Abstract

The productivity of existing rice varieties has plateaued, while the area of rice fields continues to decline and the population continues to grow. Efforts to develop higher-yielding rice varieties have been made, one of which is the development of the multi-canopy rice system. This study aimed to assess the agronomic performance of tall and short rice genotypes in a multi-canopy (MC) system across two planting seasons. This study evaluated 22 MC combinations and two monoculture checks (‘Inpari 32’ and ‘Ciherang’) using a randomized complete block design with 3 replications, across dry and wet seasons at IPB University’s Babakan station. The results of the study showed that a significant C×S interaction was found only for the number of filled grains (NFG) trait. A better performance is generally observed in the dry season. The best performing combination was D15 (IPB200-F-60 and IPB200-F-12), which produced the highest grain yield of 7.27 tons/ha, outperforming the check varieties. Total number of tillers (TNT), number of productive tillers (NPT), and number of filled grains (NFG) were positively and significantly correlated with yield. MGIDI analysis identified multi-canopy combinations D15, D6, D20, D19, D1, D12, and D9 as potential based on six traits. These combinations should be tested across a wider range of environments to further elucidate the effect of genotype-by-environment interaction.
