本文研究了国内最新配制的马铃薯实生种子9个杂交组合,通过试验,分析和比较了F_1实生苗世代主要经济性状的表现,综合评价了各个杂交组合在杂种优势利用中的价值,筛选了可用于商品生产的优良组合.对主要亲本的配合力进行了估计,为实生种子利用提供科学依据并研究优良自交系.试验结果表明:W_4×NS_(79-12-1),W_5×NS_(79-12-1)和肯德×8342-36为优良杂交组合,W_4×NS_(79-12-1)可用于实生种薯生产.自交系NS_(79-12-1)和8342-35为优良自交系,后者在提高单薯重量降低单株结薯个数上有较高的配合力.本文还讨论了我国马铃薯实生种子选育和杂种优势利用的进展和发展潜力.
In this paper, nine hybrid combinations of potato seedlings newly formulated in China were studied. The main economic traits of F_1 seedlings were analyzed and compared. The value of hybrid combinations in utilization of heterosis was evaluated. Good combination of the production of the goods.The combining ability of the main parents was estimated to provide a scientific basis for the utilization of the seed and to study the fine inbred lines.The results showed that: W_4 × NS_ (79-12-1), W_5 × NS_ (79) -12-1) and Kink × 8342-36 were excellent hybrid combinations, W_4 × NS_ (79-12-1) could be used for seedling production in inbred lines. Inbred lines NS_ (79-12-1) and 8342-35 were Excellent inbred lines, the latter had higher combining ability in increasing the number of tubers per plant and reducing the number of tubers per plant.This paper also discussed the progress and development potential of potato seed selection and heterosis utilization in China.
