Abstract

Penelitian ini bertujuan mengevaluasi keragaman karakter morfologi dan agronomi 13 populasi F 1 half-sibubi kayu di Bandar Lampung. Evaluasi dilaksanakan pada bulan Maret 2016 – Februari 2017. Populasihalf-sibmerupakan keturunan tetua betina Adira, CMM, CMM 25-27-43, CMM 25-27-46, CMM 25-27-143, CMM 25-27-158, CMM 97-6, Malang, Macan, T142, T12, T15 dan UJ5. Karakter morfologi dan agronomi meliputikarakter kualitatif dan kuantitatif. Keragaman karakter kualitatif luas jika persentase fenotipe rekombinan (PFR) > 67%, sedang jika 33%<PFR < 67% dan sempit jika PFR < 33%. Keragaman karakter kuantitatif dinyatakan luas jika kisaran total (range)> 2x Interquartile Range (IQR)dan sempit jika Range<2 x IQR. Karakter kualitatif tanaman ubi kayu meliputi warna daun pucuk, warna permukaan atas tangkai daun, dan warna permukaan bawah tangkai daun pada 13 populasi tersebut menunjukkan keragaman yang luas atau sedang kecuali warna permukaan atas tangkai daun pada populasi CMM 25-27-46 yang berkeragaman sempit. Karakter kuantitatif meliputi panjang lobus, lebar lobus, rasio panjang/lebar lobus, panjang tangkai daun dan rendemen pati menunjukkan keragaman yang luas pada populasihalf-sibCMM 25-27-43, CMM, Malang, T12, dan Macan. Populasihalf- sibAdira, CMM25-27-46, CMM 25-27-143, CMM 25-27-158, CMM 976, T15, T142 dan UJ5 menghasilkan keturunan dengan keragaman yang sempit dan luas.

Abstract

The purpose of this study was to evaluate the agronomic characters and yield potential of ten new plant type (NTP) of rice genotypes planted on two different agroecologies. The study was done in East Lampung (Ultisols soil type, altitude 60 m asl, and average daily temperature 26,86°C) and Tanggamus (Andisols soil type, altitude 600 m asl, and average daily temperature 24.15°C) in January—Juni.  The research was arranged in randomized complete block design (RCBD) with 12 treatments and 3 replications. The treatment consisted of 10 new type of rice genotypes, i.e., IPB 3S, IPB 4S, IPB 5R, IPB6R, IPB117-F-7-2-1, IPB 117-F-7-7- 1, IPB 117-F-14-4-1, IPB 117-F-15-4-1, IPB 117-F-20-1-1, IPB 117-F-80- 2-1, and two varieties, i.e., Ciliwung and Ciherang as control. The results showed that all NPT genotypes had lower number of tillers but the hill height were taller than the Ciliwung and Ciherang varieties. Eight genotypes had a faster harvesting time, and one genotype had a higher yield than two control varieties.
