Multilocation evaluation of the identified accessions and identification of B/R reaction in sunflower

Abstract

Multilocation evaluation of the identified accessions: Thirty one already identified promising accessions for high yield and oil content were evaluated at three locations with two replications along with 2 checks (DRSF113 and Morden) at IIOR, Hyderabad, Solapur and Savalvihir. Eight germplasm accessions recorded higher yield than the national check (DRSF113). GMU-799 followed by GMU-189 and GP2 1217 recorded highest seed yield in evaluation trial (Fig1). These germplasm accessions will be provided to the AICRP centers for development of new populations and inbred development.10 best inbred for high seed yield and oil content were utilized in crossing with Helianthus petiolaris background two CMS lines i.e. CMS234 A and ARM243A. The F1 crosses were studied by visual observation to identify the maintainer/ restorer reaction. The performance of inbred lines and maintainer/ restorer reaction is given in following table. All the inbreds except DRSI-305 restored fertility in CMS 234A and all the inbreds except DRSI-100 and 305 restored fertility in ARM 243A. Partial restorer reaction was indentified for inbred DRSI-160 in both the CMS lines.
