Overcome The Incompatibility of Peanut Interspecific Hybridization
Application of regulators to overcome interspecific incompatibility in peanut hybridization
Gibberellic acid and kinetin
In order to increase the fertilization frequency of incompatible hybridization and promote the development of peanut pods, the female parent plants were emasculated, and the fresh male parent pollen was collected in the early morning of the second day. At the ovary at the base of the peanut style, the average needle extraction rate was 14.2% to 33.3%, the fruit needle lengthened 8.7cm, and the ovary expansion rate was 75%. After 20 days, the fruit needles were treated with 100 mg/L auxin liquid, and the ovary enlargement rate reached 87.2%. After another 15 days, the pods were treated with 10～50mg/L furfuraminopurine (kinetin) solution, which could promote the formation of pods, and the pod formation rate was 12.5%～65.1%.
