Abstract
大豆種子在25℃浸水4天後，再進行發芽試驗之發芽率可作為測定大豆種子耐水性之指標。種子耐水性在品種問有顯著差異，全互交分析結果控制耐水性大致有l-2對基因，基因效應為累加性及顯性，耐水性偏向隱性基因，狹義遺傳率為47％。在浸水逆境下種子吸水量與耐水性不呈顯著相關，但在正常條件下吸水量與耐水性則為顯著負相關。中南部地區秋作收穫之子實較適合於作為種子也較具耐水性。種子耐水性與貯藏力之間呈顯著正相關，但與出土能力之間的相關關係則不顯著。
The flooding tolerance of soybean seeds can be measured by the germination test after 4- day soaking at 25℃. High variation in seed flooding tolerance existed in soybean germplasm as reflected by the range of germination rate from 0 to 100%. Seed flooding tolerance was controlled by one/two effective factors, and both additive and dominance variances and high narrow sense heritability were suggested. Seed water uptake was related negatively and significantly to flooding tolerance under normal imbibition. However, the relationship was not significant under flooding stress.
Elongation ability of seedlings differed greatly among varieties. The relationship between flooding tolerance and elongation ability of seedling was not significant.
Storability of seeds was also different significantly among varieties and was a genetic character with heritability of 86%. The storability was related positively and significantly to flooding tolerance.
