稻种可变与系统选育我省贫下中农,在选育新品种过程中,揭露了稻种可变的规律,丰富了选种学说的内容,有着深刻的辩证唯物主义观点和科学道理。稻种可变从水稻育种实践中,可以看到水稻品种性状变异的表现。例如,从高秆品种“中山红”育成矮秆品种“钢枝占”,从中秆品种“溪南矮”育成矮秆品种“矮溪南”;从“广二矮”中育成分蘖性强的“广二矮选2号”,从“广塘矮”中育成分蘖性强的“平广矮”;从“珍珠矮”中育成大穗多粒的“珍珠矮选2号”和“大粒珍珠矮”;从“包胎矮”中育成“包胎
Rice Variety and System Breeding In the province of poor and middle peasants, in the process of breeding new varieties, we exposed the variable rules of rice varieties, enriched the content selection theory, and have profound dialectical materialist views and scientific truths. Variety of rice varieties from rice breeding practice, you can see the performance of rice varieties traits variation. For example, the dwarf variety “Dianzhangzhan” was bred from the “Zhongshan Red” stalk variety and the dwarf variety “Dwarf Xinnan” was bred from the middle stalk variety “Xinnan Dwarf”. From “Guang Er Dian” “Guang Er short selection 2”, from the “Guangtang dwarf” in the strong component of the bushy “flat wide short”; from the “pearl dwarf” bred large ears and more grain “pearl dwarf 2” and “big pearls Dwarf ”; bred“ from the ”low birth weight" package
