An experiment was conducted to examine the magnitude of genetic diversity and characters contributing to genetic diversity among 35 core elite wheat germplasm from INDIA and CIMMYT under water deficit condition. Principal components (PC) analysis showed that three components explained 67.73 per cent of the total variation among traits. The first PC contribute 38.8 per cent, second PC contribute 17.17 per cent and third PC contribute 11.66 per cent of total variation between traits. The first PC was more related to LSR, DSI, SCMR, RWC, ear weight per plant, harvest index and grain yield. The second PC was more related to plant height, LSR, tillers per plant, biological yield, thousand kernel weight and RWC. Therefore, selection based on first component is helpful for a good hybridization breeding program. Genetic divergence was carried out and grouped genotypes into six genetically distinct clusters. Cluster II genotypes viz., CHIRYA7, HW2041 and PBW502 shows superiority for functional stay green trait by exhibiting low cluster mean for leaf and DSI, and high cluster mean for SCMR, photosynthetic rate, RWC, tillers per plant, ear weight, 1000 kernel weight, biological yield, harvest Index, grain yield per plant and in contrast Cluster IV genotypes are non-stay green and drought susceptible by exhibiting high cluster mean for LSR and DSI. A three dimensional (3D Plot) depicts maximum genetic divergence between HW2041 and CBW38 and CHIRYA7 and HW2033. Stay green trait and all yield attributing traits except plant height can be improved by intermating HW2041 with CBW38 and CHIRYA7 with HW2033 genotypes which result in a highly heterotic hybrid for these traits under water deficit stress in wheat.Keywords

A registered product biozyme is extracted from a Norwegian Sea weed known as Ascophyllum nodosum. It is biodegradable and non-toxic for the plant and soil health as claimed by Biostadt company. Beside biozyme, several other zymes are also available in the market with some prefixes in the name. They claim, the zyme is toxin free, eco-friendly, bio degradable product containing growth hormones, elements, minerals and vitamins. Highly compatible with fertilizers and pesticides, it also increases the resistance of plants against various pests, diseases and climatic stress. These zymes are available in solid and liquid form and are being used as either top dressing or spraying on the crop canopy at important crop growth stages. As per some earlier studies, biozyme have claimed to have beneficial in crop growth both in vegetative part as well as in grain production. Keeping in view of its importance a field trial was formulated and being conducted in research farm of Bihar Agricultural University Bhagalpur (Bihar) to see the impact of Biozyme on the yield and soil microbes.Keywords

The present investigation is concerned with effects of distinct conductive and thermodynamic temperatures on reflection and transmission cofficients at an interface of two different micropolar viscothermoelastic solid half spaces. Reflection and transmission phenomenon of plane waves impinging obliquely at a plane interface between two different micropolar viscothermoelastic solid half spaces with two temperatures are investigated in the context of Green-Lindsay (G-L) theory (1972). The incident wave is assumed to be striking at the plane interface after propagating through one of the micropolar viscothermoelastic solid with two temperatures. Amplitude ratios of the various reflected and transmitted waves are obtained in closed form and it is found that these are function of angle of incidence, frequency and are affected by the micropolar, viscoelastic properties of the media. Viscosity effects are shown on these amplitude ratios for a specific model. Results of some earlier workers have also been deduced from the present investigation.Keywords
