Genotype × environment interaction (G×E) of harvest period should be involved to assess the suitability of mungbean (Vigna radiata L. Wilczek) for monoculture or intercropping cultivations. This research was aimed to study the effect of G×E interactions on phenology and synchronous maturity, the change of genetic parameter estimates, and the stability of harvest period in mungbean. The study was conducted in Bogor, Indonesia, from December 2017 to October 2018 in four environments: wet season, monoculture (WS.M) and intercropping (WS.I); dry season, monoculture (DS.M) and intercropping (DS.I). Ten mungbean genotypes were evaluated in monoculture and intercropping with sorghum [Sorghum bicolor (L.) Moench] cultivar Numbu using a randomized complete block design with three replications. The phenological traits, namely days to flowering, days to the first harvest, days to 90% harvest, plant height, number of productive branches, seed weight per plant (SWP), and the synchronous maturity traits, namely harvest period, degree indetermination of plant height (DDh1), degree of indetermination of harvest period (DDd2), were observed. The results showed that the G×E interaction effect was highly significant (p < .01) for all phenological and synchronous maturity traits except DDd2. Phenotypic expression of all traits, except SWP and DDh1, were largely controlled by the genetic factor (h²_bs > 59.83%). Kefa, Kawur, VR480B, Lom2, MLB, Vima 2, VR10, VR60 were stable (b_i = 1), VR05 was sensitive (b_i = 1.70), and No.129 was insensitive (b_i = 0.66) and suitable for monoculture in the dry season. The GGE biplot showed Kefa as a stable genotype with the shortest harvest period. Mungbean selection for synchronous maturity can use harvest period trait in monoculture at dry season.

环境相互作用对绿豆物候和同步成熟的基因型

应考虑收获期的基因型×环境相互作用（G×E）来评估绿豆（Vigna radiata L. Wilczek）对单一栽培或间作栽培的适宜性。本研究旨在研究G×E互作对绿豆物候和同步成熟、遗传参数估计值的变化以及收获期稳定性的影响。该研究于 2017 年 12 月至 2018 年 10 月在印度尼西亚茂物进行，在四种环境中进行：雨季、单一栽培 (WS.M) 和间作 (WS.I)；旱季、单一栽培 (DS.M) 和间作 (DS.I)。在单作和高粱间作中评估了 10 种绿豆基因型 [ Sorghum bicolor(L.) Moench] 栽培品种 Numbu，采用随机完整区组设计，重复三次。物候性状，即开花天数、第一次收获天数、收获 90% 天数、株高、生产枝数、单株种子重量 (SWP) 和同步成熟性状，即收获期、程度不确定观察到植物高度 (DDh1)、收获期的不确定程度 (DDd2)。结果表明， 除 DDd2 外，所有物候和同步成熟性状的 G×E互作效应都非常显着 ( p < .01)。除 SWP 和 DDh1 外，所有性状的表型表达在很大程度上受遗传因素控制（h ² _bs  > 59.83%）。Kefa、Kawur、VR480B、Lom2、MLB、Vima 2、VR10、VR60 稳定（b_i  = 1），VR05敏感（_bi  = 1.70），No.129不敏感（_bi  = 0.66），适合旱季单作。GGE 双标图显示 Kefa 是收获期最短的稳定基因型。同步成熟的绿豆选择可以利用旱季单一栽培的收获期性状。
