Peanut legumes have the peculiar habit of ripening underground, a phenomenon known as geocarpy.After pollination and the withering of the flower, an unusual stalklike structure called a peg grows from the base of the flower toward the soil. The peanut embryo consists Of a hypocotyl . The peanut peduncle, or peg (the stalk that holds the flower), elongates after flower fertilization and bends down into the ground, where the peanut seed matures. At the base of ovary, a meristematic region grows and becomes a stalk like structure (gynophore) that bends downwards and forces the ovary into the soil. Flowers are presented as papilionaceous racemes. Peanut growers call this elongation of the peg "pegging." As the peg elongates, a cap of cells forms next to the withered style. Hypanthium length.

Several flowers can originate from each node, however, only about 15 to 20 percent will produce a harvestable pod. Soils with a high clay percentage . Since yield is limited by biotic and abiotic stresses, newer cultivars with tolerance to these stresses are needed to optimize yield. Ren et al. Each oblong anther contains four loculi and each globose anther two. The main axis is a flattened, more or less convex structure, the receptacle, on which the florets (small flowers) are arranged in a centripetal order. Most of the genotypes used in this study showed resistance to rust and LLS diseases except three genotypes (ICGV-SM 16585, ICGV-SM 16587 and ICGV-SM 16575), which showed comparable susceptibility to the susceptible check (Pendo 98). Vigna subterranea, the Bambara groundnut. helps retain moisture, improves soil structure, and benefits soil microorganisms. The peanut (Arachis hypogea) is a dehiscent legume that is harvested from below the soil.The legume was originally formed above ground following pollination. Peanut seeds (kernels) grow into green oval-leafed plants about 18 inches tall, which develop delicate yellow flowers around the lower portion of the plants. This specialized structure .

Seed coat protects the seed from physical . grouped 196 accessions of groundnut in 5 groups for both cluster and structure analyses. Soil and Climate for Groundnut cultivation: Groundnut does well in the light-textured, loose, friable, well-drained, and sandy and sandy loam soils which facilitates easy penetration of pegs and their development along with harvesting.Clay and heavy soils are not recommended for this crop as they interfere in penetration of pegs and make harvesting very difficult. The reproductive parts of a flower consist of the following: Stamen: This is the male reproductive organ and is also known as Androecium. Success rate of hybridization could also be affected by the flower integrity. A flower may have only female parts, only male parts, or both. Micropyle: It is a tiny pore in the testa that lies on the opposite of the tip of the radicle. Plant morphology refers to the study of external form and structure of plants. The whole inflorescence is surrounded by an involucre (a whorl of bracts) and bears only one or two types of flowers: inner disc florets and outer ray florets. . Groundnut Cultivation. studied the phenotypic variability of Bambara groundnut accessions from northern Burkina Faso, and reported that the plant canopy, number of pods per plant, seed width, seed length, seed weight per plant and a 100 seed weight were positively correlated with seed yield per plant. However optimal yields are produced when drought stress is avoided and extreme temperatures are minimized during the critical 60 - 100 DAP interval.

Peanut (Arachis hypogaea L.) is an important food and oilseed crop in the United States and worldwide with high net returns.However, input costs are high (US$1,970-$2,220 ha −1), and yield in excess of 4,500 kg ha −1 is needed to offset the costs. Heads can be determinate or indeterminate. plasm, the site for cell division and thus for plant growth and development. Example: pea, groundnut. One flower may contain the pistil and stamen, as in beans, or they may occur in different flowers, as in corn. It is a common theme in plant genome structure that a relatively few transposon species are present at high number, and many more are present in low numbers.
