花生在世界上种植较广,但产量较低,单产多低于800～2000kg/ha荚果。而高产地块可达4000～7000kg/ha荚果,表明花生的高产潜力尚未开发出来。自Donaid提出了有关作物的“理想株型”以来,已出现了几种定义和理论,但论及花生的极少。本文探讨了花生“理想株型”应具有的特征,从品种的亚种划分和干物质分配入手,研究了来源于亚种间杂交的几个日本品种的具体表现。
Peanuts are widely planted in the world, but with lower yields and yields below 800-2000kg / ha pods. The high-yield plots up to 4000 ~ 7000kg / ha pods, indicating that the peanut yield potential has not yet been developed. Since Donaid proposed “ideal plant types” for crops, several definitions and theories have emerged, but few have been given to peanuts. In this paper, the characteristics of “ideal plant type” in peanut should be discussed. Starting with the subspecies classification and dry matter allocation, the specific performance of several Japanese cultivars derived from the subspecific hybridization was studied.
