Managing Genetic Resources in Temperate Fruit Crops

Abstract

Biodiversity representing variation within genetic resources at gene, population, species and ecosystem level is our heritage that makes a key contribution to well-being and sustainable development. India is one of the mega biodiversity-rich countries of the world, with only 2.4% of the land area; it accounts for 7.8% of all the recorded species on this planet and ranks 10 th in the world and 4 th in Asia in plant diversity. This richness of species and genetic diversity provides many opportunities, which can be achieved through appropriate management of this diversity. There has been a significant progress in introduction, collection, characterization, conservation and utilization of genetic resources of horticultural crops. Germplasm management activities on temperate fruit in India are primarily carried out by NBPGR, however conservation in field gene banks is also done by various institutes. Besides field gene banks, germplasm of temperate fruits is also conserved by cryobanks, in vitro tissue culture. Thus, in the situation of climate change and depletion of natural resources, the challenges are more to feed growing population, so efforts are required for exploring the unexplored areas for collection of horticultural biodiversity for conservation and utilization for the benefit of mankind. In the quest to meet the emerging challenges, the gains with respect to genetic resources have to be sustained and further collection of new genes are required to be looked and utilized for gains where the strong base of horticultural plant biodiversity have to be in driving seat for bringing gene revolution.

Gall bladder Wall Thickness as Non-invasive Predictor of Oesophageal Varices in Cirrhotic Patients

“…In agreement with our results, Esmat et al [22] showed that the platelet/spleen diameter at a cut-off point of 1326.6 can predict OV with 96.3% sensitivity, 83.3% specificity, 96.3% PPV, and 83.3% NPV. In comparison to the current results, Qamar et al [23] and Hassan,et al [24] found that platelets/splenic longitudinal diameter (PLT/SLD) ratio did not revealed a significant difference in patients with and without OV, suggesting that these method cannot be used in the prediction of the presence of varices. This conflict may be attributed to differences in the severity of liver disease in our patients as 60 % of group II cases in our study were Child B &C and 90% of group I were Child A, despite the previous studies included patients with Child "A" and early "B" liver cirrhosis who had less impairment of platelet.…”

Blood Ammonia level : Is it a Clue for the Presence of Oesophageal Varices in Cirrhotic Patients ?

“…In the current study and according to the multivariate logistic regression analysis for predictors of OV, BAL was the only predictor of OV presence. This result was in agreement with Hassan,et al [19], who reported that BAL, PVD, SVD and SLD were good non-invasive predictors for the presence of OV in cirrhotics with the superiority of ammonia and PVD, and was in disagreement with Ramzy et al [16].…”

Genetic Stability Assessment of Six Cryopreserved Strawberry (Fragaria × ananassa Duch.) Accessions by Phenotypic and Molecular Studies

“…Recent progress in cryopreservation technology has demonstrated the safe, efficient, and economical advantages of long-term preservation. Therefore, the technology has undergone significant development during the last two decades, enabling the cryobanking of many crops such as apple, apricot, banana, blueberry, and garlic [ 8 , 9 , 10 , 11 ]. The cryopreservation protocols for strawberry have been developed using different methods [ 12 , 13 , 14 , 15 , 16 ].…”
