Variation in the Quantitative Characters of Androgenic Pepper Lines Derived from Hybrid Capsicum frutescens L. x C. chinense Jacq In the presented work doubled haploid lines (DH lines) obtained in anther cultures of pepper hybrid (Capsicum spp.) were investigated, regarding their biometrical characteristics. The experiment was carried out over 2007-2008. The research material consisted of R2 and R3 generations of three androgenic lines: FCHX, FCHXI and FCHXII, derived from interspecific pepper hybrid C. frutescens L x C. chinense Jacq. The biometrical analyses of R2 generation revealed that in case of FCHXI line five of the six analysed fruit parameters showed phenotypic homogeneity. Four characters of FCHX line were homogenous, while in case of FCHXII line only the number of seeds per fruit was uniform. In the successive year when R3 generations, obtained as a result of R2 plants self-pollination, were evaluated, statistical analysis confirmed phenotypic uniformity of each of the tested fruit characters. Simultaneously, Scheffe significance test demonstrated a high variation between the three analysed anther-derived lines of C. frutescens L.x C. chinense Jacq. |
