Not AvailableTwo CMS-based safflower hybrids viz., DSH-249 and DSH-250, evaluated at multilocations for two consecutive years under rainfed and irrigated conditions, exhibited 14 and 29% superiority over the national check hybrid, NARI-H-15 for seed yield and 17 and 29% superiority for oil yield. Both hybrids were found resistant to Fusarium wilt; DSH-249 possessed higher oleic content (35%).Not Availabl

Not AvailableFusarium wilt caused by Fusarium oxysporum f sp. Carthami Klisiewicz and Houston is a major disease in safflower. Sources of resistance to Fusarium wilt among the vast collections of safflower germplasm were very few. The multiple crossings effected between susceptible high yielding lines and the wilt resistant breeding lines resulted into identification of several wilt resistant lines. Among them, six lines found to be stable for wilt resistance (<20% wilt incidence) over years of screening in wilt sick plot. These lines have exhibited 73-105% superiority in seed yield and 88-139% superiority in oil yield over the high yielding national check variety, A1 when tested in the research farm of the Directorate of Oilseeds Research, Hyderabad. One of these entries viz., DSI-101 when tested for yield performance at 19 locations in Initial Varietal Trial (IVT) of AICRP (Safflower), recorded 18.3% higher seed yield and 26% higher oil yield over the highest yielding national check variety, A1 under irrigated conditions and 2.7% higher oil yield over A1 and near on par with A1 with respect to seed yield under rainfed conditions. It also exhibited resistance to Fusarium wilt in multilocation wilt sick plots in IVT.Not Availabl

Not AvailableMolecular breeding plays an important role in sustainable agriculture development. Hybrid rice technology aims to increase the yield potential of rice beyond the level of inbred high-yielding varieties (HYVs) by exploiting the phenomenon of hybrid vigour or heterosis. Improvement of hybrid rice parental line is necessary to meet the food security problem. Parental polymorphism was carried with 215 SSR markers between five recurrents and ten donors. During the foreground selection, both reported markers (S5-Indel and BF-S5) were validated for wide compatibility, 2 out of 14 (ART5 and SC3) validates for submergence tolerance, one out of two (RM5) validate for stigma exsertion, whereas 2 of 3 markers (RM5970, RM3476) validated for elongated uppermost internode traits between recurrents and donors. For background selection, maximum polymorphic markers (112) between IR58025eB i.e improved maintainer line with elongated uppermost internode and Oryza meridionalis and minimum polymorphic markers (42) between IR79156B and IR91-1591-3 were found. Marker-assisted backcrossing accelerate, the transfer of gene of interest in desirable genetic background. Genotypes IR58025B and IR58025eB emerged as genetically most similar with a value of 97%. The genotypes IR64 Sub1and Oryza meridionalis were found most divergent showing 33% genetic similarity. Dissimilarity coefficient of the generated information obtained on genetic relatedness would be supportive in further rice breeding program.Not Availabl
