Observation Kkari1ho seed weight was 32.7 g per 100 seeds and smaller than Cheongja3ho.
Observation Kkari1ho plant height resembled Cheongja3ho.
Observation Kkari1ho first pod height resembled Cheongja3ho.
Observation Kkari1ho was highly lodging resistant under standard field conditions.
Observation Kkari1ho resisted pod shattering more than Cheongja3ho in field and indoor tests.
Observation Kkari1ho and Cheongja3ho had comparable bacterial pustule resistance in field and inoculation tests.
Observation Kkari1ho had lower soybean mosaic virus resistance in inoculation tests.
Observation Kkari1ho had comparable soybean mosaic virus resistance in field tests.
Observation Kkari1ho regional trial mean yield was 252 kg per 10a.
Observation Kkari1ho regional mean yield was 4% higher than Cheongja3ho.
Recommendation The authors expect Kkari1ho to replace landraces because of lodging and bacterial pustule resistance.

Intervention effect H. zea densities exceeded the podding threshold at some sites without yield differences among treatments.
Association Yield was negatively related to injured flower number.
Association Yield was negatively related to cumulative flower number.
Association H. zea density was related to increased injured flower counts.
Association No direct link between H. zea density and yield loss was observed.
