A gene LBA5 for regulating lateral shoot angles, growth habits, and a plant architecture of Arachis hypogaea L., and use thereof are provided. In the present disclosure, a major gene LBA5 for controlling lateral shoot angles, growth habits, and a plant architecture of Arachis hypogaea L. is mapped and cloned from Arachis hypogaea L., which includes two homologous genes LBA5b and LBA5a and promoters thereof. The allelic variations of the gene can be selected through crossbreeding and backcrossing to achieve the genetic improvement on an angle between an Arachis hypogaea L. lateral shoot and a main stem. Through a genetic engineering operation for the gene and a change for a promoter sequence of the gene, the function or expression level of this gene in a procumbent Arachis hypogaea L. variety can be adjusted to further regulate an angle between an Arachis hypogaea L. lateral shoot and a main stem.

Cloning and use of an Arachis hypogaea L. flowering habit gene AhFH1 and allelic variants thereof are provided. Through experiments, the Arachis hypogaea L. flowering habit gene AhFH1 and two defunctionalized allelic variants thereof are determined. The defunctionalized allelic variants can cause the change from alternate flowering Arachis hypogaea L. to continuous flowering Arachis hypogaea L. Through overexpression of the gene AhFH1 or supplementary expression of a promoter of the gene itself, a continuous flowering Arachis hypogaea L. variety can be changed into alternate flowering Arachis hypogaea L.; and through knockout or expression suppression of the gene AhFH1, alternate flowering Arachis hypogaea L. can be changed into continuous flowering Arachis hypogaea L. Marker-assisted selection (MAS) breeding is realized for allelic variants of the gene using molecular markers.

Herein provided is a new runner-type peanut variety designated ‘Georgia-18RU’ as well as the seeds, plants and derivatives of the new peanut variety ‘Georgia-18RU’. Also provided are tissue cultures of the new peanut variety ‘Georgia-18RU’ and the plants regenerated therefrom. Methods for producing peanut plants by crossing the new peanut variety ‘Georgia-18RU’ with itself or another peanut variety (such as another runner-type peanut variety) and plants produced by such methods are also provided. ‘Georgia-18RU’ is a unique runner-type peanut cultivar having a combination of high level of tomato spotted wilt virus (TSWV) resistance and leaf scorch resistance caused by Leptosphaerulina crassiasca (Séchet) Jackson and Bell, and high yield. ‘Georgia-18RU’ provides a medium maturity runner-type peanut cultivar with a prominent main stem, medium green foliage, medium-large runner seed size, and pink seedcoat color.

Herein provided is a new runner-type peanut variety designated Georgia-SP/RKN as well as the seeds, plants and derivatives of the new peanut variety Georgia-SP/RKN. Methods for producing peanut plants by crossing the new peanut variety Georgia-SP/RKN with itself or another peanut variety (such as another spanish, valencia, virginia, or runner-type peanut variety) and plants produced by such methods are also provided. Georgia-SP/RKN is a unique spanish market-type peanut cultivar having a combination of a high level of resistance to peanut root-knot nematode (RKN) (Meloidogyne arenaria) and a high level of resistance to tomato spotted wilt virus (TSWV), high yield and high-oleic fatty acid content of seed oil. Georgia-SP/RKN provides a medium plus maturity spanish market-type peanut cultivar with intermediate decumbent runner growth habit, tan testa color, and large spanish market-type seed size.

The present disclosure is directed to methods of genetically detecting or generating a peanut line that is resistant to peanut smut infection. The disclosure also relates to cultivation of smut resistant peanut lines and the cessation or prevention of peanut smut in a given geographic area.

The present invention relates to new reduced-fat peanut products and plant lines, including peanut plants, seeds, varieties, and hybrids. The invention further relates to peanut seed having a reduced-fat content of from about 27.9% to about 39.57% and to novel peanut plants and lines which produce seeds having a reduced-fat content of from about 27.9% to about 39.57%. The invention also relates to methods for producing a peanut plant which produces seeds having a reduced-fat content of from about 27.9% to about 39.57% containing in its genetic material one or more transgenes and to the transgenic plants produced by those methods. This invention also relates to peanut cultivars or breeding cultivars and plant parts derived from peanut plants which produce seeds having a reduced-fat content of from about 27.9% to about 39.57% and to methods for producing other peanut cultivars, lines or plant parts derived from peanut plants which produce seeds having a reduced-fat content of from about 27.9% to about 39.57%.
