Runner cultivars are widely demanded by peanut farmers because of their high oil and grain productions. As those are late cycles, the management is limited in environments with water restriction. For improvement of runner genotypes to these environments is necessary to identify genotypes adapted and the knowledge of genetic divergence is quite relevant to assist the breeding procedures. In this work, ten morphological and agronomic traits were measured on 13 runner peanut genotypes grown in sandy loam textured soils during the rainy season in three environments on Brazilian Northeast region. These measurements included harvest index (%), main stem height (cm), 100 seed weight, 100 pod weight, pod length (mm), number of pod/plant, blooming (days after emergence, dae), number of seed/plant, physiological maturation of pods (dae) and oil content in seeds (%). The genetic divergence of genotypes was estimated by multivariate methods. Data set was analyzed by canonical variable (CV) in combination with UPGMA-clustering analyses. The statistical analysis was performed using the GENES program. We found that the first two CV were significant and accounted for 82.13% of the total variation. Three groups were clearly formed, separated by earliness and pod production. This arrangement was further attested by the dendrogram generated by UPGMA. The CV indicated that physiological maturation of pods, main stem height, number of pods/plant and 100 seed weight were the most differentiating traits among the genotypes. These two last allowed high magnitude associations and were contributive to selection procedures in improvement works. We provide indications of the best genotypes with potential to generate robust progenies, in a peanut breeding program.

<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>

The study aimed to analyze a varied collection of 371 germplasm obtained from various countries, with regards to yield-related characteristics, oil, protein, sugar, free amino acids, and total phenolics, in two distinct environments. The purpose was to assess the extent of inherent genotypic diversity and the potential for improving productivity and quality through breeding. The study identi ed germplasm that exhibited superior and stable performance with two or more desirable traits. Speci cally, NRCGs-10366, 10480, 10485, and 10844 were found to be superior in terms of yield (PY), hundred kernel weight (HKW), and seed shape (SHP). NRCG-11390 was identi ed as superior for yield (PY), protein content, and sugar content. Additionally, NRCGs-12469, 14089, and 16492 were found to be superior for important biochemical traits such as oil, protein, and sugar content. NRCG-11101 was identi ed as superior for HKW, protein content, and oil content, while NRCGs-11154 and 11164 were found to be superior for HKW, protein content, and sugar content. The study has identi ed germplasm with a grain protein content exceeding 34% and an oil content ranging from 47% to 48%. Germplasm exhibiting speci c traits were identi ed for their potential utilisation as donors in the groundnut improvement program. The Spanish collection presents a potential source of valuable breeding traits for enhancing groundnut productivity and improving the content of oil, protein, sugar, phenol, and FAA, in various combinations.
