“…Twenty seeds from each accession were planted in two-row 10-feet long plots in Dawson, GA during 2008 and 2009. 30 Before planting peanut, the land (Dothan sandy loam soil) was used to plant corn−cotton− peanut for crop rotation. The same amount (500 pound/acre) of gypsum fertilizer was applied for both years when peanuts were cultivated.…”

Peanut is an important legume providing products with nutrient dense including mineral nutrition. However, the genetic basis underlying the variations in the mineral composition in peanut is still unknown. Genome-wide association studies (GWAS) of the concentrations of 13 mineral elements combined with coexpression network were performed using a diverse panel of 120 genotypes mainly selected from the U.S. peanut mini core collection. A total of 36 significant quantitative trait loci (QTLs) associated with five elemental concentrations were identified with phenotypic variation explained (PVE) from 18.35% to 27.56%, in which 24 QTLs were for boron (B), 2 QTLs for copper (Cu), 6 QTLs for sodium (Na), 3 QTLs for sulfur (S), and 1 QTL for zinc (Zn). A total of 110 nonredundant candidate causal genes identified were significantly associated with elemental accumulation, which included one high-priority overlap (HPO) candidate gene arahy.KQD4NT, an important elemental/metal transporter gene located on LGB04 with position 5, 413,913−5,417,353.

“…The sample preparation and measurement procedure followed the protocol developed by our laboratory. 12 The total nitrogen content was expressed as a percentage of the sample mass. A protein factor of 5.46 was used to estimate the protein content in peanut seeds (protein % = N % × 5.46).…”

The level of oleic acid in peanut seed is one of the most important factors in determining seed quality and is controlled by two pairs of homeologous genes ( FAD2A and FAD2B). The genotypes of eight F breeding lines were determined as AABB, aaBB, AAbb, and aabb by real-time polymerase chain reaction and sequencing. Fresh seeds were collected from five seed developmental stages and, after drying, were used for chemical analysis. Our results showed that (1) as seeds developed, seed weight, oil content, and oleic acid level significantly increased, whereas four other fatty acid levels decreased, but protein content and another four fatty acid levels did not significantly change, (2) FAD2A/ FAD2B significantly affected fatty acid profiles but not oil and protein contents, and (3) the data were consistent across 2 years. The variability of seed quality traits revealed here will be useful for peanut breeders, farmers, processers, and consumers.

“…Kacang tanah kaya kandungan lemak, protein yang tinggi, zat besi, vitamin E, vitamin B kompleks, fosfor, vitamin A, vitamin K, lesitin, kolin, dan kalsium (Rahmiana & Ginting 2012;Respati et al 2013). Kandungan protein biji kacang tanah merupakan parameter yang menentukan kualitas nutrisi biji dan berkorelasi negatif dengan kandungan minyak biji dan persentase oleat (Santosa 2010;Wang et al 2016). Biji kacang mengandung 40-48% minyak, 25% protein, dan 18% karbohidrat dan vitamin B kompleks (Kumar et al 2014;Santosa 2010).…”

“…Jarak antarklaster dengan jarak Euclidean dapat menentukan adanya perbedaan dan persamaan fenotipe antar dan inter dalam klaster, atau dapat digunakan untuk menduga jauh dekatnya hubungan kekerabatan antaraksesi (Holbrook & Stalker 2003;Singh & Chauwdhary 1983;Wang et al 2016) karakter morfologinya dan semakin jauh jarak dalam klaster maka semakin banyak perbedaan karakter yang dimiliki (Ajay et al 2012;Dwinedi et al 2001;Mukri et al 2014;Singh & Chauwdhary 1983). Jarak tiap klaster dengan lainnya dapat digunakan pada program optimalisasi pemuliaan tanaman untuk dijadikan sebagai tetua persilangan (Idi Garba et al 2015;Silue et al 2016), persilangan antargenotipe yang berbeda jarak yang jauh akan menghasilkan jarak keragaman yang luas (Mukri et al 2014;Vasanthi et al 2015).…”

<p>Penelitian ini bertujuan untuk mengetahui keragaman sumber daya genetik (SDG) kacang tanah berdasarkan karakter morfoagronomis dan kandungan protein biji. Penelitian dilakukan di Kebun Percobaan Cikeumeuh Balai Besar Bioteknologi dan Sumber Daya Genetik Pertanian (BB Biogen) dan Laboratorium Balai Besar Penelitian dan Pengembangan Pascapanen Pertanian (BB Pascapanen), Bogor pada tahun 2013. Sebanyak 240 aksesi plasma nutfah kacang tanah koleksi bank gen BB Biogen digunakan dalam penelitian ini. Hasil penelitian menunjukkan adanya keragaman yang relatif tinggi pada karakter tinggi tanaman, jumlah polong muda, bobot polong per tanaman, dan hasil polong. Hasil analisis klaster menghasilkan 9 klaster. Di antara 9 klaster tersebut, terdapat satu klaster yang beranggotakan sebanyak 221 aksesi, sedangkan klaster yang lain terdiri atas 1-8 aksesi. Terdapat beberapa aksesi yang terpisah dari klaster yang lainnya dan memiliki sifat yang spesifik. Aksesi-aksesi tersebut di antaranya adalah Leuweungkolot (pertumbuhan tanaman tinggi), Tapir-1 (jumlah cabang banyak), Hobotama (jumlah polong isi banyak), Lokal Tretes dan Lokal Subang (hasil polong tinggi), dan Lokal Subang XI (kandungan protein >30%). Aksesi-aksesi dengan karakteristik spesifik tersebut berpotensi sebagai sumber tetua persilangan.</p>
