摘要

本研究以大豆高雄選10號為試驗材料，探討栽種於臺中市區域之大甲（Dajia）、大安（Daan）、清水（Cingshuei）、梧棲（Wuci）、龍井（Longjing）與大肚（Dadu）等六地區之產量試驗及相關性分析。試驗結果顯示，高雄選10號在六地區之生育期約在102～112天之間，而其農藝性狀也有顯著性差異，其中試作區每公頃帄均產量分布於1,974～3,977公斤。在進行大豆產量與其構成要素之農藝性狀相關性分析時顯示，產量與植株高度、始莢高度、單株節數有呈顯著正相關，與單株分枝、單株莢數、單株粒重及百粒重未呈顯著相關。此外，植株高度與始莢高度亦呈顯著正相關。進一步以單位面積估計之產量及其構成要素進行分析，可發現在相同播種量下產量與株數、莢數、粒數等單位面積構成要素為正相關。

The purpose of this experiment is to evaluate growth characters and their correlation with yield of soybean variety 'KSS10' in the ratoon rice field of Taichung in 2014. Experiment plots included Dajia, Daan, Cingshuei, Wuci, Longjing and Dadu. The results showed that the growth period of 'KSS10' was about 102 to 112 days. The agronomic characters of yield components of 'KSS10' were significant different and the average yield were 1,974-3,977 kg/ha in experiment plots. Further, on the correlation analysis of yield and plant agronomic traits showed that yield was significantly correlated with node number on main stem (NN) but not significant with branch numbers (BN), pod number per plant (PNP), seed weight per plant (SW) and 100-grain weight (HGW). Correlation analysis of yield per unit area and agronomic traits showed that total numbers of plants per unit area, pod numbers per plot and grain numbers per plot were significantly correlated. In addition, plant height (PH) and lowest pod site (LPS) were significantly positively correlated.
