벼 담수표면산파재배시 주요 품종들의 적응성을 평가하기위하여 1996~1998년에 국립식량과학원 벼맥류부 벼 시험포장에서 공시품종들의 중요한 형질인 입모율, 도복 및 수량성 등을 검토한 결과를 요약하면 다음과 같다.
1. 입모율이 80% 이상인 품종은 동안벼, 호안벼, 동진벼,80% 이하인 품종은 화영벼, 팔공벼, 대산벼 등 이었다.
2. 도복이 발생하지 않았거나 경미한 품종은 대산벼, 동안벼,금남벼, 안산벼, 주안벼, 안중벼, 화남벼, 금남벼, 오봉벼, 도복발생이 심했던 품종은 금오벼, 화영벼, 동진벼, 낙동벼 이었다.
3. 당 수수와 수당립수는 조생종이 중생종과 중만생종에 비하여 현저히 적었고, 등숙비율은 중생종과 중만생종간에는 차이가 없었으나 조생종은 다소 낮았다.
4. 쌀 수량은 중만생종과 중생종간에는 별 차이가 없었으나,조생종은 4품종 모두 중생종과 중만생종 품종보다 0.79~0.85MT/ha정도 낮았다.
5. 따라서 벼 담수표면산파재배시 주요 품종들의 입모, 도복 및 수량성 등을 평가해 본 결과 적응성이 양호한 품종은 동안 벼, 대산벼, 호안벼 이었다.
This study was conducted to estimate the adaptability of some rice varieties for wet flooded direct seeding. Characters such as seedling stand, lodging index and milled rice yield are very important factors in order to get stable yield in direct seeding. These characters were compared among the 17 varieties which belong to early, medium, and mid-late maturity groups. Donganbyeo, Hoanbyeo, and Dongjinbyeo showed over 80 percent of seedling stand. Lodging did not occur in Daesanbyeo, Donganbyeo, Geumnambyeo, Ansanbyeo, Juanbyeo, Anjungbyeo, Hwanambyeo, and Obongbyeo. On the other hand, Geumobyeo, Hwayeongbyeo, Dongjinbyeo, and Nagdongbyeo showed severe lodging. The numbers of panicles and spikelets per in early maturing varieties were lower than those in medium and mid-late maturing varieties. There was no difference among medium and mid-late maturing varieties in the ratio of ripened grain. Milled rice yield was not different in medium or mid-late maturing varieties, whille in early maturing varieties it was different from 0.79 to 0.85MT/ha which was lower than in medium or mid-late maturing varieties. Consequently, Donganbyeo, Daesanbyeo and Hoanbyeo was desirable for wet flooded direct seeding in consideration of seedling stand, lodging and yield.
