Title: A Comprehensive and Brief Review on Appraisal of Cucumber Mosaic Virus Infecting Vegetable Crop Capsicum spp.
Abstract :

Capsicum is an important vegetable crop in most part of the world. Viral diseases are the most important diseases that cause huge losses to Capsicum. Many viruses infect Capsicum and sometimes, plants are infected by a combination of viruses. Among them Mosaic disease is one of the most important viral disease caused by Cucumber mosaic virus (CMV) of Capsicum worldwide. From the beginning of the discovery of CMV in Capsicum on 1960s, a number of reports published till date on the disease incidence, host range, diagnosis, pathogenicity, severity and losses due to infection, biological and molecular characterization, genome organization, several biological, cultural, biochemical and biotechnological approaches for disease management and even development of transgenic Capsicum resistant to this virus are mostly studied. Taking into consideration of the importance of this devastating virus causing great yield loss in Capsicum crop, there is an urgent need to thoroughly study about the trend of the infection and severity of CMV alone or in combination with other Chilli viruses in the host. In this brief review, most of the reports are basically focused on the disease incidence study in various geographical locations in the world along with detection techniques implied and possible management practices to control this disease in sustainable are also discussed.

Title: Diversity of Vegetable Crop in Home Gardens of Sub Himalayan Districts of West Bengal, India
Abstract :

Home gardens are the reservoir of diverse multipurpose annual and perennial plant species and act as important in situ conservation sites for agricultural and horticultural biodiversity. Climate of sub Himalayan districts of West Bengal is highly suitable for cultivation of different seasonal and perennial vegetables round the year. The region has the diverse plant species utilized for fresh vegetable and ethno medicinal use. Among individual crop, variability exists in plant morphology, flowering behavior, fruit shape, size, colour and seed characteristics etc. The rich diversity remains unexploited for crop improvement programme. To understand biodiversity pattern of vegetable crops under different home garden system, an exploration was carried out during 2011 and 2012 covering two districts namely Coochbehar and Jalpaiguri. Information was collected through questionnaire survey and field observation of selected households. The detailed investigation into the variability of different vegetable crops has been highlighted. The study revealed that the indigenous knowledge and belief of the farming community encourage growing diverse vegetable crops. But in the present system there is a need of proper documentation of the existing diversity so that it can be utilized for future crop improvement programme as well as for rural subsistence, livelihood security, heath benefits and conservation of biodiversity.

Title: Quality Improvement of Bael (Aegle marmelos Corr.) Candy and Storage Studies
Abstract :

The research was done with two cultivars of bael like Local cultivar of West Bengal and NB-5 with a large fruit size and having a greenish yellow to yellowish green colour, average fruit weight (723.50 and 1212.50 gram), pulp per cent (75.40 and 79.62), TSS (12.2 and 14.4 oBrix), ascorbic acid (13.12 and 27.36 mg/100 g pulp) and β-carotene (1868.01 and 1155.37 IU) were analyzed in the fresh fruits. The product of bael candy was prepared by using of sugar, acid, water and preservatives. The slices were dipped in different concentration of alum solution for two hours and blanched. The best recipe of bael candy was found 2 per cent alum concentration and the standardized processed product was stored at room (25 – 37 oC) and refrigerated temperatures (8 -10 oC) up to 8 and 12 months and with organoleptic score 4.66 and 4.94 was found best among all treatments of local and NB-5 cultivar respectively. The economic analysis of the standardized products revealed that the income per rupee investment of bael candy was Rs. 0.79 and Rs. 1.16 for local and NB-5 respectively.

Title: Analysis of Diversity of Scarlet Egg plant from Garo Hills of Meghalaya
Abstract :

Diverse genetic material to initiate plant breeding in scarlet egg plant (Solanum aethiopicum L.) is available but lacks in characterization and trait evaluation. Meghalaya provides a hotspot for biodiversity of Solanum aethioipcum L. This crop occurs widely but is not commercially grown in a wide range. Nine germplasm lines of scarlet egg plant were collected from different parts of Garo Hills of Meghalaya, India and were characterized based on four quantitative traits like fruit length, fruit breadth, fruit pedicel length and fruit weight. The diversity of this crop was analysed by statistical analysis using randomized block design. Highly significant differences were revealed among the selected germplasm lines indicating a wide variability of each trait studied.

