However, its potential remains untapped due to the limited availability of short-duration, high-yielding varieties capable of outcompeting other <em>rabi</em> crops. Considering this notion, we have evaluated twenty-one F<sub>2</sub> and six BC<sub>1</sub>F<sub>1</sub> populations derived from seven diversified parents of <em>B</em><em>rassica</em> <em>juncea</em> following a Randomized Complete Block Design at Sher-e-Bangla Agricultural University. Based on key agronomic traits, the genetic components, heterosis, inbreeding depression, and gene action were studied to select early maturing and high-yielding populations. The percentage of heterosis was manifested in various cross-combinations, including P4 ​× ​P6 (91.45% for yield per plant) and P5 ​× ​P6 (28.52% for thousand seed weight), emerging as promising candidates for increasing productivity while managing negative inbreeding effects. Conversely, significant inbreeding depression was noted in traits like days to siliquae maturity and yield, particularly in crosses, P1 ​× ​P2 (6.29%) and P3 ​× ​P5 (21.74%), underscoring the need for careful selection in breeding programs to mitigate these effects. Variance analysis indicated that both additive and non-additive genetic interactions play a pivotal role in the inheritance patterns of the traits of interest. Among the six backcrosses, one promising line was (P5 ​× ​P6) ​× ​P5, demonstrating early maturity (107.00 DAS) with improved seed yield (12.47 ​g). This combination exhibited the potential for enhancing the adaptability and productivity by maintaining the maturity index and accelerating yield. Furthermore, significant phenotypic variation across yield-contributing traits was notable, whereas thousand seed weight and yield per plant showed high broad-sense and narrow-sense of heritability. Besides, positive correlations between seed yield and its attributing traits were noted, suggesting potential avenues for selection breeding.

The results demonstrated that the nodule number and nitrogenase activity of both varieties significantly increased after ARC microbial inoculants treatment, with the highly susceptible variety AH24 showing a greater increase. For photosynthetic parameters, both varieties also increased after ARC microbial inoculants treatment, but the increase was greater in the moderately resistant variety AH1 than in the highly susceptible variety AH24. Finally, we found that the yield and yield-related traits of the moderately resistant variety AH1 were better than those of the highly susceptible variety AH24. After ARC microbial inoculants treatment, the yield traits of both peanut varieties still increased significantly, but the degree of increase of the moderately resistant variety AH1 was smaller than that of the highly susceptible variety AH24. In addition, the abundance of <em>A. flavus</em> in the rhizosphere soil of the two varieties significantly decreased after ARC microbial inoculants treatment, with no significant difference between the varieties.
