- Title
WILD Helianthus SPECIES USED FOR BROADENING THE GENETIC BASE OF CULTIVATED SUNFLOWER IN INDIA.

- Abstract
The present investigation has been undertaken to introgress desirable traits from wild sunflowers to cultivated sunflower. Using conventional methods of crossing, backcrossing and selection, several pre-bred lines with altered plant architecture, high yield and oil content, maturity duration and inbuilt tolerance to major biotic stresses have been developed from crosses involving diploid annuals. These recombinant interspecific inbred lines are being utilized in the national sunflower network program for development of inbred lines and heterosis breeding. The pre-bred lines were characterized through cytological and molecular techniques using sunflower specific SSRs. Diploid perennial and hexaploid species have been utilized in the program aimed at introgression of resistance to A. helianthi through various ploidy manipulation procedures. The utility of the prebreeding material in the sunflower network program in India is presented.
