Hence, the crop can be classified as often cross pollinated. Wheat crossing kit . Groundnut flowers are typically papilionaceous and zygomorphic with a reduced pedicle. Genetic studies assist the breeder in understanding the inheritance mechanism and enhance the efficiency of a breeding program. From the selected inflorescence all the male flowers are removed and the female flowers protected with a suitable cover. The flower bud is gently Learn more. Consuming groundnut is very beneficial for our health. What appears to be a pedicel is actually an elongated hypanthium. Mature flower buds which are ready to open in the next day are selected and emasculated in the evening.  They can be easily identified by the size and length of calyx tube.  The flower bud of groundnut is of crescent shape, being bulged on one side and slightly depressed on the other.  The keel petal is located on the bulged side and the standard is present on the depressed side.  For emasculation, hold the bud between the thumb and the index finger of the left hand and with the help of a razor blade in the right hand, make a cut on the depressed side at two-thirds the length below the tip so as to cut the standard and a portion of the wing petals.  Then gently pull the calyx and corolla by holding at the tip of the flower bud.  By doing this, the sepals and the petals except the keel would be removed, with the help of the fine forceps gently liberate the bundle of stamens and the pistil from the keel and nip off the anthers.

The cultivated groundnut, a native of South America, is regarded as a self-pollinated leguminous crop (normally with less than 1% cross- pollination), but cross-pollination up to a maximum of 10% has been reported ,resulting in natural hybridization. The flower bud which is expected to open in the next day morning is selected in the previous day evening between 3 P.M. and 6 P.M. and emasculated by just removing the corolla tube in which the stamens are attached. The crop produces self-pollinated papilionaceous flowers for the crossing of which hand emasculation and dusting are the best methods employed. 5) Emasculation and hybridization techniques in self pollinated crops : Green gram, Black gram, Rice, Wheat, Groundnut, Soybean. On a bright clear day, the flowers open between 5 and 7 am.  In the mature flower bud, just before the flower opens, the four unripe anthers are much below the stigma which at this stage is not receptive.  The anthers begin to burst longitudinally after 4am in the next day and commence to liberate their pollen.  At this time, the stigma becomes receptive.  The plant comes to flowering 4 weeks after sowing.Â. One such factor is hybridization. H&H Creations Recommended for you. Health benefits of groundnut seeds.
