Abstract: On 18th April 2013, the Commision on Genetic Resources for Food and Agriculture (CGRFA) of the United Nations Food and Agriculture organization (FAO), endorsed and adopted the revision of Genebank Standards, last published in 1994. These Standards are meant to ensure that plant genetic resources for food and agriculture (PGRFA) are conserved in genebanks under recognized and appropriate conditions, based on current technological and scientific knowledge. Simply defined, genebanks are places where either seeds are conserved at low temperature and moisture, or whole plants/plants propagules are conserved in field or culture vessels or in cryovials. Genebanks exist throughout the world and they collect, catalogue, store and protect as many species of plants and genepool of crops as possible, so that it can be drawn appropriatly for use. They are usefull to plant breeders involved in research and/or breeding for developping new climate-resilient varieties, to respond to growing environmental pressures and to feed a rapidly expanding population. They can also provide a resource for restoration of key species after natural or man-made catastrophes.

Abstract: North East (NE) India, commonly known as the ' land of seven sisters ' is a territory of diverse ethnic groups, tribes and culture. Shifting cultivation, locally known as ' jhum ' or ' jhumming ' , is a way of life for many of these tribes since time immemorial. The percentage utilization of cultivable area in this region (62.04) is less than the national average (73.05).
It has been reported that about 80% of the farmers in the region are small (<1.44 ha) and marginal (<0.40 ha) land holders. In most of the hilly states of NE India, The forest lands are becoming baren due to the practice of jhum cultivation. About 19% of the total area uder the shifting cultivation in the hills accounts for 0.76 m ha (current jhum - 0.39m ha and abandoned jhum -0.36 m ha)? that support 4.43 lakhs famillies for their livelihood. The jhum system as practised earlier with a follow period of 10-15 years appeared to be sustainable. However, it has significantly reduced to 1-3 year in present situation, which has made the land vulnerable to ecological degradation and resulted into limited production. Considering the present practice of cultivation in this region, it is the need of the hour to improve the jhum lands by adopting suitable soil and water conservation measures, viz. bench terracing, contour binding, contour trenching, half moon terrace, catch pits, hedge rows, agroforestry, etc. Introduction of the fast growing trees with multiple uses is one of the viable options for conserving valuable resources as well as to uplift the socio-economic status of the jhumias.

Abstract: As in previous years, India Meteorological Department (IMD) has issued a press release that the June-September monsoon rainfall for the country as a whole, i.e. the all-India rainfall (AIRF) is expected to be about 98% of the long term average (LTA) of 89cm,
with an model error of ?5%. A week before this announcement a private agency a forecast that AIRF will be 103% of LTA with an error margin fo 4%. AIRF includes the whole of India made up four sub-regions: Central India (CEIND), North East India (NEIND), North West India (NWIND), and South Penninsular India (PEIND).
AIRF is naturally statistically correlated with some of the regional values, but the region among themselves are not all well correlated. Table 1 shows the basic statistics and Table 2 shows the correlation among the five data series of IMD. It is seen that the characterisation of AIRF is not a good reflection of what to expect in NEIND and PEIND

Abstract: There is growing interest in medicinal plant research worldwide. Plants and plant-derived products are widely used in the traditional system of medicine. Often herbal drugs are considered unsafe, found less effective and fail to meet the quality standards due to several reasons. Primary among them are: (i) insufficient expertise in plant identification and lack
of pharmacological knowledge; (ii) adulteration as a result of over exploitation of medicinal plants;(iii) variations in growing conditions;(iv) Genetic Variability and (v) diversity in harvesting methods and proccessing of extracts. It is therefore essential to establish internationally recognized guidelines for assesing their quality.

