The results of evaluating the productive and exterior characteristics of the rabbits of the mother's maternal lines and the parent forms of the HYLA cross are highlighted in this article. The significance of such breeding features was determined: live weight, straight length of the body, chest circumference, and shoulder width, index of loss, volume of ejaculate, multiplicity and conservation of rabbits before weaning. HYLA MAX parent males have a greater live weight than 1,25 kg (p < 0.001) than males of the maternal HYLA GPC parent line. The coefficients of the variability of this feature in both groups of males were low – 8,38 and 9,68 %, respectively. Analyzing the live weight and body measurements of HYLA GPD and HYLA NG females, no significant difference was found. However, for multiple fertility, females of the maternal form HYLA NG predominated by a 1,59- headed colemate of the maternal HYLA GPD line (p < 0,001). Reliable correlation bonds in male HYLA GPC between live weight and width of the waist are r = + 0,654 (p < 0,001); in males HYLA MAX between live weight and the chest circumference of the shoulders - r = + 0,708 (p < 0,001); in females HYLA GPD between the width of the waist and multiple fertility - r = + 0,445 (p < 0,05); in HYLA NG females between live weight and survival are rabbits to weaning – r = - 0,158.
