In this research, the ~ and F2 of the crosses between a natural mutant 慪34?with super-minute grain and 慪38?with super-large grain,慡huhui 881擲huhui 527?with middle grain size were carried out to study the inheritance of the grain shape (grain length, grain width, grain thickness and grain length/width ratio) and 1000-grain weight. The main results are summarized as below:? The F1 grain length, grain width, grain thickness and 1000-grain weight of three crosses were lay between the two parents and tended to Y34, which indicated that those grain traits were all governed by the dominant effect of Y34 and influenced by both female and male parents. The differences of F1 grain length, grain width, grain thickness and 1000-grain weight of positive and negative crosses between Y38 and Y34 indicated the existence of cytogene effects.? The broad heritabilities of major grain traits were calculated.

本研究利用一份水稻极小粒自然突变材料Y34与一份水稻极大粒材料Y38、两份常规籽粒大小材料蜀恢881、蜀恢527的杂交F_1及F_2，对主要粒形性状（粒长、粒宽、粒厚、长宽比）及千粒重进行了遗传研究，根据遗传研究的结果利用微卫星标记结合F_2群分法对控制Y34短粒性状基因进行了分子标记定位，主要结果如下：●各组合F_1粒长、粒宽、粒厚和千粒重介于双亲之间且明显偏向于小值亲本 Y34，这表明粒长、粒宽、粒厚和千粒重均主要受小值亲本显性基因的控制并同时也受大值亲本核基因的影响。Y34与Y38正反交F_1在粒长、粒宽、粒厚、千粒重等性状上存在差异，表明存在细胞质效应。

The results were as follows, the total cultivated area of Liaoning province has declining tendency in recent 26 years, the total grain yield and the grain yield per unit area increased in "wave" style; the grain yield per unit area and total planting area had the great effect on total grain yield, and the effect of yield per unit area on total grain yield is bigger than that of planting areas; the yield and the planting area of different crops also affected total grain yield greatly, and maize, rice, durra, wheat affect the total grain yield by grain yield per unit area, while millet, maize, wheat affect the total grain yield through planting area changing.

得出如下结论，辽宁省近26年粮食总播种面积呈下降趋势，粮食总产量和平均单产受气候条件影响呈波动式增加；粮食总播种面积和平均单产均显著影响着粮食总产量的变化，并且粮食平均单产的变化对总产的影响要大于粮食播种面积的影响；各种作物的产量和播种面积变化都影响粮食总产量的变化，但各种作物对粮食总产量影响的方式不同，其中玉米、水稻、高粱和小麦主要是通过单产的变化影响粮食总产量，谷子、玉米和小麦则是通过播种面积的改变来影响粮食总产量的变化。

Result Richards Model and Monodic Quadratic Equation could properly describe grain dry matter growing process and the change process of grain filling rate with days after anthesis. There was big difference in average grain filling rate, maximum grain filling rate under different planting density. Average grain filling rate 1.26 mg/ and maximum grain filling rate 2.44 mg/ of T7 were the quickest, and the average grain filling rate 0.94 mg/ and maximum grain filling rate 1.99 mg/ of T12 were the slowest, and the maximum difference percentage of the average grain filling rate and maximum grain filling rate among different density were 33.98%, 22.61%. There was significant correlation between average grain filling rate, maximum grain filling rate, grain filling active duration, rapid increasing stage and thousand grain weight, and the correlation coefficients were 0.628*, 0.630*, 0.849**, 0.739**. Active grain filling duration contributed mostly to TGW.

结果不同密度处理间千粒重、单位面积穗数、穗粒数、单株穗数、单位面积籽粒产量均存在显著差异；不同密度处理冬小麦的籽粒灌浆均符合慢－快－慢的&S&型生长特性，用Richards模型能很好地模拟冬小麦籽粒增重过程，用一元二次抛物线方程能较好地模拟冬小麦灌浆速率随花后时间变化过程；不同密度处理间平均灌浆速率、最大灌浆速率有较大差异，最大差异率分别为33.98%、22.61%，T7的平均灌浆速率1.26mg/及最大灌浆速率2.44mg/均最大，T12的平均灌浆速率0.94mg/及最大灌浆速率1.99mg/均最小；平均灌浆速率、最大灌浆速率、灌浆活跃期、灌浆快增期与千粒重显著或极显著正相关，相关系数分别为0.628*、0.630*、0.849**、0.739**；通径分析表明，灌浆活跃期对千粒重的贡献最大。