Abstract: District-wise and crop-wise status of lac growing districts of Madhya Pradesh have been assessed with parameters like minimum, maximum, average production and simple growth rate (SGR) for four years (2006-07 to 2009-10). The study reported that the state contributes 16 per cent production of the country; however, the growth rate during the study period was negative and to the tune of 10.1 per cent per annum. Seoni district contributed maximum in lac production (41.6 per cent) followed by Balaghat (30.6 per cent), Hosangabad (8.4 per cent) and Mandla (7.0 per cent). Strain-wise growth rate for the whole state showed taht both rangeeni and kusmi lac production attained a negative growth of 5.2 and 32.1 per cent per annum. Crop-wise growth rate for the state showed thet rangeeni-summer attained positive growth (12.1 per cent annum) while rangeeni-rainy registered negative growyh (37.5 per cent). Similarly, both kusmi-winter and kusmi-summer crop registered negative growth rate of 34.0 and 29.9 per cent annum respectively. Major reduction in lac production was due to loss of rangeeni-rainy crop which caused less availability of broodlac for next season. Thus less production in one season indirectly affected production of succeeding season crops also.

Keywords: Census, Magnoliophyta, Ayodhya Hill, Forest tribes
Abstract: The inventory of the Magnoliophyta (angiosperms) in the forest abodes of the tribes (Paharias, Birhors, Sardars and santhals) in Ayodhya hill shows the community to be composed of 132 species, of which 98 species are dicotyledonous and 16 monocotyledonous. At specific, generic, family and class level, dicots scored high percentages over monocots. The ratios of trees, shrubs, herbs and climbers associated with the forest abodes of tribes of Ayodhya Hill were found to be 44:31:38:19 respectively. Value of Jacard Generic Coefficient of the forest flora was 86.36 which speaks of appreciable texonomic potential to render stability to the ecosystem. This value is expected in course of time to be progressively reduced to 1. Since the difference between the observed and expected values of generic coefficents is low (13.64), there is a possibility of successful revegetation and restoration of the forests studied.

Ezperiments were conducted in order to investigate different temperatures and lenghts response index in germination behavior of H. salicifolia seeds. The highest mean germination was obtained at 25 degree C. Therefore, it is recommended that + and -25 degree C can be considered optimum temperature for its seed germination under controlled conditions. The light study revealed that maximum germination percentage was found in red light followed by yellow light and minimum germination observed in green light. Provenance of Chamoli was the best as compared to Uttarkashi and Pithoragarh

Abstract: Present study explored the diversity of soil oribatid in four different ecosystems Cachar district of Assam, during July, 2009. Oribatid microarthropod were dominant in homegarden (35.45%), whereas members of Trhypochthonidae were found to be higher in teak plantation (24.03%). Finding suggest that the members of oribatulidae family are most resistant survivor under different land used practices. Density of total cryptostigmatid mites showed decreased order from the undisturbed site to disturbed sites (forests>secondary succession>homegarden>teak plantation). Species similarity of oribatid mite associations in 4 study habitats found that maximum was (45.00%) between secondary succession and forest site and minimum between the teak plantation and homegarden (7.14%). Study consludes that oribatid mites could not be used as an absolute bioindicator of land types.

Abstract: The variations present in seed and pod traits, genetic superiority and genetic divergence were evaluated for a Seeding Seed Orchard (SSO) of Dalbergia sissoo Roxb, at Bithmera, India sonsisting of 19 progenies from the state of Uttarakhand. The seeds and pods of various progenies in the orchard exhibited significant variability in size, weight and other characters. Significant positive correlations were observed between seed length and weight (P<0.01), seed width and seed weight (P<0.01), seed thickness and seedseed weight (P<0.05), seed weight and germination value (P<0.05), seed lemgth and germination value (P<0.05). The genetic parameters for seed and pod traits also showed a wide range of variations. Hertiability values were found to be over 50 for most of the seed and pod traits, however, only seed weight showed high heritability values coupled with maximum genetic gain. Ward ' s minimum variance dendrogram of progenies of D. sissoo showed three distinct sluster 1 with 6 better progenies, cluster 2 with 10 moderate and cluster 3 with 3 poor progenies. Mean cluster values showed sufficient variation among the clusters for seed weight, germination value and seed length. The possibility of controlled hybridization between better progeny (288) of cluster 1 to the disease resistant progeny (304) of cluster 3 (resistant against deadly Gandoderma lucidum root rot disease of D. sissoo) is also suggested for durther breeding programmes of the species.
