tailieunhanh - Pollen storage and pollination studies for maximization of hybrid seed production in sunflower (Helianthus annuus L.)

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.
