Genotype-Environment Interaction and Yield Stability of Upland Rice in Intercropping Cultivation

Rice cultivation as intercropping in plantations is a potential approach to increase land resource efficiency. Implementation of rice would require genotypes adapted shaded environments. This study aimed clarify the interaction genotype and environment on agronomic characteristics upland grown under system identify suitable for this particular cropping system. Multi-location trials evaluated twelve lines two check varieties eight sites during wet season (WS) 2015-2016. was six monoculture sites. intercrop cultivated between tall coconut, rambutan, teak, albizia, natural rubber. The result revealed that significant all characteristics. B12056F-TB-1-29-1 best performer when Subang Indramayu, with shading intensities 65% 44%, respectively. B11908F-TB-3-WN-1 yielder Cianjur Lampung Tengah, which had 37% 54% intensity, B12825E-TB-2-4 Timur intensity 45%, while Jatiluhur Banyumas 82%. yield monocultures higher than intercropping. Among genotypes, showed highest across Stable high-yield identified from are expected be adopted by farmers cultivation.
