Objectives:
To study the inheritance of economically important traits
To develop viable alternate varieties suitable for table, raisin, juice and wine making.
To identify clonal selections of both natural and induced mutants with improved plant & fruit characters by molecular markers .
To develop tolerant grape varieties and rootstocks to biotic and abiotic stress
To develop marker assisted selections for economically important traits.
To develop right protected varieties and rootstocks.
Duration:
October 2008 to May 2013
Highlights:
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 world wide.
Immediate Objectives :
To develop new grape cultivars of improved fruit and plant characters.
To identify superior clonal selections among the existing table, raisin, juice and wine varieties.
To characterize morpho-phenologically and by molecular markers for their identity.
To develop rootstocks for tolerance to biotic and abiotic stress conditions.
To popularize the new grape varieties among the farmers.
Long term Objectives :
To develop grape industry based on broad genetic base and diversified use.
Varieties that to meet the international standards in table grape, raisin, wine and juice products.
To exchange and coordinate the grape improvement programme as a nodal centre within the country.
To develop new and improved cultivars/hybrids through breeding, non-conventional hybridization program such as somatic hybridization, embryo rescue and genetic engineering for improved berry and bunch characters, higher tolerance (immune) to dreaded diseases (mildews) soil moisture and salt stress.
All the progenies will be assessed as own root and as grafted plants on standard rootstock (DogRidge).The suitability of these will be evaluated in separate groups such as ;
a). Table grapes/ Raisin grapes /. Wine grapes/. Juice grapes/ Rootstocks
b) Closely related species/genera for use in grape improvement through hybridizations and gene transfer.
The project will be implemented at the Centre which will be funded fully by the Indian Council of Agric. Research, New Delhi through plan and non-plan schemes of NRCG, Pune. However attempts will be made to obtain adhoc projects and sponsored schemes of ICAR/DBT/ APEDA.
