【摘要】 本文通过对4个具TM^-2nv连锁基因番茄新晶系的配合力及利用价值的分析结果表明,这些新品系与其它栽培品种配组的F₁组合在产量性状上具有很强的优势。TM20-0-1和TM20-0-2二品系具有较高的一般配合力效应和特殊配合力方差,是番茄杂种优势利用较为理想的丰产抗病亲本。更多还原

【Abstract】 The peper analyses the combining ability and the utilized value of four mew tomato strains with TM-2nv linked genes. The result shows that F1 hybrids of the crosses between these strains and other cultivated cultivars have strong hybrid vigor in yield character. Both TM20-0-1 and TM20-0-2 shows greater effect on general combining ability and greater variance of special combining ability. It may be considered that the two strains are ideal high-yield, disease-resistance parents in utilizing tomato hybrid vigor. (CH)更多还原
