RESEARCH CHIEVEMENTS 4.1 ACHIEVEMENTS OF IX TH PLAN 4.1.1 Crop Improvement • Established the National active germplasm site for grapes at NRCG with 350 grape accessions. These were collected from various research institutes within the country and abroad. It includes disease resistant inter-specific crosses evolved in France, Australia, USA, Russia, Korea and Japan and indigenous grape varieties grown / evolved in India and related wild species from Himalaya and western ghats. • Seventeen rootstock varieties including 110R, 99R, SO4, 1103P, St. George, Salt Creek and 1613C were procured. • Characterization of germplasm by ampelography was initiated and reported. Two phenotypes of Dogridge rootstock were distinguished by ampelometry. 4.1.2 Crop Production • Tas-A-Ganesh vines were found to be more vigorous on Dogridge B but bold berries and highest yield per vine was also recorded on Dogridge B. • Survey was undertaken in Sangli district of Maharashtra in order to find out the threshold level of salinity tolerance of Thompson Seedless on Dogridge rootstock and the collected data under the survey revealed that the levels of ESP, pH and Ca content in most of the vineyard soils was within the safe limit. • Performance of Thompson Seedless grafted on Dogridge B, Salt Creek, 1613 C and St. George to single level of imposed soil moisture stress in an existing vineyard, revealed that Thompson Seedless on Dogridge B performed well in terms of growth, yield and quality both under normal and stressed conditions. • In order to develop petiole nutrient guides for Thompson Seedless vines raised on Dogridge B rootstock, data with respect to petiole nutrient status at bud differentiation and full bloom stage, yield and quality parameters were recorded. 4
• Studies on bunch stem necrosis disorder in Sangli region showed that the necrosis was due to impaired translocation of Ca to the rachis and Mg deficiency. • Studies on leaf curl in grapes revealed that leaf curl was associated with potassium deficiency. • Application of Hydrogen cyanamide @ 1 - 1.5% at the time of pruning was found to induce early and uniform budbreak on grafted Thompson Seedless vines. This facilitated uniform cultural operations necessary for improving the quality of grapes. Continuous use of hydrogen cyanamide did not result in deleterious effects on vine growth, productivity and quality of fruits. • A plant bio-stimulant, N-Acetyl Thiazolidine-4-Carboxylic Acid (Quantum) at 0.05% as spray at 45 and 75 days after fruit pruning and dip at 102 and 110 days after pruning was found to have potential to increase total chlorophyll content, bunch weight, berry length and berry crispness. • Use of COMBINE - a homobrassinolide based plant bio-stimulant, @ 1 ppm in combination with Gibberellic Acid (GA3) or 4 Chloro 2 Pyridil N Phenyl Urea (CPPU), increased berry weight, improved berry size and increased the shelf life of grapes. • Addition of a GA 3 adjuvent - VININ @ 5 ml per litre with GA3 increased the efficacy of GA 3 in producing loose clusters, improved berry weight and berry size and increased the pedicel thickness which is prerequisite for longer shelf life. • The efficacy of Gibberellic acid for producing loose bunches and increasing berry size, was enhanced by the use of ethyl oleate @ 100 g / litre along with GA 3 , thus minimizing the post-harvest losses due to desiccation in storage. 4.1.3 Crop Protection • Studies on fungi associated with post harvest decay in table grapes meant for overseas markets indicated that during storage at 0 0.5 0C, post harvest decay was minimal and caused due to Alternaria alternata and Cladosporium sphaerospermum. Infection of both these fungi was restricted to individual berries. On shelf, Aspergillus spp. mainly A. niger, Botryodiplodia theobromae, and Penicillium spp. were found associated with decayed berries, while Rhizopus stolonifer was associated with bunch rot. Botrytis cinerea and Phomopsis were not detected in any sample. • Irregular cane maturity due to the fungus Botryodiplodia was identified as a serious problem in vineyards of different varieties of all ages all over India. The fungus is thought to be spreading through infected planting material. A simple procedure based on incubation in sterilized polythene bags was developed for large-scale detection of Botryodiplodia infection in vine. • The use of citric acid in water for its acidification, before preparing pesticide solutions, improved the pesticide efficacy. • Varietal reaction to mealybugs revealed that out of 11 varieties tested, incidence was negligible in Bangalore Blue and Bangalore Purple, moderate in Cardinal, ARI-H-144, Beauty Seedless, Sonaka, Sharad Seedless and Pusa Urvashi. Highest susceptibility was recorded in Thompson Seedless and Arkavati. • The terminal residues of hydrogen cyanamide in grape berries were monitored for three 5
