秦油二号(原名杂37)系陕西省农垦科教中心用甘蓝型油菜雄性不育系6223A与恢复系C_1配制而成的杂交种。1986年经农业部鉴定,1987年列入“丰收计划”并在全国推广,现已在陕西关中、黄淮和长江南北各省广大地区试种,增产十分显著。1987年秋我所从陕西引进少量种子,在红壤丘陵地区的水田和旱地共试种4.6亩。其中旱坡地直播1.5亩,亩产182.9公斤,比相同地段直播的当地主栽品种饶油一号亩产95.45公斤,增产87.45公斤,增产率91.6％;水田移栽3.12亩,共收油菜籽725.86公斤,亩产达241.3公斤,创我场历年来的油菜单产最高纪录。
Qinyu No.2 (formerly known as Za 37) is a hybrid of Shaanxi Province Land Reclamation Science and Education Center with the male sterile line 6223A of rapeseed (Brassica napus L.) and restorer line C_1. It was appraised by the Ministry of Agriculture in 1986 and included in the “Harvest Plan” in 1987 and was popularized in the whole country. It has been tested and raised significantly in a large area of Guanzhong, Huanghuai and northern and southern provinces of Shaanxi Province. In the autumn of 1987, we introduced a small amount of seeds from Shaanxi and planted 4.6 mu of paddy field and dry land in the red soil hilly region. Among them, 1.5 mu of dry land was planted and 182.9 kg of mu per mu were produced. Compared with the same lot, the local cultivars Raoyou No.1 produced 95.45 kilograms per mu, an increase of 87.45 kilograms, an increase rate of 91.6%; 3.12 mu of paddy field transplanting and a total of 725.86 rapeseed Kg, yielding 241.3 kilograms per mu, creating the highest record of rapeseed production in our field over the years.
