The heritability and repeatability of various characters affecting thebaine and seed yields in Papaver bracteatum were estimated from parents and progeny families during two consecutive years of growth. Thebaine and seed yields per plant showed the lowest heritability and therefore low selection response. High selection responses were obtained for thebaine content of the capsules and mean weight per capsule, and are therefore the most appropriate criteria for increasing the thebaine yield per plant or per unit area. Similarly seed yield per capsule is more advantageous as a selection criterion for increasing the yield of seeds.
利用两年的生长时间，从亲本和后代群体中估算了影响罂粟裂片和种子产量的各种性状的遗传力和可重复性。单株罂粟碱和种子产量的遗传力最低，因此选择反应也最低。而每胶囊罂粟碱含量和每胶囊平均重量的选择反应较高，因此是提高单株或单位面积罂粟碱产量最适合的标准。同样，每胶囊种子产量作为提高种子产量的选择标准也更有利。
