作者们以马铃薯新型栽培种(S.tubero-sum×Andigena)的株系 W553-4为母本同栽培品种(S.tuberosum)的农林1号进行了杂交,并获得大量杂交后代。然后,着眼于产量,从中选出若干高产杂交株系,其中最高产的有两个株系。在3种密度条件下,对它们的高产原因进行了探讨。本报告在揭示高产原因的同时,记录了显著的高额产量。
The authors crossed with Nonglin 1 of S. tuberosum using the strain W553-4 of S. tubero-sum × Andigena as the female parent and obtained a large number of hybrid progeny. Then, focusing on yield, a few high-yielding hybrids were selected, two of which were the most productive. Under the three kinds of density conditions, the reasons for their high yields were discussed. This report, while revealing the causes of high production, recorded significant high yields.
