Genetic variability in CMS backcross generations and their maintainers in eggplant (Solanum melongena L.)
Journal Title: Journal of Applied and Natural Science - Year 2017, Vol 9, Issue 3
Abstract
Twelve genotypes of eggplant in BC3, BC4 and BC5 generations of CMS-lines derived from Solanum ae-thiopicum × Solanum melongena cross along with their maintainers were evaluated for eighteen quantitative charac-ters at Punjab Agricultural University Ludhiana. Analysis of variance depicted significant variation (P ≤ 0.05) for all the characters in all generations. High PCV and GCV values were observed for fruit length, fruit girth, fruit weight, number of fruits plant-1 and yield plant-1 in all generations indicating high variability in the germplasm. High heritability coupled with high genetic advance was found for peduncle length, fruit length, fruit girth, fruit weight, number of fruits plant-1 and yield plant-1 in all generations indicating the predominance of additive gene action for these traits. Thus, selections can be made from present germplasm for the development of improved CMS inbred lines with varying fruit traits.
