The results showed that the average life of the granted rice varieties was 10.013 years. With the increase of the age of plant variety rights, the probability of the same residual life Ttreaching x was smaller and smaller, the reliability lower and lower, while the probability of the variety rights becoming invalid became greater. The remaining useful life of a specific granted rice variety was closely related to the demonstration promotion age when the granted rice variety reached its maximum area and the appearance of alternative varieties, and when the demonstration promotion age of the granted rice variety reaching the one with the maximum area, the promotion area would be decreased once a new alternative variety appeared, correspondingly with the shortening of the remaining useful life of the variety. Therefore, Weibull Survival Analysis Method and Gaussian Model could describe the remaining useful life＇s time trend, as well as determine the remaining useful life of a concrete plant variety right, clarify the entire life time of varieties rights, and make the economic analysis of plant new varieties rights more accurate and reasonable.展开更多

[Method] ‘Jinmi 2＇ is a new super high-yielding hybrid mini watermelon developed by crossing J52 as female parent with X712 as a male parent. [Result] The variety is early maturing with 31 days fruit developing period and 108 days growth period. The average fruit weight is 2.4 kg and yield at 31 455 kg/hm2. The fruit is oblong shaped and it has a light green rind with jagged dark green stripes. The fresh is red, and tastes crisp and sweet, with center soluble solid content at 11.0% and margin at 7.8%. [Conclusion] The variety is suitable for production in most areas of Zhejiang.展开更多
