大豆新品种豫豆二号是用“郑7104×滑县大绿豆”进行有性杂交、系谱法选育而成,具有丰产、稳产、优质、适应性广、抗病性强、耐肥、抗倒和对光温反应迟钝的特点.在河南省以及相邻地区种植,生育期100—105天,麦田套种和夏播皆可.本文利用一年多点和多年多点试验资料,通过方差分析、模糊数学评判等综合评价了豫豆二号的丰产性、稳产性和抗病、抗倒性能,进一步探讨了豫豆二号高产的生物学特性和丰产栽培技术要点.
The new soybean variety Yudou No.2 was made by sex hybridization and pedigree method with “Zheng 7104 × Huaxian large mung bean”. It has the characteristics of high yield, stable yield, high quality, wide adaptability, strong disease resistance, Down and slow response to light and temperature characteristics in Henan Province and adjacent areas planted, the growth period of 100-105 days, wheat field intercropping and summer broadcasting can be more than one year and many years of multi-point test data, analysis of variance , Fuzzy mathematics evaluation and other comprehensive evaluation of Yudou No.2 on the high yield, stable yield and disease resistance, lodging resistance, to further explore the Yudou No.2 high yield biological characteristics and high yield cultivation techniques.
