Abstract
[Objective]To study the variation tendency of tested wheat trial varieties in the preliminary experiment of wheat water and soil group from the North of Yellow and Huai Valley of China from 2010 to 2014 years and pro-vide theoretical basis for the successful development of the consortium work ,provide a new varieties breeding ,select the tested varieties .[Methods]The varieties of the top 30% in yield were selected in the preliminary experiment of wheat water and soil group from the North of Yellow and Huai Valley of China from 2010 to 2014 years and calcu-lated the average value of the principal characters for every variety in each year .According to this result ,principal characters of the tested varieties during 5 years were compared and analyzed .[Results]The results showed that :the yields of tested varieties exist obvious fluctuations;the yields sustained to decline for three years after replacing the control varieties in 2012 following with a breakthrough leap;the spike number per mu showed a steady increase trend after the replacement of control varieties;Kernels per spike of the tested varieties appeared a tortuous descending trend with cumulative reduction of 3.47 grains during 5 years and averagely decreasing 0.69 grains per year;TKW (Thousand Kernel Weight) appeared a tortuous rising trend with cumulative increasing of 3.24 gram during 5 years and averagely increasing 0.65 gram per year .Plant height appeared a tortuous rising trend with cumulative increasing of 5. 35 cm during 5 years and averagely increasing 1. 07 cm per year;grow th period appeared a tortuous descending trend with cumulative reduction of 7.3 days during 4 years;the maturing phase was mainly at level 1 ,and had a trend to change to level 3;the growth habit was mainly at level 3 accounting for more than 75% tested varieties .[Conclusion]The new wheat varieties in the preliminary experiment from the North of Yellow and Huai Valley of China had the trends to steady spike number ,increase grain weight and plant height and reduce grow th period from 2010 to 2014 .关键词
