“…Under greenhouse conditions, 17 pepper genotypes showed 44 days to 50% flowering and 48 days to first fruit set [23]. Other authors reported heterotic crosses of high frequency over better parent and standard check for days to first flowering, days to first harvest, growth and yield traits [24,25]. These findings are in disagreement with ours because our results have not shown significant difference between parent genotypes and androgenic lines.…”

The biology of pepper growth and development is strongly dependent on complex influence of environmental abiotic factors as light, temperature, air humidity and soil moisture. The presence and length of different pepper phenophases are variety characteristics, which they expressed as result of the development in specific agroecological conditions. In this study the vegetation period as earliness indicator of seven androgenic pepper lines derived from 3 different sweet pepper varieties was studied during four years experiment under greenhouse conditions. The studied androgenic pepper lines KK1 and KK2 were derived via androgenesis from the sweet pepper variety Kurtovska kapia (KKk), P3 and P4 from the variety Piran (Pk) and F5, F6 and F7 derived from the variety Feherozon (Fk). The length of the vegetation period of the seven androgenic lines was compared to the vegetation period of their parental genotypes, respectively. Based on estimated length of vegetation period the androgenic lines were grouped in two groups as early ripening pepper androgenic lines and late ripening pepper androgenic lines. Alongside, there is a significant and positive association of days to flowering and days to fruiting with days to horticultural and physiological fruit maturity.

“…Heterosis is the basis for improvement of crop yield which is due to superior gene content of inbred parents and, contributes to superior performance ( Mather 1955 ). Significant heterosis and heterobeltiosis for yield and horticultural characteristics of hybrid chilies have also been reported more generally ( Abrham et al 2017 , Ganefianti and Fahrurrozi 2018 , Kumar et al 2014 , Nagaraju et al 2017 , Patel et al 2010 , 2014 , Prasath and Ponnuswami 2008 , Rekha et al 2016 , Shrestha et al 2011 ). The testing of maintainers is needed to confirm that the backcrossed female CMS lines with the maintainers would accurately express the heterosis in the F 1 hybrids.…”

Selfing and crossing methods were used to develop the cytoplasmic male sterility (CMS) lines from 2 elite F 1 hybrids of CMS hot chilies. The pungency of the CMS lines was improved by backcrossing with the B cultivar. The first and second backcrossed progenies of the CMS lines showed significantly higher capsaicin contents than the F 1 hybrids. One good female line K16 × BBC2 (K16), was selected and backcrossed with 3 good maintainer cultivars, C5, C9 and C0. Some incomplete male sterility of pollens was demonstrated in the F 1 hybrids and the 1 st backcrossed progenies while the partial sterility disappeared by the stage of the second and third generations of backcrossing. When K16 and P32 were crossed with restorers, fruit yields and yield components of certain F 1 hybrids, parental lines and commercial varieties were significantly different. Heterosis of yield and yield components of the F 1 hybrid chilies was significant. When K16 was used as a female parent, positive and significant heterosis of the F 1 hybrids was the same as P32. Moreover, significant GCA of the restorer lines, C7, C8 and C9, was observed in some horticultural characteristics. Furthermore, significant differences of the specific combining ability of some characteristics were observed in a few F 1 hybrids.
