本文用113个中熟组合的2140个F_6代系选株行的田间目测鉴评资料,从目测等级不同株系的实测产量、农艺性状差异及目测等级与性状相关性、目测等级与入选率关系的4个方面讨论了目测选择作为田间初选株系的效果和可行性,并以此讨论了田间目测鉴评选择在大豆杂交后代的高产育种中的应用。
In this paper, 113 mid-field combinations of 2140 F6 lines were selected for field visual evaluation. The correlations between visual grade and traits, visual grade and enrolling rate , Discussed the effect and feasibility of visual selection as the primary line in field and discussed the application of field visual evaluation in high yielding breeding of soybean cross.
