高中《生物》课本 P150上,谈到三倍体西瓜的培育过程。其中有这样一段话:“……用四倍体植株作母本,用二倍体植株作父本,进行交配,就能在四倍体植株上结出三倍体西瓜的种子。”对此,不少师生提出另一种设想:如果反过来,用二倍体(2n)植株作母本,用四倍体 High School “Biology” textbook P150, talked about the development of triploid watermelon. There is a passage like this: “... With tetraploid plants as mother plants, diploid plants used as male parents for mating can produce seeds of tetraploid watermelons on tetraploid plants.” To this , Many teachers and students put forward another idea: If in turn, with diploid (2n) plants as the female parent, tetraploid
