1
Largest continent in the world with approx 60% of the world’s population Tropical Asia (India, Indonesia, Philippines, Thailand and Vietnam ) accounts for 26% of world’s population Unfortunately this continent also accounts for the largest number of under nourished population in the world - attributed to low fruit and vegetable consumption 70% malnourished children in Asia Vegetables known to provide micro nutrients that improves health

3
Largest economic growth regions in the world - in South and SE Asia Dominated by India and China Thailand, Vietnam, Indonesia, Philippines clocked GDP per capita growth above 150% over last 10 year period USA it was 26% and UK showed single digit

Economic growth in tropical Asia – GDP per capita Country% improvement India130.6 Indonesia199.3 Philippines154.8 Thailand133.1 Vietnam214.8 UK6.3 USA26.7
5
Higher growth rate in GDP -- purchasing power is better New technologies accepted easily Hybrid seed technology was well accepted during this phase in the SE Asian countries Increase was over 10-15% annually in these countries during this period Vegetable production kept pace with increase in area and productivity
6
World’s economy is shifting from west to east Millions expected to move out of poverty Middle class will rise from 1.8 billion in 2010 to 3.2 billion in 2020 85% of this population will be in Asia

Country Area under vegetable crops (AGR%) Production of vegetable crops (AGR %) India2.02.59 China4.724.55 Thailand1.262.37 Vietnam1.792.33 Philippines1.171.08 Annual Growth Rate of Vegetable Production in Asia 2001 - 2010
8
Global vegetable production largely driven by increase in area and expansion in SE Asia and China Trend due to high net returns per unit area, higher income even with small land holdings Impact on poverty through employment generation since vegetable cultivation is labor intensive In addition, provides nutrition security Vegetable production stagnant in developing countries during the same period
9
Vegetables are the fastest growing crop sector in the world Annual increase - world over at 2.8%, Asian countries 3.86%, India 2.46% and China 5.93% Corresponding figures for other crops were negative or around 1% More land area taken up with vegetable crops in Asia In India also area under vegetables is increasing at a rate greater than for cereals, pulses, oilseeds and fiber crops Provides a major opportunity for investing in the fastest growing crop sector Vegetable revolution is the next green revolution after rice and wheat
10
Solanaceous crops - tomato, chilli, eggplant and sweet pepper Cucurbitaceous crops - watermelon, melon, bitter gourd, ridge gourd, cucumber Brassica - cabbage and cauliflower besides leafy vegetables Strong regional preferences of varieties in eggplants and chillies In solanaceous crops, OPs predominated till beginning of 90s Hybrid usage increased rapidly in tomato and chillies and to a lesser extent in eggplants In the last decade, it was 10-15% annually Area under vegetables growing – new areas added & other crops being replaced
11
Hybrids in tomato and chillies have spread rapidly in S E Asia Breeders had to develop hybrids with locally acceptable fruit and plant traits Market segmentation - a challenge to the breeder In tomato, hybrids developed for spring / summer / main season, indeterminates with resistance to important diseases In chillies, hybrids developed to suit local needs with resistance to important diseases

13
With adoption of hybrid seed technology average productivity has risen approximately by 20-25% Improved agronomic practices like drip, mulch, fertigation also helped exploit yield increases In India, yields can be as high as: tomato >120 t/ha; chilli pepper 45 t/ha This compares with best in the world (California for tomato and Mexico for chillies) With better adoption of technology productivity will increase in more areas
14
Higher yields Longer harvesting period Better adaptability Better transport qualities Nutritional value Disease resistance
15
White fly transmitted gemini virus - leaf curl Groundnut bud necrosis virus (GBNV), Capsicum Chlorosis Virus Bacterial wilt Early and late blight
16
Viruses – Chilli veinal mottle virus, CMV, GBNV, leaf curl virus Anthracnose fruit rot (Colletotrichum capsici, C. gloeosporiodes, C.acutatum) Powdery mildew Bacterial wilt
17
Tomato Ty series (Ty 1 to Ty 6) – complete resistance stable over space and time? GBNV: source of resistance and genetics Bacterial wilt – complete resistance in warm humid regions? Early and late blight: stable gene for resistance
18
Chilli Resistance to leaf curl virus, GBNV Fruit rot: stable resistance to Colletotrichum species and races General threats New viruses, strains of the virus, races in late blight Segmentation in market needs
19
New efficient production systems like drip, plastic mulch, fertigation, micro nutrients Protected cultivation - net houses and sophisticated green houses Choice of crops and suitable varieties Remote area production Impact of climate change Changing disease and pest scenario
20
Investments required in research Innovations in investigations Fundamental and basic research necessary in tackling new disease / insect resistance Public institutes to develop strength in basic research Possibilities of forging relationships between public institutes and private sector
21
Locating new sources of resistance Locating different resistant gene(s) Developing efficient screening techniques Basic studies on pathogens Pre-breeding in PPP mode Marker development
22
Basic and fundamental research to be encouraged in research institutes and universities Research funded by private sector can be encouraged It could be on exclusive or non-exclusive basis Research funded by private companies will bring public institutes closer to the market APSA – AVRDC model with a consortium of seed companies can be replicated
23
Private sector can float fellowships/scholarships in Universities for post graduate studies Seed companies with requisite facilities can be recognised as research centres Refresher courses can be organised for plant breeders as in UC, Davis
24
Providing germplasm Providing resistant sources Successful collaborative projects (APSA sponsored) ◦ Ty2 marker development ◦ Development of SSR markers in tomato ◦ More recently on Ty gene(s) deployment over space Exclusive research projects
25
Significant role in bringing seed companies under one umbrella Organizing trade between companies Organizing training programs like on seed testing, pathology, marker assisted selection Harmonization of phyto-sanitary rules Promotion of technical and economic cooperation
26
NBPGR should open up to private seed companies for providing germplasm as in vogue in CGIAR Institutes Passport data to be available on all accessions and on the website Procedural formalities to be simplified for procurement of germplasm including signing of MTA /SMTA Bottle necks not to be created under bio-diversity treaties when the material is already in use by breeders all over the world Adoption of models which will help in rapid progress of germplasm augmentation and exchange
27
Identification of research needs in tomato and chilli especially on resistance to diseases Building relationships and creating PPP among Institutions to work on identified projects Formulation of effective action plans and strategies Identifying deliverables in the form of improved varieties Overall aim will be to improve quality of life of tomato and chilli growers in Asia
