Abstract:

Sunflower (Helianthus annuus L.) is one of the principal oil seed crops of the world. Deterioration in seed quality is reflected in terms of loss in vigour and viability of seeds. Therefore, seed viability and vigour largely depends on the storage conditions, seed treatment and packaging materials used to store the seeds. With this background storage experiment was carried out in laboratory of Department of Seed Science and Technology in two factorial completely randomized design to assess the quality of four sunflower genotypes such as RSFH-130, RSFH-1887, KBSH- 53 and KBSH- 44 which were stored in two different packaging materials such as cloth bag and polythene bag (700 guage) for a period of 10 months and observation were taken bimonthly. In the present study the results revealed that RSFH- 1887 and stored in polythene bag maintained highest germination (80.25 %) and vigour (1559) respectively which was followed by KBSH-53 stored in polythene bag maintained germination (79.85 %) and vigour (1518) at the end of 10th month. Whereas, KBSH - 44 stored in polythene bag was intermediate storer which showed germination of (77.76 %) and vigour (1430) at the end of 10th month. While, RSFH- 130 stored in cloth bag was found to be a poor storer which showed reduced germination (57.26 %) and vigour (907) compared to other genotypes at the end of 10th month. Whereas, electrical conductivity was found to be less in RSFH-1887 stored in polythene bag (0.72 dSm-1) and highest EC was found in RSFH-130 stored in cloth bag (0.85 dSm-1) since it is inversely proportional to seed quality. However, the seed stored in cloth bag showed less germination and vigour compared to polythene bags irrespective of genotypes. It can be concluded that RSFH- 1887 stored in polythene bag maintained high seed quality. Thus the experiment helps in identifying best genotype among the above four genotypes and best container for better storability.
