摘要

本研究旨在了解G × E互作对低地水稻双单倍体株系(DH)产量的影响，以期获得稳产高产株系。实验在Indramayu(2018)、Subang(2018)、Malang I(2018)、Malang II(2019)、Blitar(2019)、cianjurr(2019)、龙目岛(2019)、巴厘岛(2019)和Madiun(2019) 9个环境(E)中进行。采用随机完全区组设计，每组3个重复。鉴定的基因型为14个双单倍体水稻品系和2个对照品种慈和让和18号。综合方差分析结果表明，基因型(G)、环境(E)和基因型与环境(G × E)互作对籽粒产量有显著影响。G1、G4、G9、G10、G11、G12、G13和G14 DH系的基因型平均产量高于平均值。在这些基因型中，G9的DH系根据Francis和Kannenberg、Finlay-Wilkinson、Eberhart-Russell、Kang、

GENOTYPE × ENVIRONMENT INTERACTION AND STABILITY ANALYSIS FOR HIGH YIELDING DOUBLED HAPLOID LINES OF LOWLAND RICE

This study was aimed at obtaining information on the effects of G × E interaction on yield among doubled haploid lines (DH) of lowland rice and to obtain stable and high yielding lines. The experiment was conducted in 9 environments (E), namely Indramayu (2018), Subang (2018), Malang I (2018), Malang II (2019), Blitar (2019), Cianjur (2019), Lombok (2019), Bali (2019), and Madiun (2019). A randomized complete block design with 3 replications was used in each location. The genotypes evaluated were fourteen doubled haploid rice lines and two check varieties namely Ciherang and Inpari 18. The results of the combined analysis of variance indicated significant effects of genotype (G), environment (E), and genotype × environment (G × E) interactions on grain yield. G1, G4, G9, G10, G11, G12, G13, and G14 DH lines had higher genotype mean yield than the average. Among those genotypes, the DH line of G9 was classified as high yielding, stable, and widely adapted in all locations based on Francis and Kannenberg, Finlay-Wilkinson, Eberhart-Russell, Kang,
