甘藷雜交選拔後裔主要量性狀變異對澱粉含量關係

毛賢宗

摘  要

本研究所利用品系中,有效莖葉產量變異不影響塊根含澱粉率。塊根產量變異對塊根澱粉率有負的影響,而塊根乾物率變異與塊根澱粉率有密切正相關,塊根乾物率可代表塊根澱粉率作為選拔雜交後代之指標。


The Relationship between the Variations of Main Quantitive Characteristics and Percentage of Starch Content in Hybrid Lines of Sweet Potato

S. T. Mao

Summary

     In the lines used for his study the variation of yield of effective stems and leaves didn’t influence the percentage of starch content of tuber roots.  The variation of yield of tuber roots had a negative correlation with the percentage of starch content.  There was a high positive correlation between the variations of percentage of dry matter and percentage of starch content of tuber roots.  It shows the percentage of dry matter is a selection index for the percentage of starch content.
