Relative Agronomic performance of different Dioscorea species found in different parts of Orissa.
Kambaska Kumar Behera , Santilata Sahoo and Aratibala Prusti
ABSTRACT: A study was under taken to quantify the relative agronomic performance of twelve Dioscorea species (11 wild and one cultivated species D.esculenta) found in different parts of Orissa .Various agro morphological character starting from plant height to yield per plant was evaluated among the twelve different Dioscorea species and presented in tabular form as per the standard agro metric method.The agronomic character analysis revealed that plant height was significantly superior in D. hispida (3.21 m) followed by the shortest height was noticed in D. oppositifolia (1.98 m). However at final stage of the crop highest number of leaves are found in D. oppositifolia (179) and D. wallichii (156). Tuber number per plant was the highest in D. esculenta (6.2) and there was only one tuber in D. bulbifera. The tuber: shoot ratio was significantly the highest in D. wallichii (2.43) and the lowest in D. oppositifolie (0.833). The ratio was very low in D. bulbifera and D. hamiltonii .The yield (kg/plant) was significantly highest in D. bulbifera (1.646 kg) and lowest yield was obtained with D. belophylla (0.654 kg) followed by D. Pubera (0.678 kg). From the study it is concluded that each species has their own identical agronomic character with certain similarities and dissimilarities among themselves.

Biochemical Quantification of protein , Fat, Starch, Crude fibre, Ash and Dry matter content in
different Collection of Greater Yam (Dioscorea alata L.) found in Orissa
Kambaska Kumar Behera, Trinanth Maharana , Santilata Sahoo and Aratibala Prusti
Abstract
A study was under taken to quantify the biochemical composition of protein, fat, starch, crude fiber, ash and dry matter in 22 different collections (C1 to C22) of Dioscorea alata fresh tubers. In the present study C-18 was found with highest dry matter (33.33%) where as lowest in C-3 (24.91%). The Average dry matter was highest in intermediate shape groups and collections with white flesh tubers. Starch percentage is highest in C-20 (82.51%) followed by C-1, C-7, C-3, C-22 and lowest is estimated in C-15 (78.36%). The highest protein content in dry matter of tuber was observed with C-1 (9.67%) and the lowest protein content was observed with C-13 (7.31%). The lowest fat content, however, was observed in C-11 (0.67%) and highest value was with C-2 (1.24%). C-1 had the lowest ash content of 1.89 % whereas C-15 had the highest value of 7.08 %. However, the ash content was towards the higher side in the intermediate group (5.85%). The crude fiber range was higher in the intermediate group i.e. out of five collections four were having more than 2% crude fiber. From the present investigation it is concluded that different collections of D. alata vary greatly for their dry matter, starch, protein, fat, ash and crude fiber content depending on different collection groups and the geographical regions.

Micropropagation of Greater Yam (Dioscorea alata L.
cv. Hatikhujia) Through Vine Nodes
Kambaska Kumar Behera, Santilata Sahoo and Aratibala Prusti
Abstract
Nodal segments of vines from the field grown plants of Dioscorea alata L. (cv. Hatikhujia) were cultured on Murashige and Skoog’s basal medium supplemented with different concentrations and combinations of BAP and Kinetin (Kn) along with NAA. Explants cultured in MS basal medium supplemented with 2.0 mg-l Kn +1.0 mg-l BAP + 0.5 mg-l NAA showed the best response to shoot multiplication. When in vitro shoots were inoculated on to the half-strength MS basal media supplemented with 2.0 mg-l NAA, rooting was more profuse. Rooted shoots were transplanted in the green house for hardening and their survival was 90% under field conditions with average yield of 0.612 Kg of tuber per plant.

Abstract
The present investigation was carried out with a view to regenerate plantlet of Dioscorea oppositifolia L through in vitro culture. Nodal vine segments from 45days old plants of field grown Dioscorea opositifolia were used as explants for initial culture. The explants were cultured on MS (Murashige and Skoog’s, 1962) medium supplemented with different concentration and combination of cytokinines and auxines for primary shoot proliferation. The best shoot proliferation was observed in MS medium containing 2.0 mg-l KINETIN +1.0 mg-l BAP+0.5mg-l NAA + 100mg-l ascorbic acid where 90 % of explants showed proliferation with highest rate of shoot multiplication (10.5 shoots per explant). For rooting, the in vitro micro shootlets were inoculated on to the half-strength MS basal media supplemented with 2.0 mg/l NAA and rooting was more profuse with micro tubers in the base of the root primordia. Rooted shoots were transplanted in the green house for hardening and their survival rate was 90 % in the field condition.

Response of Vine Cuttings to Rooting in Different Months in Three
Dioscorea species
Kambaska Kumar Behera, Santilata Sahoo, Trinanth Maharana, and Debashrita Pani
Abstract: Availability period of vine cuttings of different Dioscoreas in the field reveals that Dioscorea alata L. can be maintained throughout the year for collection of vine cuttings. On the other hand vine cuttings of D. oppositifolia L., can be collected from June to December and D. hispida Dennst., can provide cuttings from June to October. Earlier or latter to this no cuttings will be available. Each vine cutting should have one or two nodes. One of the nodes should be in soil. One leaf must be there in each cutting. Since the leaf is responsible for photosynthesis and transpiration the area of the leaf may be kept in a comfortable size by trimming to maintain a balance between
transpiration, photosynthesis and respiration.

Study of wild edible plants among tribal groups of Simlipal Biosphere Reserve
Forest, Odisha, India; with special reference to Dioscorea species
Sanjeet Kumar, Padan Kumar Jena, Prakash Kumar Tripathy
Abstract
The present study documented first time some of the most preferred wild food sources among the tribes Mankirdia, Kharia, Kolha, Santhal and others inhabiting in Simlipal Biosphere Reserve Forest, Odisha, India, particularly highlighting the importance of Dioscorea species. A total of 79 wild edible plants including 11 species of Dioscorea were assessed with respect to their availability, consumption pattern and harvesting. These foods are also stored by the tribal groups using different process for critical periods of food shortage and famine. The study emphasizes upon the need for exploring food resource available for wild plants and conservation of wide biodiversity of Odisha.
