Bacterial wilt triggered by Ralstonia solanacearum is one of the major devastating diseases causing significant yield reduction in eggplant. F₁ hybrids (18 CARI-1 based F1 hybrids and 12 publicly available hybrids/varieties) were evaluated for bacterial wilt resistance, yield, and yield attributing traits. CARI-1 based F₁ hybrids showed superiority in yields, however showed a varied level of resistance to bacterial wilt. Further, inheritance and gene action involved in resistance to Ralstonia solanacearum was studied. CARI-1 was crossed with two susceptible parents, Arka Neelachal Shyama and Pusa Purple Long to develop six generations for both the combinations. The genetic control of resistance to bacterial wilt was found to be polygenic in the case of the Arka Neelachal Shyama x CARI-1 derived population. While di-genic with complementary gene action in the case of Pusa Purple Long x CARI-1 F₂ population, however deviation in expected ratios was observed in back cross populations. Generation mean analysis revealed the presence of epistasis. For Arka Neelachal Shyama x CARI-1 derived population, owing to the prevalence of additive × additive non-allelic interaction with a negative sign, delaying of selection to later generations, otherwise inter mating between the selected segregates accompanied by selfing for one or more generation(s) is advised for the aggregation of favorable alleles for enhancement of resistance. Similarly, for Pusa Purple Long x CARI-1 population, the simple selection can be efficient due to the prevalence of additive gene action. The inheritance details accumulated in this study would facilitate the introgression of bacterial wilt resistance into elite commercial genotypes.

青枯雷尔氏菌引起的细菌性枯萎是导致茄子产量大幅下降的主要破坏性疾病之一。评价了F ₁杂种（18个基于CARI-1的F1杂种和12个公众可获得的杂种/品种）的抗青枯病性，产量和产量归因性状。基于CARI-1的F ₁杂种表现出较高的产量，但对细菌枯萎病表现出不同程度的抗性。此外，遗传和基因作用涉及对青枯雷尔氏菌的抗性被研究了。CARI-1与两个易感的父母Arka Neelachal Shyama和Pusa Purple Long杂交，为这两种组合培育了六代。在对Arka Neelachal Shyama x CARI-1衍生种群的情况下，发现对细菌性青枯病的遗传控制是多基因的。如果是Pusa Purple Long x CARI-1 F ₂，则具有互补基因作用的双基因人口，但是在回交群体中观察到预期比率的偏差。世代均值分析表明存在上位性。对于Arka Neelachal Shyama x CARI-1衍生种群，由于存在加性×加性非等位基因相互作用并带有负号，因此选择延迟到后代，否则所选分离之间的交配伴随着一个或多个世代的自交建议将有利的等位基因聚集以增强抗性。同样，对于Pusa Purple Long x CARI-1种群，由于加性基因作用的普遍性，简单选择可能是有效的。在这项研究中积累的遗传细节将促进细菌枯萎抗性渗入优良的商业基因型。
