在早熟玉米(Zea mays L.)种质中,收获期籽粒产量与籽粒含水量是呈正相关的性状(Mather 等,1989)。籽粒产量与籽粒含水量的比值已被 Guelph 大学及一些地区的玉米育种者作为一个选择标准,对晚熟群体应用这一标准选择有益于增加产量,降低籽粒含水量;对适宜熟期的群体有益于增加产量,并不
In early maturity maize (Zea mays L.) germplasm, grain yield at harvest was positively correlated with grain moisture content (Mather et al., 1989). The ratio of grain yield to grain water content has been used as a selection criterion by Guelph University and some corn breeders in some areas. Applying this standard selection to late-maturing populations is beneficial for increasing yield and reducing grain moisture; it is of benefit to populations suitable for maturity Increase output, no
