| dc.description.abstract | Commercialization of cytoplasm-nuclear genetic male sterile (CNMS) hybrids in chilli would be justified if CMS hybrids offer additional benefits either in terms of improved performance, quality or they are comparable to conventional hybrids for defense traits. Under this premise, 42 iso-nuclear alloplasmic hybrids (21 each of A×R & B×R crosses involving 3 CNMS (A) lines, their counterpart fertile (B) lines and 7 restorer (R) lines), were evaluated at the Experimental Plots, ‘K’ Block and Hot Pepper Improvement Unit, Department of Genetics & Plant Breeding, University of Agricultural Sciences, GKVK, Bangalore during 2011 dry and rainy seasons, to assess the cytoplasmic effects in terms of parental gca effects, hybrid mean performance, sca effects and midparent heterosis on fruit yield and its contributing traits, fruit quality traits (ascorbic acid, capsaicin, oleoresin & phenols) and response to anthracnose disease and thrips infestation. A×R hybrids as a group differed significantly from those of B×R hybrids as a group for fresh green fruit yield plant-1, ascorbic acid and capsaicin contents, suggesting cytoplasmic influence on expression of these traits. Significant differences between A- and B- lines for their gca effects was an indication of male sterility inducing cytoplasm effects on the ability of the lines to combine with common testers. The differences between A×R and B×R crosses for mean performances, sca effects and mid-parent heterosis was significant. However, the direction and magnitudes of differences (where detected) was of lower magnitudes and varied with the trait as well as nuclear genetic background of the genotype and the crosses. | en_US |
