Abstract: By the analyses of the main properties of 11 early Indica season rice varietieses lured by the NMU chemistry. It shows that NMU lures have some effect on main properties of the plant-height etc changing, but the results to different properties are different. The range of plant-height variation is the biggest, the secondary is the weight of single plant, it is minimum from sowing to heading. NMU lure have some qualities of certain directionality and single-minded. Among the 11 varieties, the chance of the duration shorten from sowing to heading and the increase of the number of the spikeletes per panical are bigger, and the raise of the 1000-grain weight, the rates of seed settting and the weight of single plant there is certain possibility too again; NMU lure has a high-efficient quality, it can combine the early-maturing, high yield and high quality organicly, it have solved the goal of the method of breeding of the routine difficult to reach; NMU has also peculiar quality , for example the glutinous variation appears in the later generation of Zaoxian 26. The later generation of Zhuqing has presented the appearance with relatively excellent quality. In addition, some peculiar variation type such as stay-green can also be gotten. It can be concluded: NMU and the lure technology become more effectively in the breeding and the improvement of rice varietieses.
