在常规中籼稻育种中,无论是形态株型育种,还是高光效生理育种,其实质都是协调每亩穗数、每穗实粒数和千粒重三者之间的关系,从中找出最佳值.本文应用数理统计方法,对常规中籼稻产量与产量构成因素间的关系进行分析研究,以探讨我省常规中籼稻高产品种的合理结构,明确育种方向.采用江苏省1981~1983年中籼稻新品种区域试验、新品系联合鉴定试验以及江苏里下河地区农科所1983年中籼稻新品系鉴定共80个品种(系)资料
In conventional indica rice breeding, no matter it is morphological type breeding or high light efficiency physiological breeding, its essence is to coordinate the relationship between the number of spikes per panicle, the number of spikelets per panicle and the weight of 1000-grain weight, and find the optimal value In this paper, the relationship between the yield and yield components of conventional mid - season indica rice was studied by means of mathematical statistics to explore the reasonable structure of high - yielding indica rice varieties in our province and clarify the direction of breeding.Using the indica rice from 1981 to 1983 A total of 80 varieties (lines) of regional trials of varieties, the joint identification test of new lines and the identification of middle-late indica rice lines in 1983 in Lixiahe, Jiangsu Province
