Agronomic Appearance, Genetic Parameters of Red and Black Rice (Oryza sativa L.) in Different Environments Dry Land

Increasing yield and adaptability of brown black rice in functional sub-optimal environments begins with increasing genetic diversity through conventional crosses between diverse germplasm. This study aims to determine the yield, diversity, heritability, interactions genotypes two different growing environments. The was conducted April-August 2021. designed using a two-factor Randomized Block Design (RAK) three replications. first factor genotype consisted 15 treatments, namely: 6 lines (G1-G6), five (G7-G11), parents are Baas Selem (G13), Situpatenggang (G14), GH Padi red (the elder line) one comparison variety Inpago Unram 1 (G15). second consists locations: Tampak Siring Village, Batukliang District (379 m asl) Mujur Praya Timur (103 Central Lombok Regency. results showed that (G15) higher than other genotypes, namely 7.10 t/ha. exact as (brown strain parent) Situ Patenggang (black were G6 G10 value 5.21 t/ha 5.35 t/ha, respectively. High heritability values indicated by plant height grain while traits classified low moderate range below 0.20 0.45. coefficient number productive tillers relatively high, 51.27%. Slightly obtained for non-productive 38.63% 48.26%, Developing recommended because they have yields. All tested able adapt
