水稻主要经济性状的遗传力估测,国内外已有了不少的报导,但遗传力的估计,因所用的材料和方法不同,因各地的具体环境不同,而有差异。本项试验的目的,在本省本区的条件下,从我院水稻育种材料中选用几个杂交组合,按照梅赛尔(K.Mather,1949)所提出的完全随机排列法布置试验,从亲、子代的各类方差估算遗传力。我们认为这类设计疗法机动灵活,较少受供试材料数量的限制, Estimates of the heritability of major economic traits in rice have been reported at home and abroad. However, estimates of heritability vary depending on the materials and methods used. The purpose of this experiment was to select a few hybrid combinations from rice breeding material in our hospital under the conditions of our province and set the test according to the completely random arrangement proposed by K. Mather (1949) , All kinds of offspring to estimate heritability. We think this kind of design therapy is flexible and less limited by the quantity of materials tested,
