Zusammenfassung:The invention relates to a subpopulation of red Rhode- Island breed, a homozygote for the golden gene, intended to producing the simple hybrid male (5A x 3B) required for obtaining, by its crossing with the simple hybrid female (5Cx5D) - the homozygote for silver gene- belonging to white Rhode-Island breed, the ROSO SL-2000 hybrid hens used in the production of consumption eggs with pigmented shell, meant for the population. The heterosomal silver and golden genes play the role in transmitting the feathering colour to the one-day-old hybrid chickens and allow to distinguish the hybrid young cocks from the hybrid young hens. The productive features of the line are: 308 eggs per foddered female in a productive cycle, with the egg average weight of 58.1 g and 60.9 g at the ages of 26 and 34 weeks, 1980 g the average female weight and 2710 g the average male weight at the age of 34 weeks; the hens lay the first egg at the age of 150 days; 95...96% youngster viability and 94...95% adult viability, 90.5% average fertility and 80.9% egg hatchability. The poultry belonging to this line are calm and resistant to diseases. Invenţia se referă la o subpopulaţie din rasa Rhode-Island roşu, homozigotă pentru gena golden, destinată producerii masculului hibrid simplu (5A x 3B) necesar realizării, prin încrucişarea lui cu femela hibrid simplu (5C x 5D) - homozigota pentru gena silver - aparţinând rasei Rhode - Island alb, a găinilor hibride ROSO SL-2000, utilizate în producţia de ouă pentru consum, cu coaja pigmentată, destinate populaţiei. Genele heterosomale silver şi golden au rol în transmiterea culorii penajului la puii hibrizi de o zi, şi fac posibilă separarea cocoşeilor hibrizi, de puicuţele hibride. Însuşirile productive ale liniei sunt: 308 ouă pe femelă furajată pe ciclu productiv, cu o greutate medie a acestora de 58,1 g şi 60,9 g, la vârstele de 26 şi 34 săptămâni, 1980 g greutatea medie a femelelor şi 2710 g greutatea medie a masculilor la vârsta de 34 săptămâni; găinile produc primul ou la vârsta de 150 zile; viabilitatea tineretului este de 95...96%, iar a adultelor de 94...95%, fertilitatea medie fiind de 90,5%, iar eclozionabilitatea ouălor, de 80,9%. Păsările din această linie sunt calme şi rezistente la boli.
