Inflorescence: Racemose- terminal or axillary raceme; Cymose- solitary in Solanum. Finger millet grains can be stored f, years without being infested by storage pest, whic, a prefect food grain commodity for famine pron, for assured crop harvest in low input agro-. was also found eff, inducing male sterility under hill condition in barnyard, Small millets are highly self-pollinated and relatively low, level of improvement in small millets appears to be the con-, sequence because of difficulties in emasculation and hyb-, ridization. Flowers may promote selfing, i.e., the union of sperms and eggs from the same flower, or cross-fertilization, i.e., the union of sperms and eggs from different flowers. The anth, The glumes open for a short while and self pollination is the. Their study revealed that when stigma, comes out of the lemma, it is covered with a thick cloud of, pollen dust due to association of elongation of style and, allows any chance for cross pollination. By continuing you agree to the use of cookies. Controlled pollination experiments designed to evaluate seed set (%) demonstrated that T. crinita is self-compatible, whereas results from morphological and simple sequence repeat (SSR) marker analysis of progenies revealed lack of outcrossing. Two parental lines of finger millet, PR 202 and IE 2606, were used for reciprocal crossing. long and short pedi-, celled (Nanda and Agrawal 2008). Cajanus cajan (Pigeon pea) Pisum sativum (Pea) Vicia faba (Broad bean) Cicer arietinum (Gram) Phaseolus aureus (Green gram) Oil-yielding plants. (1997) Foxtail millet in Indian agriculture. The, inflorescence of grass family has been mu, study of the grasses as a source of diagnostic character for, the identification and its phylogenetic value (V, In grasses, the spikelet is the unit of the inflorescence, small bract leaves called glumes and their enclosed floret, ous, are arranged in spikelets and enclosed in chaffey, (papery) scales (Bor 1960) known as a lemma an, The whole structure including the lemma, the palea and the, flower (carpels, stamens and lodicules) is ref, is one seeded and ovary wall is united with the seed coat, The floret consists of gynoecium, androecium and lodi-, cules. In: Janick J (Ed). Except for finger millet and foxtail millet, and to some extent proso millet and teff, other small millets have received minimal research attention in terms of development of genetic and genomic resources and breeding for yield enhancement. The human body is naturally inhabited by a wide variety of microbes, collectively referred to as normal flora. The timing of anthesis in proso millet between 10.00 a.m, from the start of the anthesis of the first flower to the last, floret on the panicle. The effect of selfing, emasculation and crossing, advocating the removal of petals by the forceps during emasculation, and covering the emasculated bud with a muslin bag. Flower development occurred in 6 distinct stages and took 35 days. Small millets are an excellent choice to supplement major staple foods for crop and dietary diversity because of their diverse adaptation on marginal lands, less water requirement, lesser susceptibility to stresses, and nutritional superiority compared to major cereal staples. Development of lodicule stomata is different than that in leaves. Para o estudo da morfologia e biologia florais, flores e inflorescências foram marcadas e acompanhadas até a formação dos frutos. 112 Floral biology of Cajanus cajan. Offtypes found in farmers' fields where foxtail millet is cultivated were shown to have originated from such interspecific crosses. Lobularia is used for gonorrhoea. 4. (2002) Progress with proso, pearl and other millets. Black gram (Vigna mungo (L.) Hepper) is an erect, fast-growing annual, herbaceous legume reaching 30-100 cm in height. Floral biology Flowering begins 17-35 days after seedling emergence, depending on the cultivar and envi­ ronmental conditions. Finger millet inflorescence is in the whorl of 2-11 digitate, straight or slightly curved spikes. Stand the floral parts. Chickpea, annual plant of the pea family (Fabaceae), widely grown for its nutritious seeds. Progress in crop improvement of foxtail millet has been achieved chiefly through pedigree selection in many parts of the globe. However, spontaneous interspecific hybridizations in the experimental garden occurred in both directions at rates ranging from 0.002% to 0.6% according to plant density and distance between parents. Twelve out of 28 RAPD markers, 4 out of 20 ISSR markers and 21 out of 101 SSR markers showed polymorphism between parental lines. The foxtail millet is highly autogamous and the extent, cultivated and the wild taxa of foxtail millet, derivatives of, increase in grain weight was observed in polyploids, but the, total grain yield decreased by 46% (Siles, Proso millet is a widely cultivated as a cereal crop across, for extreme soil and climatic conditions as it yields rea-, sonably well even in degraded soils under unf, ther conditions (Baltensperger 2002). Noteworthy, the crop is low on glycemic index, gluten-free, possesses good quality protein, vitamins, minerals, and other nutraceutical properties. The racemes are few to numerou, densely crowded at the apex with spikelets arrang, regular rows on the triquetrous rachis. Flowers provide nectar to certain birds and insects, which in turn help in the transfer of pollen from one flower to the other.

Frequency of bat visitation per flower per night was highly variable within and between species of cactus, with average frequencies varying between 27 and 78 visits/flower/night. Understanding floral biology and pollination system helps in devising appropriate emasculation and crossing protocols. With the rapid advancement in molecular systematic and bioinformatic tools, and in conjunction with a wealth of literature available on structural characters, a more refined picture of grass taxonomy and evolution is expected. It has three stamens; anthers are tan or. The present study floral biology and ancillary characteristics of Bambara groundnut used SB-42, Uniswa Red, S-165-A, S-193 and nine isolated gamma irradiated stabilized mutants of SB-42 for this investigation.
