经过多年的育种研究实践，提出水稻超高产育种要取得成功，必须培育高光合速率的品种。反映在田间选择方法上，从苗期至成熟期以分蘖发生早、分蘖力和分蘖势强、叶色浓、叶片厚、叶片小穗子大、单株穗整齐度好、根系寿命长、植株不早衰、紧凑型或小杯型为形态指标，单株穗数和单穗重量为选择依据进行选择，用这种方法育成的超高产稻种“三优”在贵州表现良好，产量高达８００ｋｇ／６６６，７ｍ２以上。
After many years of breeding research and practice, it is proposed that the super-high-yielding rice should succeed in cultivating the varieties with high photosynthetic rate. It is reflected in field selection methods that early tillering, tillering ability and tillering potential are strong, leaf color is thick, leaves are thick, leaf spikelets are large, ear uniformity is good, root life is long, and plant is not Premature aging, compact or small cup shape for the morphological indicators, the number of panicles per panicle and the weight of a single ear to choose based on the selection of super-high yielding rice breed by this method, “Miyoshi” performed well in Guizhou, the yield of up to 800kg / 666 , 7m2 above.
