| 摘 要： | 经过20多年的马铃薯脱毒技术的研究与应用，目前中国不同地区繁育的同一品种马铃薯脱毒种薯，其继代植株表现出比较大的差异。笔者以辽宁本溪马铃薯研究所（BX）繁育的‘早大白’种薯为对照，研究了河北坝上农科所（HB）和黑龙江大兴安岭农科所（HLJ）2地繁育的马铃薯‘早大白’种薯的继代表观遗传变异的生物学性状和产量品质的变化。结果表明：河北坝上繁育的脱毒种薯继代植株在苗期长势较旺，进入现蕾期以后，黑龙江大兴安岭繁育脱毒种薯继代的株高、茎粗、叶面积迅速增加，开花期延后，生育期延长，有利于干物质的合成与积累。出苗后50天收获，河北坝上繁育脱毒种薯继代块茎产量和商品率与对照无明显差异，而黑龙江大兴安岭繁育脱毒种薯继代块茎产量和商品率均低于对照。出苗后60天收获，黑龙江大兴安岭繁育脱毒种薯的继代产量比对照提高30.26%，商品率无明显差异，同时块茎中可溶性蛋白、可溶性糖、淀粉和Vc含量与对照无明显差异。

| Abstract: | After about 20 years of potato virus-free technology research and application,the same species of virus-free potato bred in different areas,the following generation plant showed a greater change at present.In this paper,'Zao Dabai'potato cultivar that was bred from Benxi Potato Research Institute of Liaoning province(BX),Bashang Agricultural Science Academy of He Bei province(HB)and Da Xinganling Agricultural Science Academy of Heilongjiang(HLJ)province,they were used as materials for studying the epigeneti... |
