[Method] The yielding ability and yield stability of 5 varieties and 2 pioneer combinations in 5 test locations in Jiang- su Province in 2013-2015 were analyzed comprehensively. [Result] The environment effects and genotype x environment interaction effects of various tested varieties differed very significantly. It could be seen from various test locations that Mingyu 1301 and Sushi 51417 had very good yielding ability and yield stability, and were comprehensively assessed to be very good, Suyu 41 had very good yield stability and better yielding ability, and was comprehensively assessed to be good, while Suyu 29 and Suyu 39 showed instable yields in various locations and were greatly affected by environment, and thus should be planted in carefully-selected areas in extension. [Conclusion] This study provides theoretical foundation for breeding and extension of new varieties.展开更多

The resuits show that the lysogenic state has lower entropy production rate than lyric state, which provides an explanation on why the lysogenic state of A phage is so stable. We a/so notice that the entropy production rates of both lysogenic state and lyric state are lower than that of saddle-point and bifurcation state, which is consistent with the principle of minimum entropy production for living organism in nonequilibrium stationary state. Subsequently, the relations between CI and Cro degradation rates at two bifurcations and the changes of entropy production rate with CI and Cro degradation are deduced. The theory and method can be used to calculate entropy change in other molecular network.展开更多
