism, is a model insect for studying phenotypic plasticity of wing size.

Drought-tolerance ensures a crop to maintain life activities and protect cell from damages under dehydration. It refers to diverse mechanisms temporally activated when the crop adapts to drought. However, knowledge about the temporal dynamics of rice transcriptome under drought is limited.

Abscisic acid (ABA) and proline play important roles in rice acclimation to different stress conditions. To study whether cross-talk exists between ABA and proline, their roles in rice acclimation to hypoxia, rice growth, root oxidative damage and endogenous ABA and proline accumulation were investigated in two different rice genotypes (‘Nipponbare’ (Nip) and ‘Upland 502’ (U502)).

A field experiment was conducted in kharif season of 2015 to investigate the influence of silicon solublizer on different rice genotypes namely PA-6129, PA-6201, PA-6444, PHB71, US-312, and BPT-5204. Soil application of silicon solubilizers was given at the time of maximum tillering, panicle initiation and 50% flowering stage. The experiment was arranged as split plot design with three treatments and three replications.

Weather and climate greatly influence the agricultural productivity in any region. Agricultural production and productivity of any region is regulated by the prevailing climate of that area through temperature, rainfall, light intensity, radiation, sunshine duration etc. The present experiment was carried to understand the influence of different growing environments and genotypes on heat unit requirement, heat use efficiency (HUE) and radiation use efficiency (RUE) in rice at the Instructional cum research Farm, IGKV, Raipur (C.G.) during Kharif-2013.

The experiment was laid out in a randomized block design with five replications in earthen pots with four different weedy rice genotypes viz. O. rufipogon, O. nivara, O. barthii and O. minuta. Data were subjected to analysis of variance using MS-Excel worksheet. Different morphological and growth behaviors characters and yield parameters were recorded for the morphological study of the different species.

A field screening of thirty four drought tolerant rice genotypes was conducted during Kharif 2017 and Kharif 2018 with the objective to identify different genotypes under drought stress condition. Significant variation was observed among genotypes for all studied traits including leaf rolling, leaf drying and relative water content.

The present study was carried out in sixteen genotypes having different aptitude for tolerance to stress. Drought stress was imposed at early reproductive phase of growth. Despites of reduction in plant height and number of tillers, genotypes have shown least reduction in the grain yield under drought stress.

The present investigation was under taken during rabi 2014-15 under rice fallow condition at District Seed Farm Kalyani, BCKV, W.B. Fifteen elite genotypes of chickpea (3 kabuli and 12 desi) were taken to evaluate and select the better yielding genotype(s) based on the nodulation behavior as well as root morphology, suitable for new alluvial zone of West Bengal and also to estimate the correlation among different underground and above ground agromorphic traits including yield.

Sixty four landraces were evaluated for 10 yield and its component traits. Analysis of variance showed significant difference among the genotypes to all the characters under both control and low-moisture stress condition. Environmental influence was meagre on expression of characters as evidenced by narrow gap between GCV and PCV for most of the characters.

Iron and zinc are essential micronutrients for both plant productivity and nutritional quality. Although Fe is the most abundant transitional metal in the world, its chemical properties hinder its availability to plants. The research aimed to compare different genotypes of aerobic rice for their iron and zinc content and measures their comparative losses among different genotypes, from brown to white rice. Quantification of Fe and Zn was estimated by using X-Ray Fluorescence Spectroscopy in brown and white rice.

The present study was conducted to evaluate the effect of phosphorus deficiency stress on root traits of diverse rice genotypes. Roots of rice genotypes grown in root rhizotron having soil P (P2O5 ≤ 7.59kg/ha), with and without P supplementation were compared for difference in total root length, lateral branching, surface area and volume.

Cereals are generally regarded as the “staff of life”. Wheat, rice and maize are the major cereals constituting the staple diet of the majority of the world population among which wheat is counted among the „big three‟ cereal crops. Zero tillage enables farmers to sow wheat in left optimum moisture with good germination capacity and increases soil aggregates due to minimal disturbance of soil structure/texture. The present experiment was conducted during rabi season of 2016-17 at agronomy farm of BAU, Sabour, Bihar.

Rice is the major food of more than 3 billion people representing the major carbohydrate and even protein source not only in South East Asia but also in some part of Africa .During the thousands of years since its domestication, Asia rice has been cultivated under significantly diverse agro-ecosystems to meet different human demands. As a consequence, many rice varieties with different characteristics have arisen under natural and human selection. In bastar plateau regions several land races of red rice are available which is having good yield potential.

The present study was conducted at the experimental farm of ICAR Research Complex for Eastern Region, Patna, India in Kharif season 2016 with an objective to identify sheath blight and bacterial leaf blight disease resistance rice genotypes under submergence condition in middle Indo Gangetic Plain. The disease incidence was observed at maturity stages during Kharif season 2016. The incidence of sheath blight and bacterial leaf blight of paddy ranged from 18.6 to 39.0% and 15.3 to 34.0%, respectively.

Drought is a major constraint in rice- growing areas of Asia. Identification of genomic regions containing QTLs governing drought tolerance traits is inevitable for developing novel genotypes with enhanced drought tolerance. A RIL population of 122 lines derived from a cross of Daggaddeshi/Danteswari was used for identification of QTL governing traits associated with yield was used in the study. A new QTL (qDTY12.2) linked to grain yield was identified in both stress and non-stress conditions.
