Features of heterosis manifestation in interlinear hybrids of sweet pepper in unheated film greenhouses

The dynamics of changes in an important economic trait sweet pepper “average fruit weight” and the manifestation heterosis have been studied on example 10 hybrids their parental lines with multiple harvests unheated film greenhouse. It was found that average weight, regardless its value, maximum relatively stable during first 5 harvests, which corresponds to return early yield month fruiting. At last collection, there a decrease weight by 1.3-2.5 times. has established late occurs at later date is less pronounced than lines, indicates higher adaptive ability. With harvest 3 combinations, level true 5.4-19.7%, hypothetical 5.4-24.4% 7 hybrids. 50% hybrids, value varied, but had same character; change sign opposite noted.2 hybrid combinations more were identified - (Bs1xF46Kt22706) (San1xF46Kt2181) varying traits within 77-99 g 81-123 g. effect 80% large-fruited (17.6-27.3%) medium-fruited (8.5-49.3%) noted after July 21.The does not correspond experiment associated reaction compared extreme temperatures period formation.
