The experiment was conducted to assess efficiency of pollen storage methods in sunflower by using the parental lines of sunflower hybrid APSH-66. The trial was laid out in a randomized block design with three replications and eight treatments. Analysis of variance revealed that treatment effects were significant for characters such as number of filled seeds per head, seed set (%), seed husk ratio and seed yield per plant. Among the treatments studied, the seed set was more when pollination was done with fresh pollen followed by pollen stored under -200C and pollen stored in refrigerator for different storage periods. Though percent seed set and number of filled seeds per head were significantly higher when fresh pollen is used for pollination, it was statistically on par with pollen stored at -200C for 3 days. Pollen stored in room temperature showed less viability compared to other treatments and this resulted in reduction of number of filled seeds per head and seed set (%). Effect of pollen storage methods on seed quality parameters showed significant differences between the treatments for all the traits studied except germination percentage. Seedling vigour index was found to be significantly superior when fresh pollen was used for pollination but it was on par with the treatments, pollen stored in refrigerator for 3 days and pollen stored at -200C for 3 days. Based on the study it is suggested that in case of scarcity of pollen during pollination in hybrid seed production, pollen grains may be stored in -200C or in refrigerator and could be utilized effectively.
