Abstract
The present article pertains to the pollen vitality and germination capacity of 3 Brassica taxa viz. B. rapa ssp. campestris (L.) Clap, B. oleracea var. capitata L., and B. oleracea var. botrytis L. The study revealed that B. oleracea var. botrytis showed vitality for a longer period of 128 weeks at freeze-dried condition (-60 C), while the shortest period of 32 weeks was noted in B. oleracea var. capitata. In fresh form pollen of B. oleracea var. botrytis showed 72% of germination compared to 64% and 62% of B. oleracea var. capitata and B. rapa ssp. campestris respectively. In stored conditions the maximum percentage of germination (74.5%) was noted in B. rapa ssp. campestris after 4 weeks of storage compared to the lowest (10.7%) of B. oleracea var. capitata. The investigation showed that the freeze-dried condition seemed to be a better method for pollen storage contrary to the refrigerator (4ËšC) and freezer (-20ËšC, -30ËšC).
