在宁夏引黄灌区对６个草坪型多年生黑麦草品种的种子生产性能进行了研究。结果表明，不同品种间种子产量差异极显著（Ｐ＜０．０１），由高到低依次为Ｒｅｇａｌ＞Ｔａｒｇｅｔ＞Ｍｕｌｉｇａｎ＞Ｄｅｒｂｙ＞ＡＰＭ＞Ｓｅｖｉｌｅ，种子产量分别为１３８９．４、１２７９．９、１０７１．５、１０５１．７、９６３．６、６５２．６ｋｇ／ｈｍ２。因此认为，在宁夏平原灌溉条件下，多年生黑麦草种子生产以选用Ｒｅｇａｌ、Ｔａｒｇｅｔ最好，Ｍｕｌｉｇａｎ和Ｄｅｒｂｙ次之。而且，由于种子成熟期日照充足，降雨量低，故宁夏引黄灌区作为我国草坪型多年生黑麦草种子生产基地是完全可行的。
The seed production performance of 6 turf-type perennial ryegrass varieties was studied in Ningxia Yellow River Irrigation Area. The results showed that there was significant difference in seed yield among different varieties (P <0.01), with the order of Regal> Target> Muligan> Derby> APM> Sevile from high to low, respectively. The seed yield was 1389.4,1279.9,1071 .5, 1051.7, 963.6, 652.6 kg / hm2. Therefore, under the irrigation conditions of Ningxia Plain, the production of perennial ryegrass seeds is the best choice for the production of Regal, Target, followed by Muligan and Derby. Moreover, due to sufficient sunshine and low rainfall in maturity stage of seed, it is feasible for irrigated area of Ningxia Yellow River to serve as the production base of perennial ryegrass lawn in China.
