Abstract

Induksi mutasi fisik dengan iradiasi sinar gama merupakan salah satu pendekatan untuk meningkatkan keragaman genetik sehingga mendukung proses seleksi dalam program pemuliaan tanaman. Penelitian ini bertujuan mendapatkan informasi keragaman karakter agronomi dan seleksi populasi kacang hijau M2 VR10. Pengujian populasi M2 VR10 hasil iradiasi sinar gama 880 Gy dilaksanakan di Kebun Percobaan Leuwikopo IPB pada Februari hingga Juni 2018. Sebanyak 480 tanaman M2 dan 120 tanaman M0 (VR10) sebagai kontrol ditanam bersamaan. Populasi M2 VR10 menunjukkan keragaman karakter warna hipokotil, pertumbuhan daun pertama, keberadaan warna antosianin serta trikoma pada batang dan tangkai daun, bentuk biji, warna biji, dan kekilapan biji. Keragaman genetik berdasarkan nilai heritabilitas tergolong tinggi (50.7-93.0%), teridentifikasi pada karakter tinggi tanaman (saat berbunga, panen pertama, panen terakhir), umur berbunga, umur panen (panen pertama, panen terakhir), periode panen, bobot polong total, jumlah biji per polong, jumlah polong total, dan panjang polong. Seleksi karakter periode panen berdasarkan frekuensi seleksi 10% menghasilkan 46 genotipe M2-VR10 dengan periode panen 13-31 hari dan memberikan diferensial seleksi -2.99. Kata kunci: frekuensi seleksi, heritabilitas, M0, periode panen, seleksi diferensial

Abstract

Genetic variability is critical in order to create candidates for new superior varieties. This research objective was to evaluate the performance and variability of agronomical traits on the mungbean SSD F4 V422H/129 population. The research was conducted at IPB University, Bogor, from March to June 2021. The SSD F4 VR422H/129 population (378 genotypes with single plant as a representative of one genotype) and five check varieties were evaluated. The treatments were arranged in augmented design for RCBD in three replications. For agronomical traits, every F4 plant and 10 sample plants for each check variety were observed. Statistical analysis includes mean, frequency-distribution, heritability, genetic variability, correlation. The days to flowering, days to harvesting, generative periods, plant height on F4 V422H/129 were not significantly different from Vima 5, while total pod number, total pod weight, total seed weight, pod length were significantly higher. The agronomical traits were affected by genetic factors (heritability 0.71-0.99%), except for days to harvest. Based on the high genetic variability (CGV 0.62-0.64%), it was possible to select of total pod weight, total seed weight, or pod length in the next generation V422H/129. The total seed weight had a significant positive correlation with total pod weight and pod length.
