绵农２号是由四川省绵阳农业专科学校选育、１９９２年通过四川省作物品种审定委员会审定的小麦新品种，它具有穗大、粒多（６５～８０粒／穗）、小穗数多（结实小穗数达２０～２５个／穗）、产量高（比绵阳１１号增产１０％～２６％）等特点。该品种的选育方法也具有独创性，归纳起来有以下几点：（１）多组合小群体确定目标组合；（２）在目标组合中确定重点目标组合；（３）在重点目标组合中确定重点株系；（４）进行阶梯式杂交。 Mianong 2 was bred by Mianyang Agricultural College in Sichuan Province. It passed the approval of Sichuan Crop Variety Approval Committee in 1992 and has the characteristics of big spike, large grain (65 ~ 80 grains / spike), more spikelets (Strong spikelet number of 20 ~ 25 / spike), high yield (than Mianyang 11 yield 10% ~ 26%) and other characteristics. Breeding methods of this variety are also original. The following points are summed up: (1) multiple combinations of small groups to determine the target portfolio; (2) to determine the key target portfolio in the target portfolio; (3) to determine in the key target portfolio Key lines; (4) for step hybridization.
