宁春50号是宁夏农林科学院农作物研究所育成的高产优质广适小麦新品种,用品种鉴定、品比试验、区试试验、生产试验以及大面积生产示范、农田生产等多年多点试验示范对该品种进行了产量形成及稳定性分析,以期为当前高产小麦育种栽培提供借鉴。结果表明,宁春50号较对照宁春4号表现出了较高的产量;宁春50号稳定性与宁春4号相当,在2007年区试中宁春50号丰产稳产性都高于宁春4号,在稳定性产量上还有提高的潜力;在不同区域条件下,宁春50号和宁春4号产量及产量构成变化幅度基本一致,变化幅度最大的为穗粒数,千粒重次之,穗数最低;宁春50号产量及产量构成平均值较宁春4号都高,表明宁春50号具有较好的遗传特性,增产潜力明显;产量达到8 000kg/hm~2以上,平均穗数达到669.8×10~4穗/hm~2,平均穗粒数为30.9粒/穗,千粒重为42.8g,在5 000kg/hm~2到1 000kg/hm~2产量水平变化过程中,穗数、千粒重都呈现明显的递增趋势,而穗粒数变化趋势不明显;宁春50号产量增加与穗数、千粒重关系密切,相关系数分别为0.37、0.34,达到了极显著水平,与穗粒数关系未达到显著水平。宁春50号增产要提高穗数和千粒重,并采取相应的栽培管理措施。
Ningchun 50 is the Ningxia Academy of Agriculture and Forestry Institute of Crops bred high yield and quality of wide range of new wheat varieties, with varieties identification, product ratio test, the regional test, production test and large-scale production demonstration, farmland production and many years of demonstration The varieties were analyzed for yield formation and stability, with a view to provide reference for the current breeding of high yielding wheat. The results showed that Ningchun 50 showed higher yield than Ningchun 4; the stability of Ningchun 50 was similar to that of Ningchun 4, and the yield and stability of Ningchun 50 was higher than that of Ningchun 50 Ningchun No.4 had the potential to increase in the stable yield. Under the different regional conditions, the changes of the yield and yield components of Ningchun 50 and Ningchun 4 were basically the same. The variation range was the grain number per spike, grain weight per thousand Followed by the lowest number of spikes; Ningchun 50 yield and yield constitute an average of Ningchun No. 4 are higher, indicating that Ningchun 50 has good genetic characteristics, yield potential obvious; production reached 8 000kg / hm ~ 2 above , The average spike number reached 669.8 × 10 ~ 4 spikes / hm ~ 2, the average number of spikelets was 30.9 grains per spike and the grain weight per spike was 42.8g. During the change of the yield of 5 000kg / hm 2 ~1 000kg / hm ~ 2 , Spike number and 1000-grain weight all showed a clear trend of increasing while the trend of spike number was not obvious. The increase of yield of Ningchun 50 was closely related to spike number and 1000-grain weight, the correlation coefficients were 0.37,0.34 respectively, reaching the extremely significant level, The relationship between grain number did not reach significant level. Ningchun 50 yield to increase the number of spikes and 1000-grain weight, and take the appropriate cultivation and management measures.
