【摘要】 通过对2001年和2002年两a对海南冬季辣椒品比试验结果的分析,发现在辣椒的果纵径和果横径遗传中存在超亲临界点,亲本果横径或果纵径的差值小于相应的超临界点时,其后代的果横径或果纵径出现超亲优势。果色、果面特征的遗传规律与前人研究结果一致;果头遗传以大头为显性。更多还原

【Abstract】 F1 hybrids of the pointed pepper×the pointed,the pointed× the sweet pepper were observed in 2001 and 2002. Analysises indicated there exsits a critical point for heterobeltiosis in fruit length and fruit width. When the difference of P1- P2 in the former or the latter character is less than the critical point, heterobeltiosis will be observed in their hybrid progeny in the character. Fruit color and fruit surface follow the same genetic law as the reported before. In fruit head inheritance,the big head is the dominant one.更多还原