Title: Correlation Studies of Carrot (Daucus carota L.) germplasms from Garo Hills of Meghalaya, India
Abstract :

Fifteen germplasm lines of carrot collected from different parts of Meghalaya, India were evaluated on the basis of 15 horticultural traits in a randomized block design with three replications at Krishi Vigyan Kendra, ICAR NEH, Sangsangiri, Tura, Meghalaya, India during winter season from October (2014) to January (2015). Correlation analysis was carried out to study the character association and contribution for ten quantitative characters, namely leaf length (cm), leaf width (cm), petiole length (cm) length(cm), root diameter (cm), days to root harvest, root weight (g) and yield (t/ha) for the identification of appropriate selection indices. Phenotypic and Genotypic correlation coefficient analysis revealed that root weight, days to root harvest, root length, leaf width, petiole length, leaf length and root diameter had significant positive correlation with marketable yield.

Title: Evaluation of Sweet Potato (Ipomoea batatas (L.) Lam.) Genoypes for Chhattisgarh Plains
Abstract :

Sweet potato (Ipomoea batatas (L.) Lam.) is an important tuber crop grown for its tender leaves and tuber as a vegetable in Chhattisgarh plains. The tuber and tender leaves of this crop are very nutritious and used for preparation of various vegetarian dishes. It is consumed as boiled, dried and preserved form. It is sixth most important tuber crop in the world with an annual production of 138.4 million tonnes from 9.2 million hectares with a productivity of 15.0 t/ha (Edison, 2002). In India, it covered an area of 0.14 million hectares producing 1.71 million tonnes tubers with a productivity of 8.3 t/ha (Anonymous, 2000). Chhattisgarh covered an area of 2041.8 hectares producing 10965.6 tonnes with a very low productivity of 5.3 t/ha (Patil, 2001). Farmers of this agro-climatic zone are generally cultivating local sweet potato genotypes which are poor yielder in general. Hence, an experiment was carried out to evaluate twenty four genotypes of sweet potato at Department of Horticulture, Indira Gandhi Agricultural University, Raipur, Chhattisgarh in randomized block design with three replications and observations were recorded on vine length (cm), vine weight (g), number of tuber, number of marketable tuber, neck length of tuber (cm), tuber diameter (cm), tuber length (cm), biological yield (kg), tuber yield (t/ha), marketable tuber yield (t/ha), harvest index (%), total soluble solids (%), dry matter percentage of foliage (%) and dry matter percentage of tuber (%). Replicated data for each character was statistically analyzed. Experimental findings showed that sweet potato genotypes viz., Shree Bhadra (47.17 t/ha), shree Rathna (46.14 th/ha) and IGSP-12 (42.84 t/ha) recorded maximum total tuber as well as marketable tuber yield. Whereas, total soluble solids was recorded highest (17.10%) in IB-90-15-9 (Indira Sakarkand-I) followed by IGSP-31 (14.50), IGSP-10 (14.26) and Pol-21-1 (14.10). Hence, these sweet potato genotypes may be suitable for Chhattisgarh plains.

Title: Correlation and Path Analysis in Sweet Potato
Abstract :

Sweet potato (Ipomoeo batatas (L.) Lam.) is an important tuber crop grown in Chhattisgarh for tuber and tender leaves which are nutritious and tuber is used for vegetable purpose as boiled and dried product. tuber yield is a complex characters which is dependent on various components. In sweet potato correlation coefficient among tuber yield .So the relative contribution of each component character to the tuber yield could be assured. Hence, the objective of the present investigation was to study the direct and indirect influence of some yield components on tuber yield in sweet potato. The present investigation was carried out during rabi 2002-03 in randomized block design replicated thrice along with twenty four genotypes of sweet potato. Observations were recorded on vine length (cm), vine weight (g), number of tubers, number of marketable tuber, neck length of tuber (cm), tuber length (cm), tuber diameter (cm), biological yield (kg), tuber yield (t/ha), marketable tuber yield (t/ha), harvest index(%), total soluble solids (%), dry matter percentage of foliage and tubers in sweet potato. Results revealed that significant and positive correlation coefficient was found between tuber yield with biological yield and tuber diameter. Correlation coefficient between harvest index was also found to be positive. Path coefficient analysis revealed that vine weight per plant and number of marketable tuber per plant were important traits influencing tuber yield and could be utilized as selection Criteria in sweet potato improvement program for Chhattisgarh plains.
