杂交小麦MS1丰产稳产性研究

Studies on High Yield and Stability of the Hybrid Wheat MS1

杂交小麦MS1是高产稳产性好的优良杂交小麦品种 ,MS1的有效穗在每公顷 2 82 .6～ 5 0 4 .0万穗之间 ,千粒重在 35 .3～ 5 2 .4 g之间 ,二者变异系数较小 ,稳定性好 ,穗粒数在 2 9.0～ 4 5 .3粒之间 ,稳定性一般 ,随环境变化大。三要素的HSC系数均居于中间位置 。

The hybrid wheat MS1 was characterized by with high yield and good stability.The effective spikes were between 282.2×10 4～504.0×10 4 spikes/hm 2.The 1000-grain weihgt was between 35.3～52.4 g.C.V.of both the effective spikes and the 1000-grain weihgt was low.The kernel per spike was between 29.0～45.3 grains.The stability of the hybrid wheat MS1 was average and the enviorenment had great effect on it.HSC of three factors was medium.This indicated the hybrid wheat MS1 had the good adaptability.
