Program! 
• Funded by legislature 1969! 
• 7 hybrids, 16 vegetable varieties 
and Papaya! 
• Seed production on all islands; 
papaya on Kauai! 
• Need a Vegetable Breeder at UH! 
• Need a Seed Specialist! 
•
Seed Programs 
• Public, Government 
• Private (narrow germplasm) 
• Artisanal or Informal 
(diverse germplasm) 
Home-gardening 
Indigenous 
Community
Decline of Public Breeding 
Programs 
• decline over past 40-50 years 
• Nationally and in Hawaii 
• Land-grant universities shifted 
to produce ‘products’ that were 
more profitable, royalties, patents 
• less classical breeders, more 
molecular biologists
Alternative Breeding 
Programs 
• Public breeding initiatives, 
participatory models 
eg Organic Seed Alliance & Cornell 
• Plant breeding clubs 
• Seed Saving Networks
Hawaii Statewide Seed Assessment 
SurveyMonkey.com 
N= 128 responses
Farm Size in Survey 
• Range= 0-250 Acres 
• Most farms= 1 Acre 
• Average size= 10 Acres 
• Larger farms= 250, 
195, 75, 10-20
Environmental Conditions in Farm 
Frequency mentioned 
• Rainfall- 9,15, 30.. 100s, 125, up to 180” 
• Elevation- sea level, range 200 to 
1000s, 
and 1000-3000 ft

• Average= 10 years 
• median= 5 years 
• Less than 3 years= 
43%
Have You conducted crop improvement, breeding?

Goal of Variety Trials 
• Expression of the plant due to genetics 
or to the environment! 
• ID varieties adapted to the land 
(replace inputs with well adapted varieties)
Experimental Design 
• Observational (non-replicated) trials: 
screen varieties, ! 
evaluate sources, check trueness to type! 
vs! 
• Replicated trials ! 
(results are not due to environment alone)!
Population Numbers 
to assess genetic variability" 
• Corn 30! 
• Brassicas 30! 
• Carrots 50! 
• Radishes 50! 
• Tomatoes/pepper 10! 
• Squash, cucumbers 10! 
• Beans 30! 
(source: OSA Farm Variety manual)!
Consistent Treatments" 
• Growing seedlings! 
• Transplanting/planting! 
• Irrigation! 
• Cultivation! 
• Fertilization! 
• Pest management! 
• Harvesting!
Trial Evaluation" 
• Log sheet 
• scoring (index) vs measuring! 
Scoring may be more valuable 
and quicker-! 
• All on same date, scoring system! 
Scale of 1-9 ! 
(1= least, 9= most desirable),!
Collaborative Research Trials" 
Hawaii Trial Network, on different islands 
to compare several microclimates and 
production niches; trial database with 
trial network to follow performance 
on different microclimates.! 
(Micaela Colley, HI Public Seed Conf. 2010)! 
• Lettuce! 
• Tomato!
Tomato response to Nitrogen 
Heirloom vs New Hybrid varieties, response
Leafies 
response to 
Phosphorus

  • 9. Seed Programs • Public, Government • Private (narrow germplasm) • Artisanal or Informal (diverse germplasm) Home-gardening Indigenous Community
  • 10. Decline of Public Breeding Programs • decline over past 40-50 years • Nationally and in Hawaii • Land-grant universities shifted to produce ‘products’ that were more profitable, royalties, patents • less classical breeders, more molecular biologists
  • 11. Alternative Breeding Programs • Public breeding initiatives, participatory models eg Organic Seed Alliance & Cornell • Plant breeding clubs • Seed Saving Networks
  • 12. Hawaii Statewide Seed Assessment SurveyMonkey.com N= 128 responses
