Generation mean analysis in chilli (Capsicum annum L.)
Abstract
The generations mean analysis involving six generations (P1, P2, F1, F2, B1 and B2) was carried out to study the nature and magnitude of gene effects for 13 characters in chilli. The study was conducted at Departmental Farm of Agricultural Botany, College of Agriculture, Dr. B.S.K.K.V., Dapoli during year 2011-12. The Mather’s individual scaling tests and Cavalli’s joint scaling tests were used to detect the presence or absence of the epistatic interactions. The results obtained showed the importance of additive, dominant and all three types of epistatic interactions for three crosses and thirteen characters viz., Days to first flowering, days to first picking, plant height (cm), number of branches per plant, fruit length (cm), fruit diameter (mm), number of seed per fruit, number of fruits per plant (green), green fruit yield per plant (g), number of fruits per plant (red), red fruit yield per plant (g), days to last picking and capsaicin content. For majority of crosses duplicate epistasis was observed. While the complimentary epistasis was observed for the cross Jwala x DPL-C-5 for days to first flowering, number of red fruit per plant and days to last picking, fruit diameter and fruit length for the cross Jwala x Parbhani Tejas and number of seed per fruit in the cross Jwala x AKC-08-95-05.
