SIDIK LINTAS KARAKTER VEGETATIF DAN GENERATIF KELAPA DALAM DI DAERAH PASANG SURUT JAMBI / Path Coefficient Analysis of Vegetative and Generative Characters of Tall Coconut in Tidal Swamp Area of Jambi

Abstract

<p>Coconut improvement programs require knowledge of the effect of morphological characters on the coconut yield. The study aimed to determine the effects of fourteen morphological characters on the production of coconut meat character on Kampung Laut and Pengabuan tall coconut. This study was conducted in Kampung Laut and Pengabuan Villages, Jambi Province. Correlation analysis among 15 characters of vegetative, generative, and fruit components used the Walpole formula (1992). Fourteen characters affecting meat production were analyzed by using Path analysis of Singh and Chaudary formula following the R i386 3.5.2 software package in the Agricole package. Correlation analysis resulted in the characters of the number of leaves, number of bunches, number of fruits, polar circumference of fruit, weight of unhusked fruit, equatorial circumference of nut, and weight of endosperm correlated with the production of endosperm, on Kampung Laut tall coconut, while Pengabuan tall coconut have number of fruits, equatorial circumference of nut, and weight of endosperm. The results of path analysis showed that the characters of the number of bunches, number of fruits, and weight of endosperm had a significant direct effect on the production of endosperm on the Kampung Laut tall coconut. While on the Pengabuan tall coconut, only the fruits number and endosperm weight affected the endosperm production. The study indicates that the number of bunches, number of fruits, and weight of endosperm can be used as selection criteria to increase the production of the endosperm of the Kampung Laut and Pangabuan tall coconut.</p><p><strong>Keywords: </strong>Morphological characters, correlation, fruit components, selection</p><p> </p><p><strong>Abstrak</strong></p><p>Program perbaikan tanaman kelapa membutuhkan pengetahuan tentang pengaruh karakter morfologi terhadap hasil. Penelitian bertujuan untuk mengetahui pengaruh langsung dan tidak langsung 14 karakter morfologi terhadap produksi daging buah kelapa Dalam Pengabuan dan kelapa Dalam Kampung Laut asal Propinsi Jambi. Penelitian dilakukan di Desa Kampung Laut, Tanjung Jabung Timur dan Desa Pengabuan, Tanjung Jabung Barat, Propinsi Jambi pada tahun 2017. Analisis korelasi antar 15 karakter vegetatif, generatif, dan komponen buah menggunakan rumus Walpole (1992). Analisis sidik lintas 14 karakter vegetatif, generatif serta komponen buah terhadap karakter produksi daging buah per pohon per tahun, menggunakan rumus dari Singh dan Chaudary. Kedua analisis tersebut menggunakan program <em>software </em>R i386 3.5.2 <em>package Agricole</em>. Hasil Analisis korelasi menunjukkan karakter-karakter jumlah daun, jumlah tandan, jumlah buah, lingkar polar buah utuh, bobot buah tanpa sabut, lingkar equatorial biji, dan bobot daging buah berkorelasi dengan produksi daging buah, untuk kelapa Dalam Kampung Laut, sedangkan untuk kelapa Dalam Pengabuan adalah jumlah buah, lingkar equatorial biji, dan bobot daging buah. Hasil analisis lintas menunjukkan bahwa karakter jumlah tandan, jumlah buah, dan bobot daging buah berpengaruh langsung secara nyata terhadap karakter produksi daging buah untuk kelapa Dalam Kampung Laut, sedangkan untuk kelapa Dalam Pangabuan hanya dua karakter yang berpengaruh langsung terhadap produksi daging buah, yaitu karakter jumlah buah dan bobot daging buah. Hasil penelitian mengindikasika bahwa karakter jumlah tandan, jumlah buah, dan bobot daging buah dapat dijadikan sebagai kriteria seleksi untuk peningkatan produksi daging buah kelapa Dalam Kampung Laut dan kelapa Dalam Pengabuan.</p><p><strong>Kata kunc</strong>i: karakter morfologi, korelasi, komponen buah, produksi kelapa, seleksi.</p>

Zabak Tall as a potential coconut variety in tidal areas

“…However, this criterion must have a close relationship with the yield so that if it is used as a selection criterion, it is effective. Miftahorrachman et al, 2019 identified that the characters of the weight of endosperm, the number of fruits, and the number of coconut bunches in Kampung Laut (Zabak), which had a close and positive relationship with the yielding character, namely coconut meat production, while 13 characters others analyzed did not have a direct relationship with the character of coconut meat production [7].…”
