应用HSC法评价蚕豆高产稳产性

用高稳系数（HSC）法分析了1999年吞豆区域试验7个参试品种的高产稳产性，结果表明，95－08高产又稳产，95－20产量一般，但稳产性好，95－25丰产性最好，但稳产性很差，95－22稳产性最好，但丰产性最差，95－23既低产又不稳产，HSC是反映高产性的参数，又是反映稳产性的参数，使高产与穗产两因素得到了科学的有机结合，用HSC法分析评价蚕豆新品种高产稳产性是一种准确，简便，可靠的方法。

Appraising High and Stable Yield of Broad Bean with High Steady Coefficient Method

The high and stable yield of seven broad bean varieties were analysed with( HSC ) in 1999. The result showed that 95-08 variety has high and stable yield. The output of 95-20 variety is general but it is more stable. 95-25 variety has the highest yield,but its stability is poor.95-22 variety is most stable, but it has low output.Yield and stability of 95-23 variety are all disappointing. HSC is not only a parameter for high yield but also a parameter of yield stability. It is accurate , simple and stable to appraise new broad bean variety with HSC .
