Genetic value of the source forms as components of breeding is characterized by their combining ability, the ability to give heterotic hybrids. Studies of combining ability of the source forms of sweet pepper were conducted in glass hydroponic greenhouses (RTCG SE RPA) "Pushcha-Vodytsya" in 2011 – 2012. The object of research was taken a collection of source forms (lines) of sweet pepper RTCG SE RPA "Pushcha-Vodytsya" and hybrid combinations created from them. The test was conducted in three replications. The scheme of planting was 90?40 cm, the number of plants per 1 m2 – 2.9 pcs. Evaluation of combining ability of the source forms of sweet pepper was carried out by breeding characteristics, "early yield", "total yield". As a result of the studies, by topcrosses method, the peculiarities of the manifestation of the effects of general (GCA) and constants of specific (SCA) combining ability in terms of "early yield" and "total yield" of the source forms of sweet pepper in a greenhouse were set. For selection to early yield we recommend using the source forms: PV-107, PV -110, PV -111, PV -118, PV -119, PV -120 with high SCA. For selection to the total yield we recommend using the source forms: PV -105, PV -107, PV -109, PV -111, PV -118, PV -122 with high GCA and SCA.
