Abstract

Abstract: In order to enrich genetic diversity of wheat and provide germplasm for genetic improvement,it was analyzed that the performance of plant height (PH),spikes per plant (SPP),spike length (SL),spikelets,kernels per spike (KPS),1 000-kernel weight (TKW) of 104 Slovak germplasm resources in wheat.It was showed that:higher PH,bigger SL and lower TKW than check varieties,it was recheved extremely significance of 0.01 levels during PH,SL and TKW;The range of coefficient variation during 6 agronomic traits were 0.08-0.37,the order was SPP>PH=KPS>TKW>SL>spikelets;The significant test results of 64 winter wheat and 40 spring wheat were that TKW achieved extremely significant level of 0.01,PH and KPS achieved significant level of 0.05,SPP,SL and spikelets were not differential;The correlation analysis indicated that PH and SPP,PH and SL,SL and spikelets,SL and KPS,spikelets and KPS were extremely significant positive correlation,SL and TKW,KPS and TKW were significant positive correlation;These germplasms were classified 4 categories by cluster analysis;3 selected germplasm resources whose comprehensive agronomic traits were outstanding,they were used as parent materials in the wheat planting fields of Huanghe and Huaihe Rivers for wheat genetic improvement.
