Presence of physical barrier or mechanical obstacles between the anther and stigma ensures cross pollination. Papaya, hemp, date, palm, etc. Cross-pollination is the most advantageous of the two types of pollination since it provides species with greater genetic diversity. pollination. ea�ha`dap`X��!��;��i���xXw2�Q��5 ���ld�94aZ�I�m���rTh� ��8,ti�T���,�,�őҳ��c1��>G��@)��M<7��qLh�x"�Ь�Cq�A(*@��80�p� l���N@Z�5�e�cz�1��ET�Gl�K���}����cC$�H� 0x�00<>����X�p��� ��y��j0�Y������3f�M ٚ`� endstream endobj 81 0 obj 260 endobj 43 0 obj << /Type /Page /Parent 39 0 R /Resources 44 0 R /Contents [ 50 0 R 52 0 R 61 0 R 63 0 R 65 0 R 67 0 R 71 0 R 73 0 R ] /MediaBox [ 0 0 612 792 ] /CropBox [ 0 0 612 792 ] /Rotate 0 >> endobj 44 0 obj << /ProcSet [ /PDF /Text ] /Font << /F1 46 0 R /F2 68 0 R /F3 47 0 R /F4 58 0 R /F5 56 0 R /F8 55 0 R >> /ExtGState << /GS1 76 0 R >> >> endobj 45 0 obj << /Type /FontDescriptor /Ascent 715 /CapHeight 690 /Descent -234 /Flags 34 /FontBBox [ -170 -240 996 935 ] /FontName /IKLPHB+TimesTen-Roman /ItalicAngle 0 /StemV 88 /XHeight 470 /CharSet (/percent/quoteleft/two/at/d/s/R/endash/three/ampersand/b/t/S/B/grave/fou\ r/c/C/quoteright/u/U/acute/five/e/D/V/parenleft/v/circumflex/six/f/E/w/W\ /parenright/seven/T/h/F/y/X/asterisk/eight/i/G/z/Y/nine/j/H/Z/I/x/g/comm\ a/J/colon/k/bracketleft/m/hyphen/L/semicolon/A/dieresis/n/M/period/brack\ etright/o/N/slash/a/p/l/O/zero/q/P/one/K/question/Q/r) /FontFile 75 0 R >> endobj 46 0 obj << /Type /Font /Subtype /Type1 /Name /F1 /FirstChar 32 /LastChar 251 /Widths [ 250 333 500 500 500 1000 833 278 389 389 500 600 250 333 250 278 500 500 500 500 500 500 500 500 500 500 250 250 600 600 600 500 800 838 722 722 833 722 611 833 833 389 444 778 667 944 778 833 611 833 778 556 667 833 778 1000 778 778 722 333 278 333 600 500 278 500 556 444 556 500 333 500 556 278 278 556 278 833 556 556 556 556 389 389 333 556 500 722 500 500 444 333 222 333 600 250 250 250 250 250 250 250 250 250 250 250 250 250 250 250 250 250 250 250 250 250 250 250 250 250 250 250 250 250 250 250 250 250 250 333 500 500 167 500 500 500 500 278 500 500 333 333 556 556 250 500 500 500 250 250 600 500 278 500 500 500 1000 1000 250 500 250 278 278 278 278 278 278 278 278 250 278 278 250 278 278 278 1000 250 250 250 250 250 250 250 250 250 250 250 250 250 250 250 250 1000 250 300 250 250 250 250 667 833 1000 334 250 250 250 250 250 667 250 250 250 278 250 250 278 556 778 556 ] /BaseFont /IKLPHB+TimesTen-Roman /FontDescriptor 45 0 R >> endobj 47 0 obj << /Type /Font /Subtype /Type1 /Name /F3 /FirstChar 32 /LastChar 251 /Widths [ 250 333 500 500 500 1000 833 278 389 389 466 600 250 333 250 278 500 500 500 500 500 500 500 500 500 500 250 250 600 600 600 500 800 778 722 722 833 722 611 833 833 389 444 778 722 944 778 833 667 833 722 556 667 778 722 944 778 722 722 389 278 389 600 500 278 500 556 444 556 444 333 500 556 278 278 556 278 833 556 556 556 556 389 389 278 556 500 722 500 500 500 389 222 389 600 250 250 250 250 250 250 250 250 250 250 250 250 250 250 250 250 250 250 250 250 250 250 250 250 250 250 250 250 250 250 250 250 250 250 333 500 500 167 500 500 500 500 278 500 500 333 333 556 556 250 500 500 500 250 250 600 500 278 500 500 500 1000 1000 250 500 250 333 333 333 333 333 333 333 333 250 333 333 250 333 333 333 1000 250 250 250 250 250 250 250 250 250 250 250 250 250 250 250 250 944 250 300 250 250 250 250 722 833 944 334 250 250 250 250 250 722 250 250 250 278 250 250 278 556 722 556 ] /BaseFont /IKLPID+TimesTen-Italic /FontDescriptor 48 0 R >> endobj 48 0 obj << /Type /FontDescriptor /Ascent 715 /CapHeight 690 /Descent -234 /Flags 98 /FontBBox [ -169 -225 1015 928 ] /FontName /IKLPID+TimesTen-Italic /ItalicAngle -15 /StemV 85 /XHeight 465 /CharSet (/comma/six/m/hyphen/W/d/seven/n/y/X/period/M/b/o/N/eight/z/l/c/p/x/Z/nin\ e/O/zero/e/q/P/D/one/f/r/E/K/two/h/s/F/three/A/i/t/G/a/S/u/g/I/v/V) /FontFile 78 0 R >> endobj 49 0 obj 1051 endobj 50 0 obj << /Filter /FlateDecode /Length 49 0 R >> stream High genetic identity between wild and domesticated forms suggests that wild Bambara groundnut is the true progenitor of domesticated Bambara groundnut. (1998). sec is governed by a single gene. 3. H�c```�clž� �� In some species, flower open but only after pollination has taken place. 1) Autogamy or self pollination and 2) Allogamy or cross pollination.

