Relationship between genetic distance and heterosis for yield and morphological traits in winter canola (Brassica napus L.)

Abstract: Genetic distance among canola cultivars was estimated through multivariate analysis. Thirty cultivars from various sources were analyzed and clustered based upon five morphological characteristics and yield components-crown diameter, number of branches plant(-1), number of pods plant(-1), number of seeds pod(-1) and yield plant(-1) -and placed in three distinct clusters. Two cultivars from each cluster were selected as parents and 15 partial-diallel inter- and intra-cluster crosses were made between the six se… Show more

“…In addition, Arunachalam (1977) has also proven the role of additive x additive epistatic interactions in causing heterosis. Findings on good correlations between the genetic distance of parents (from performance and molecular marker data) and the performance of their hybrids were similar to those reported in cacao and several species (Ghaderi et al, 1984;Shamsuddin, 1985;Cox and Murphy, 1990;Cruz et al, 1994;Ali et al, 1995;Diers et al, 1996;Xiao et al, 1996;Dias and Kageyama, 1997a;Kisha et al, 1997;Lanza et al, 1997;ManjarrezSandoval et al, 1997;Saghai Maroof et al, 1997;Burkhamer et al, 1998). However, there are several reports describing poor correlations (Vaillancourt et al, 1995;Cerna et al, 1997;Helms et al, 1997;Chowdari et al, 1998;Fabrizius et al, 1998;Perenzin et al, 1998;Tenkouano et al, 1998;Bohn et al, 1999;Joyce et al, 1999;Kidwell et al, 1999;Sant et al, 1999).…”

“…É enfatizada em trabalhos com diferentes culturas (Julfiquar et al, 1985;Jaylal & Haider, 1994;Ali et al, 1995;Dwivedi & Mitra, 1996). Segundo Wilches (1983), o agrupamento e a avaliação de material genético por meio da diversidade genética, com base em evidências científicas, são importantes para o conhecimento da evolução da espécie e para a localização e o intercâmbio de recursos genéticos.…”
