Abstract : The effect of different modes of pollination on
quantitative and qualitative parameters of Egyptian clover, Trifolium
alexandrinum L. was studied at Forage Section, Department of Genetics and
Plant Breeding, CCS, Haryana Agricultural University, Hisar during 2012 and
2013. Maximum seed setting (81.5%) was recorded in A. mellifera
pollination with an 8 frame colony (BP-8F) followed by 4 frame colony (BP-4F)
(75.1%), open pollination (OP) (73.8%) and 2 frame colony (BP-2F) (71.5%).
Maximum seed yield (2662.3 seeds) was observed in treatment BP-8F followed by
BP-4F (2373.8), OP (2316.3) and BP-2F (2235.5). Still lower yield of 2103.0
seeds was found in hand pollination (HP) treatment that was significantly higher
than the without insect pollination (WIP) treatment (1114.2). Minimum 1000-seed
weight was observed in WIP (2.64 g). The seed weight of BP-4F (3.30), HP (3.20),
BP-2F (3.17) and OP (3.03), the heaviest seeds were recorded in BP-8F (3.62
g/1000 grains) and it was at par with the treatment BP-4F (3.30 g). Highest seed
germination per cent was recorded in BP-8F (94.7) followed by OP (90.7%). Lowest
germination was found in WIP (84.7%). Though some work has been done on this
aspect in India but comprehensive pollination studies has not been worked out.
