ICAR-Indian Institute of Oilseeds Research (ICAR-IIOR), Hyderabad has developed DSH-185, the first public sector CGMS-based safflower hybrid seed. It has been released and notified for all India cultivation. DSH-185 is a cross between A-133 (CGMS line) x 1705-p22 (a restorer line). Wild species, Carthamus oxyacantha is the source of cytoplasmic genetic male sterility in A-133, the research institute has said.
On an average, DSH-185 gives the seed yield of 14.3 quintal per hectare under rainfed, 21 quintal per hectare under irrigated conditions and 17.4 quintal hectare at national level. It gives the oil yield of 4.12 quintal hectare under rainfed, 5.7 quintal hectare under irrigated conditions and 4.89 quintal hectare at national level. On an average, DSH-185 exhibits 25-30 percent superiority in seed yield over the best check varieties, A1 and PNBS-12 and 15.2 percent superiority over the GMS-based national hybrid check, NARI-H-15. It has 28-29 percent oil content and recorded 25-28 percent superiority in oil yield over A1, PNBS-12 across test locations, ICAR-IIOR has claimed.
The potential of DSH-185 vs. variety has been demonstrated in farmers’ fields under dry and irrigated conditions in Maharashtra, Madhya Pradesh, Telangana and Chhattisgarh. DSH-185 recorded on an average, 17 quintal per hectare seed yield under dry conditions in Chhattisgarh as against 5 quintal per hectare seed yield of check variety, A1. In Maharashtra, it gave 21 quintal per hectare against 16 quintal per hectare yield of variety, A1 under irrigated conditions while in Telangana, DSH-185 gave 10-14 quintal per hectare against 4-5 quintal per hectare of state variety, Manjira under dry conditions. It is resistant to Fusarium wilt which is the major disease of safflower, ICAR-IIOR has further informed.
Seed production technology of DSH-185 and A and B lines has been perfected. ICAR-IIOR has further conducted training programmes for DSH-185 seed production.
