利用TPS夏播生产优质实生种薯的研究──夏播实生种薯和常规实生种薯的比较

A STUDY ON THE SUPERIOR SEEDLING SEED TUBER FROM TPS SOWN IN SUMMER──COMPARISONS OF SEED TUBERS FROM TPS SOWN IN SUMMER WITH CONVENTIONAL SEEDLING SEED TUBERS

通过夏播实生种薯和常规实生种薯的比较试验，揭示了夏播实生种薯具有带毒少、出苗率高、长势强、退化轻、晚疫病轻、产量和淀粉含量明显提高等特点．进一步证明利用马铃薯实生种子夏播生产优质实生种薯是效果显著，完全可行的。

In this paper,comparisons of the sced tubers derived from TPS sown in summer with the conventional seedling sced tubers were made.For the former,the emergence rate was high and the incidence or the plants infected with PLRV and late blight was low.Furthermore,the Vigor of plants was high and high tuber yield and high starch content can be obtained.
