An assessment of somaclonal variation induced with regard to certain morphological, cytological and biochemical parameters was made in the regenerants. Field performance of the R1 and R2 generation plants with respect to some yield traits was also evaluated. Higher morphogenetic potential was observed in the CC genome bearing species where as AA, BB genomes alone and in combination showed lower morphogenetic capacity. In 20.5 per cent of the total regenerants studied, cytological abnormalities were observed. Variation in the isozyme banding pattern of peroxidase, malate dehydrogenase and catalase was observed in 13.5 per cent of the total regenerants analyzed. A number of R1 plants showed significantly improved agronomic characters and higher oil content. Consistently high per cent oil content was recovered in four R2 lines of B. napus and two of B. carinata. However, segregation was observed in R2 generation of some selected R1 plants for traits like plant heig Hersteller: LAP Lambert Academic Publishing Marke: LAP Lambert Academic Publishing EAN: 9783846509197 Kat: Hardcover/Naturwissenschaften, Medizin, Informatik, Technik/Biologie/Genetik, Gentechnik Lieferzeit: Sofort lieferbar Versandkosten: Ab 20¤ Versandkostenfrei in Deutschland Icon: https://www.inforius-bilder.de/bild/?I=WLKiAG7QGKV%2FM7HLhhkoLgezV3Cog1sunJMZJb3j5mo%3D Bild:
