| Wheat is the main grain crop in Nanyang City.Its annual planting area is above 900million mu,and its output accounts for 1/2 of grain output in the region.To this end,we identified 193 new wheat lines introduced to Nanyang City from 2015 to 2017.Nine strains were selected from MS134,10-19,Xi Nong 612,1373131,and Xinong 238,HP72,Hm118,10105-23-2-7,and Xinong 173.For these 9 strains,once again selected as wheat cultivars,such as stem length,number of secondary roots,plant height,cold resistance,disease resistance,yield components,yield and other agronomic traits,the wheat suitable for planting in Nanyang was selected.The new varieties will provide more wheat varieties for farmers in Nanyang City.In this experiment study,the following results were obtained:1.Four new wheat lines 1370131,10-19,Xi Nong 612 and Xi Nong 173 suitable for planting in Nanyang region were selected through analysis of the yield and comprehensive traits of the 9 new strains tested.The yield increased by 4.05 compared with Zhoumai 18,1.63%,1.38%and 1.03%,which increased by 8.23%,5.72%,5.46%and 5.09%compared with Handan 4110.The number of panicles of the yield components was 214,000 new panicles/hm~2,1.278 million panicles/hm2,1.864 million panicle/hm~2 and 1.671 million panicle/hm~2 higher than Zhoumai 18,and the number of panicles per spike was 1.88 and 1.43,respectively,compared with Zhoumai 18.0.85 tablets and 3.96 tablets.Plant height is lower than the control,about 78cm.2.The resistance survey results showed that the four new wheat lines had strong resistance to cold and disease,and the year of stripe rust was mildly susceptible.3.The results of the growth period survey showed that the growth period of Xinong 173was 246 days,which was 18 days later than Zhou Mai,which was 3 days longer than the expansive 4110.The growth period of 1373131,10-19 and Xinong 612 was 247 days.Compared with Zhou Mai 18 nights 3 days,compared with 4110 nights 4 days.The above test materials are suitable for planting in Nanyang area. |
