８ａ引种试验结果表明，大豆７９６４５选系在西宁生态条件下生育期平均１１６ｄ。出苗６０ｄ左右茎叶生长速度最快，７０ｄ前后开始结荚，８０ｄ左右植株鲜重和干重增长速度最快，９０ｄ左右营养生长量、单株荚果数和物质生产积累量均达一生最高值，１００ｄ左右荚果大小基本定型。此后生长急剧减缓渐趋成熟。最高产量达２８９５．１ｋｇ／ｈｍ２。
The results of the introduction experiment of 8a showed that the 79645 soybean selection line had an average growth period of 116 days under the ecological conditions in Xining. After 60 days of emergence, the growth of stems and leaves was the fastest, and the pods began to grow around 70 days. The fresh weight and dry weight of the plants around the 80th day were the fastest, and the vegetative growth, pod number and material production accumulation reached the highest values in their lifetime. About 100d pod size basic shape. Rapid growth since then slowed down gradually matured. The highest output reached 2895.1kg / hm2.
