Morphological diversity and relationship among cashew (Anacardium occidentale L) individuals in three districts of Southeast Sulawesi, Indonesia

Abstract

Cashew (Anacardium occidentale L), a species belonging to the family Anacardiaceae, has been cultivated throughout most of Indonesia’s areas and has become a priority commodity in Southeast Sulawesi for years. However, the information about its variation on morphology and relationship among individuals are still limited. This study aimed to determine the morphological variations and relationships among cashew individuals in three districts (Konawe, South Konawe, and East Kolaka) of Southeast Sulawesi. As many as ninety individuals were analyzed on 15 morphological variables for the variations and 47 variables using the complete linkage method based on Gower distance for the clustering. The coefficients of variation were varied on all evaluated variables. The highest was the height of main branches (cm), ranging from 47.32 % to 73.72 %. Meanwhile, nut length had the lowest coefficient of variation (6.75%-7.99%). The individuals were divided into two main clusters with two sub-clusters for each cluster.

Explorando o potencial biológico do hipocarpo de Anacardium occidentale L.: uma revisão sistemática da literatura

“…Em 2020, a área mundial colhida de castanha de caju foi de 7,1 milhões de hectares, com maior concentração na Costa do Marfim (28,6%), Índia (15,7%) e Tanzânia (11,5%) (Brainer, 2022). Na Indonésia, o A. occidentale é cultivado há anos em várias cidades, abrangendo cerca de 506.752 hectares de área cultivada, com produção de, aproximadamente, 135.569 toneladas, sendo considerado como uma das principais mercadorias que fortalecem o desenvolvimento agrícola e econômico do país (Boer et al, 2021).…”

ANALISIS MORFOLOGI JAMBU METE (Anacardium occidentale L.) BERDASARKAN KARAKTER VEGETATIF DI TIGA KABUPATEN SULAWESI TENGGARA

“…Pada penelitian tersebut mengidentifikasi bahwa jambu mete di Sulawesi Tenggara memiliki variasi terhadap bentuk daun, sosok tanaman dan pola percabangan. Penelitian Boer et al (2021) melaporkan keragaman genetik aksesi jambu mete asal Konawe, Konawe selatan dan Kolaka timur bervariasi mulai dari rendah (panjang biji) sampai sangat tinggi (tinggi cabang utama) dan terbentuk dua kluster utama dan setiap kluster terdiri dari dua sub-kluster pada 90 aksesi yang diteliti.…”

Polimorfisme Primer Rapd Pada Tanaman Jambu Mete Asal Tiga Kabupaten Di Sulawesi Tenggara

“…Salah satu informasi penting yang dibutuhkan dalam kegiatan pemuliaan tanaman adalah informasi keragaman genetik serta hubungan kekerabatan antar individu. Penelitian keragaman genetik jambu mete melalui pendekatan morfologi telah dilaporkan oleh Boer, et al, (2021), namun keragaman morfologi yang diperoleh masih sangat dipengaruhi oleh faktor lingkungan. Oleh sebab itu, dibutuhan suatu pendekatan lain untuk memperoleh informasi genetik tanpa dipengaruhi oleh faktor lain.…”
