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. | Pollen storage and pollination studies for maximization of hybrid seed production in sunflower Helianthus annuus L.
