Influence of Seed Size on Seed Quality, Yield and Yield Contributing Characters in Soybean (Glycine max L. Merrill)

摘要

The medium seed size variety ]S 335 performed better than all small and bold seed variety in respect of yield and yield contributing characters. Medium seed size recorded significantly higher germination percentage (94.95%) followed by small and boldseed size. Medium seed size (JS 335) showed maximum vigour index (18.78) than the other seed sizes. The root length and shoot length was significantly superior in bold seed size as compared with small and medium seed size genotypes. The medium seed cultivar reported the highest number of pods per plant and test weight as compared to small and bold seed cultivar. The highest seedling fresh weight, highest seedling dry weight, higher root length (cm) and shoot length (cm) was recorded by bold seed size variety TAMS 38 than rest of the seed size. Most of the characters like grain yield per plant, test zoeight, germination percentage, root length, shot length and vigour index are decreased with decrease seed size. Hence, it is advisable to use bold and medium seed sizes for better seed quality.