Pollination is the transfer of pollen from a male part of a plant to a female part of a plant, later enabling fertilisation and the production of seeds, most often by an animal or by wind. H�]U�r�8}�W�ў���5o�s�Ɖ�q��l�@ˌōLyD)���$(��d� ��ftvMl�F9ɣ,��$xJ��)�H&��0 In cross pollinated species pollination may be brought about by wind, water insect or animals. autogamy or self pollination. The haploid gametophyte is small and nutritionally dependent on the sporophyte. After pollination and fertilization above ground the developing pegs grow downward (toward gravity), penetrating the soil, each peg with an immature peanut pod (ripening ovary) at its tip. The reach of pollen over the stigma is called pollination. It is transfer of pollens from and to the stigma within the same flower , is always found in bisexual flower. E.g Maize, Cucurbit, Strawberry, etc. large number of pollen grains are produced by plants using abiotic mode of pollination as most of pollen grains are wasted during transfer. Autogamy is the closest form of inbreeding. Groundnut Beans (some) Cowpea Sunflower Melon Cucumber Squash, marrow Eggplant Cabbage Onion ...

Often in breeders are found at the extremes of the species distribution in marginal habitats and […] Anther and stigma of hermaphrodite flower mature at different time, facilitating cross pollination. In most of the cross pollinated sp. �PR�9 ,ꪒE���{�e� A pollen tube grows down to permit the male gamete to fertilize an egg and make a seed . Example of self pollinatedplants is Rice, Wheat, Tomato,Okra, Peanut, Potato, etc. In the peanut, the diploid sporophyte phase is the more dominant of the two phases. Bajara, maize, sunflower, alfalfa, castor, cross pollination is not complete and self pollination may occurs 5-10%. Plant Breeding, 117(3), 255–260. Self-fertilization, where pollen from a plant will fertilise reproductive cells or ovules of the same plant; Cross-pollination, where pollen from one plant can only fertilize a different plant; Asexual propagation (e.g. 3) Usually hybrid and syntheticwitout reducing heterozygosity. selfing mode of pollination in both wild and domesticated Bambara groundnut. Self‐pollination resulted in more fruit abortion and produced fruits that were mis‐shapen, curved with lower numbers of arils/locule, arils/fruit and lower numbers of seeds which were usually shrunken and disfunctional. ��o��� �&�����)c�d��(�ݑ�)Mf�S�������j2�,?���W_p����s-���~e �=��y�O�o���1 Rʆ�iL�,ų��1��*��������ޡ�&/�YU�f�4OC/ޙ���A��XW���9��Q�,�c�����N�v��nUE�dU�K���2Ƌ�Z}x�� �'a�E[���_\(aq0���gs �բ�QM�qh=v�hU� ���:��Xt��F��6�>�hy ~�7�I�1E[w?����Ji>8"�e+��h��A���7���I؋���P�'�# �! To work out the mode of pollination in a given crop and extent of natural out-crossing.Prediction of performance of double cross hybrids. Pollination is a critical link in the functioning of ecosystems, and it improves the yield of crops. a) Monoecy:   Staminate and pistilate flowers occur in the same plant either in the same inflorescence. The vegetable oil is rich in omega-3 fatty acid and extensively used for cooking purpose. selfing mode of pollination in both wild and domesticated Bambara morphological variation. Zebrowska, J.

Pollination as a key factor for strawberry fruit physiology and quality. ii) Self pollinated species do not show inbreeding depression, exhibit considerable heterosis. In this condition flowers does not open at all and ensure complete self pollination e.g Oat, Barley, Wheat, Grasses, etc. marigold, maize, cotton, etc. In this type plants are self pollinated, however the extent of cross pollination often exceed 5 to 50 % such species are generally known as often cross pollinated species.
