The difference of effect occurred by IPT gene to yield and yield components were observed in different background of rice and environment.
IPT基因对产量和产量构成因素的影响因遗传背景、地点、年份不同而表现出差异。
Of the yield components, filled grains numbers per panicle showed the most variant extent of effect by IPT gene, followed by panicles per plant, seed set ratio and 1000-grain weight.
IPT基因对产量构成因素的效应变异幅度最大的是穗实粒数，然后依次是单株穗数、结实率和千粒重。
