摘要
中籼3037由江苏农学院育种教研组育成,具有较好的丰产性、稳产性和抗逆性,米质优:每亩总颖花量在3000万以内时产量随总颖花量的提高呈线性增加(r=0.8273);就扩库而言,增穗比增粒的作用大。每亩穗数在15.9～25.13万范围内,穗数与产量呈极显著线性正相关(r=0.8442)。最适叶面积指数为6.98。培育壮秧,促进早发,争取在适宜穗数的基础上扩大库容量是中籼3037获得高产的重要栽培途径。
The cultivar 3037 was bred by the Crop Breeding Department of Jiangsu Agricultural College.Results of the study indicated that: (1) 3037 had better productivity, better stability of yield, stronger resistance to diseases and better grain quality; (2) It had a big number of spikelets per mu (about 30 million) and there was a linear correlation between yield and total number of spikelets per mu (r=0.8273).As regards to enlarge sink, the effect of increasing panicles per mu was larger than that of increasing grains per panicle. (3) There was a linear correlation between yield and panicles (r=0.8442) when panicle numberat the range of 159-251 thousands per mu. (4) It had a optimum LAI about 6.98.It was important for high-yielding cultivation of 3037 to breed sturdy seedlings and to inrease tillers at early stage to enlarge the sink capacity
