Several grape varieties are known to possess resistant genes against downy mildew. A cross between two seedless varieties often results into embryo abortion resulting in no progeny plants. It was  possible to rescue hybrid embryos as soon as they are formed but before their abortion and raise hybrid progeny. Several hybrid plants have been obtained having considerable resistance to diseases but mostly turned out be seeded. Further crossing with preferred seedless parents is necessary to bring about satisfactory introgression of the traits. Similarly improved rootstocks are required through breeding  for tolerance to  low /high soil moisture and high soil salinity. Thus it is possible to develop new grape varieties by  conventional breeding method and use of DNA molecular markers to ascertain hybrid progenies at seedling stage itself is the most recent and preferred approach worldwide.

 In India, grape cultivation is concentrated in the semi arid region. Unpredictable rains, poor irrigation water quality, excess use of fertilizers, intensive cultivation, poor farm management and poor drainage adds to the already prevalent saline soil conditions. Productivity is declining for past 10-15 years in major grape growing regions of the country due to problems associated with drought and soil and water salinity. The understanding of salinity stress will be greatly enhanced by elucidating the structural and regulatory genes responsible for developmental and physiological processes under stress response. Besides several structural genes, Transcription Factors (TFs) are the key molecular switches controlling key biological processes. The 12X genome sequence of the grape with the V0 version of the gene annotation is available in public domain. The sequence information can be used for searching the candidate genes using comparative genomics and prediction model approaches.

Of the four protocols compared for protein extraction, resolution of protein in 1st dimension and 2nd dimension gel was improved with modified trichloro acetic acid/acetone precipitation coupled with phenol extraction method. This method also yielded higher protein yield, greater spot resolution with minimal streaking on 2D gels. The same protocol could yield higher quality protein from other grape tissues such as buds, berries and roots. This protocol can give good quality protein with satisfactory and reproducible separation on 2D gels.

Among different stocks scion combinations, Thompson Seedless grafted on 110 R rootstocks and own rooted vines imparted maximum bud burst percentage after forward pruning which was attributed to increased peroxidase and polyphenol oxidase activity in their buds and also to highest protein content. Maximum bud fruitfulness was recorded on 110R rootstock and own rooted vine.

Analysis of hormones at different stages of berry development revealed definite trend. Endogenous IAA was highest during initial stages of berry development (1st two stages); while GA3 concentration was highest till 8-10 mm berry size (responsible for cell enlargement and ABA concentration was highest at Veraison stage and later on there was decrease in its concentration.

The technologies for quality wine grape production are still in the nascent stage in India. In fact systematic research is lacking in production technologies for wine grape cultivation. Cabernet Sauvignon is one of the wine varieties adapted to hot climate conditions. However, the cultivation practices being followed elsewhere are applied to our situation. This is not the right practice. Judicial application of water will not only help in maximizing the scarce water resource but at the same time also help in minimizing the salinity risk. Most of the vineyards in India are drip irrigated. The advantage of this irrigation technique lies in the precise control over time, quantity and desired area of water application. Amongst the various inputs applied to the crop, water is the most important input.

01.04.2008 to 31.03.2014

Persistence and dissipation of the residues of new generation pesticides will be explored. Residues will be monitored in grapes on a regular basis at different time intervals after final spraying till harvest. Dissipation rate kinetics will be studied to estimate half-life and pre-harvest interval (PHI) of pesticides in grapes on the basis of latest and minimum MRL available at international level. In case of older pesticides, PHI will be re-determined by conducting dissipation studies with regards to new MRL.

Twenty years before there was no Indian made wine was available with drinkable quality. All hot countries like India, Brazil, South Africa, Thailand etc. are relatively new to wine making and wines produced from tropical regions are known as new world wines. In the tropical regions like India, both local and old world wines are clearly extremely vulnerable to poor storage and transport conditions. The main constraint in achieving the quality goal in our country is fact that the quality compliances are very poor among the wine manufactures. In order to understand the export potential and improvement in domestic consumption of Indian wines it is of utmost importance to address quality related issues. The wine technology in India is transferred from temperate regions. The technical involvement for production of wine in India is adopted as such which developed in temperate regions. However, our grape production falls in tropical climatic conditions.  So we can’t follow the maturity indices as well as harvesting time, which is developed from temperate conditions. The harvesting of berry at proper maturity and harvesting time have prime role in the production of quality wine. The quality parameters of grape berries at harvesting time directly affect the quality attributes of wine such as alcohol percentage, acidity, aroma compounds etc.

Grapes are one of the most popular and palatable fruits in the world. The preservation of grapes by drying is a major industry in many parts of the world where grapes are grown. Drying practices vary with geographical locality and with the variety of grapes. Drying grapes, either by open sun drying, shade drying or mechanical drying, produces raisins. Air-drying of solar energy has been demonstrated to be cost-effective and could be an effective alternative to traditional and mechanical drying systems, especially in locations with good sunshine during the harvest season. The raisin colour is deciding factor for the price of processed produce. In world market, green coloured raisins catch more prices.  In India, mainly yellow or brown coloured raisins are being produced. Enzymatic and non-enzymatic activities are responsible for browning of raisins. High humidity at the time of grape dying (due to rains), content of polyphenols in berries, prevailing temperature, exposure to direct sunlight etc. are responsible factors for raisin browning. In the last grape drying season, Solapur and Sangli regions faced untimely heavy rains resulted in heavy loss of produce due to browning. During grape drying process, sulfur fumigation leads production of yellow coloured raisins.
