This study was done inside an assignment that intended to break down options and strategies for the progression of a rabbit line by using two pure breeds (V-line (V), and Gabali (G)). Records of 448 packs delivered by 45 does and 16 bucks were utilized to estimate covariance, Heritability (h²), genetic and phenotypic correlations, and breeding values of litter traits were evaluated in composite of crossbreeding arrangement of ten mating groups. The initial five groups comprise of (G♂ X V♀) and reciprocal crosses (V♂ X G♀) for the other five groups. Each buck was represented as a sire to all litters in each group to create F₁ (½G ½V& ½ V½G sire breed is demonstrated first) for four parities. Weaning was performed at 28 days of kits age. Pre-weaning litter traits were measured (for instance, litter size at both birth (LSB), and at weaning (LSW); litter weight either at birth (LWB), and body weight at weaning (BWW)).  Data were examined utilizing GLM and VARCOMP procedures of SAS took after by single and multi-trait animal model investigations (AM), which performed utilizing derivate free limited maximum likelihood (MTDFREML). The results revealed that h² estimates for LSB and LSW were 0.133±0.01 and 0.15±0.063, respectively. The evaluations of coefficient of inconstancy (CV%) are 34.78% for LSB versus 39% for LSW, and 28.27% for LWB versus 33.53 % for BWW. The impact of mating groups on LSB and LSW, LWB and BWW had exceptionally significant being 7.921, 5.320, 0.402, and 0.450 kg for LSB, LSW, LWB and BWW for (G♂ X V♀), individually, while the proportional (V♂ X G♀) were 6.224, 4.80, 0.360, and 0.490 kg, separately. Parity significantly affected LSB, LWB, and BWW. Meanwhile, the impact of doe within buck as a random impact demonstrated an unacquainted impact altogether influenced all analyzed traits. Negative genetic correlation between litter size at birth and each of litter weight at birth and body weight at weaning. Additionally, environmental correlation between litter size at weaning and litter weight at birth was positive, while the environmental correlation between litter size at waning and body weight at weaning was negative but not significant. Furthermore, the precision of the evaluations of bucks breeding value (0.37 to 0.92) was higher than the exactness of doe (0.27 to 0.88) and progeny (0.36 to 0.85), which might be because of the higher number of descendants per buck. Subsequently, the outcomes demonstrated the significance of utilizing bucks of Gabali in rearing project to build the genetic advance.
