Twenty-eight established groundnut mutants and two check cultivars were studied during Kharif-I (March-June) season of 2017 and 2018 to find out their variability and distinct character(s) as identifying keys. All the mutant lines showed erect type sequential branching habits with two seeds in each pod although they had shown significant variability in all vegetative and reproductive structures. According to cluster analysis, 30 mutants/varieties clustered into three major groups at distance level 60 based on the morphological variability of 14 characters. The variability of 14 morphological characters in three principal components was explained by 98.12% of the total variation. The characters, 100-pod weight had the highest contribution followed by branch length, plant height and 100-kernel weight. Twenty-three mutant genotypes grouped into intermediate type of the extremes in any given identifying key characteristics. Only single genotype of the whole lot showed distinctively the longest primary branch and highest secondary branch number and small seed size (D1/24-29), highest primary branch number (M6/7-25), lowest primary branch number (Mut-2), highest leaflet length and light green leaf colour (Dhaka-1), presence of stem pigmentation and pod beak and highest number of seeds pod-1 (Zhingabadam), leaflet shape lanceolate (M6/54-20). In contrast, only two mutants of the lot showed two buds raceme-1 (M6/36-24 and M6/61-6), bolder pod and seed size and highly constricted pod (Mut-2 and Mut-3). The genotypes with the above distinguished characteristic featured for being ideal genetic markers and could be used in future breeding applications as well as aids in varietal identification.

FloRunTM ‘331’ peanut variety was developed by the University of Florida, Institute of Food and Agricultural Sciences, North Florida Research and Education Center near Marianna, Florida.  It was released in 2016 because it combines high yield potential with excellent disease tolerance. FloRunTM ‘331’ has a typical runner growth habit with a semi-prominent central stem and medium green foliage.  It has medium runner seed size with high oleic oil chemistry.

Seed size is an important trait in common bean. The objective was to identify RAPD markers associated with QTL for seed weight, seed length, and seed height in a molecular marker-based linkage map in a recombinant inbred (RI) population from the common bean cross of the larger seeded (100 seed/39 to 47 g) PC-50 (ovate seed shape) × smaller seeded (100 seed/26 to 35 g) XAN-159 (flat rhomboidal seed shape). The parents and RI lines were grown in two separate greenhouse and two field (Wisconsin, Dominican Republic) experiments using a RCBD. Continuous distributions for seed weight, seed length, and seed height were observed for RI lines indicating quantitative inheritance. One to three QTLs affecting seed weight explained 17% to 41% of the phenotypic variation. Two to three QTLs for seed length explained 23% to 45% of the phenotypic variation. One to four QTL associated with seed height explained 17% to 39% of the phenotypic variation. A RAPD marker M5.850 in linkage group 3 was consistently associated with seed weight, seed length, and seed height in all experiments and explained 7% to 13% of the phenotypic variation for these traits. A seedcoat pattern morphological marker (C) in linkage group 1 was associated with seed weight and seed height in two greenhouse experiments.
