Genetic Parameters, Correlation and Path Analysis for Seed Yield and Morphological Characters in Niger [Guizotia abyssinica (l.f.) Cass.]

The use of quality and certified seeds is an absolute requirement in the construction of the seed garden of coconut plant. Lobu tall coconut is one of the potential coconuts owned by North Sulawesi Province. The research was conducted in Lobu Village, Touluwaan District, Southeast Minahasa Regency, North Sulawesi Province from 2016 to 2018. The purpose of the study was to determine the characters that directly have an impact on the yield using path analysis based on Singh and Chaudary Formula on twelve morphology characters using programme of R i386 3.5.2 package Agricole software. The results of a simple correlation analysis show that there is no relationship between morphological characters and number of fruits, but correlates with the weight of whole fruit. The results of the path analysis showed that only the seed weight character had a direct effect on the weight of whole fruit (r = 0.53) and there were no indirect effects. Seed weight characters can be used as a selection criteria of mother palms to increase coconut productivity of Odeska Lobu coconut.ABSTRAKPenggunaan benih berkualitas dan bersertifikat merupakan syarat mutlak dalam pembangunan kebun induk tanaman kelapa. Kelapa Dalam Odeska Lobu merupakan salah satu kelapa potensial yang dimiliki daerah Provinsi Sulawesi Utara. Kegiatan dilakukan di Desa Lobu, Kecamatan Touluwaan, Kabupaten Minahasa Tenggara, Provinsi Sulawesi Utara, mulai tahun 2016 sampai dengan tahun 2018, untuk mengetahui karakter-karakter yang berpengaruh langsung terhadap hasil, dilakukan dengan menggunakan analisis sidik lintas berdasarkan formula Singh dan Chaudary terhadap dua belas karakter vegetatif, generatif, dan komponen buah menggunakan program software R i386 3.5.2 package Agricole. Hasil analisis korelasi sederhana menunjukkan tidak terdapat hubungan antara karakter morfologi dengan karakter hasil jumlah buah, tapi berkorelasi dengan karakter hasil berat buah utuh. Hasil analisis lintas menunjukkan hanya karakter berat biji yang berpengaruh langsung terhadap berat buah utuh (r = 0.53) dan tidak terdapat pengaruh tidak langsung. Karakter berat biji dapat dimanfaatkan sebagai kriteria seleksi pohon tetua sebagai sumber benih untuk meningkatkan produktivitas kelapa Dalam Odeska Lobu.

AbstractThis study was carried out to determine the correlation between agronomic traits and seed yield of sunflower hybrids and also to determine the direct and indirect effects of analyzed traits on seed yield. The primary task in sunflower breeding programs is to increase the seed yield, as well as create new hybrids with high potential for seed and oil yield. The experiment was set up according to randomized block design during two growing seasons (2013 and 2014), on research area of the Faculty of Agriculture, “Goce Delchev” University – Shtip, in Ovche Pole locality, Republic of Macedonia. As an experimental material 20 sunflower hybrids were used. 1,000 seed weight, seed length and width, oil content, oleic acid content and seed yield were analyzed. 1,000 seed weight showed positive and significant correlation with seed width, seed length and seed yield. On the other hand, negative and significant correlation was obtained between 1,000 seed weight and oil content. 1,000 seed weight expressed the highest positive direct effect on seed yield. The results obtained from correlation and path analysis showed that the efficiency in the selection of seed yield in sunflower hybrids should increased through the selection of 1,000 seed weight.
