    Variety characteristics

    Plant characters and growth periodYouyan 924 is a bilinear hybrid of Brassica napus and semi-winter genic male sterility. The cotyledon of seedlings is reniform,and the interior leafis a little purple;during the seedling stage,it is suberect,the top cleft leaf is large,the leaf colour is green,and it has sumatriptan,the blade length is medium,the number of cleft leaves is 2-4 pairs,the vein is obvious,the leaf margin has sinuate denticles.The petal is yellow and lateral-pile,and its length is moderate.The color of seed is uneven faint yellow.In the regional trial,the growthvigor at seedling stage and bolting stage is strong and the consistency is good.Under the density of 34.5×104-40.5×104plants/hm2,the mean of the two-year regional trial(in Table 1)was as follows:plant height and branch height were 179.73 and 89.11 cm,respectively,available primary branches were 6.71 per plant,which was more than Zhongyouza 2 (CK)by 0.4 per plant,the main inflorescence lenth was 52.85 cm,the pod density was 1.23 pods/cm,the average effective pods per plant were 217.24 per plant,which was more than Zhongyouza 2(CK)by 6.45 per plant,seeds per pod were 19.86,1 000-seed weight was 3.76 g,the rapeseed yield per plant was 12.07 g.The abnormal plant(sterile plant)rates of the two years were respectively 0.48%and 1.2%,and the mean value was 0.84%.

    Table 1 The plant characters and economic characters of Youyan 924 in the two-year regional trial in the middle reaches of the Yangtze River

    Youyan 924 was directly sown from late September to early October(the sowing dates of the two years were respectively on September 29 and October 5),the average growth period was 220.3 d,which was more than CK Zhongyouza 2 by 1.6 d;in the production testing,the average growth period of Youyan 924 was 215.2 d,which was more than CK Zhongyouza 2 by 0.2 d.

    Variety resistanceFrom the average value of the two-year regional trial in Table 2,it was drawn that the sclerotiniose incidence and index of Youyan 924 were 5.24%and 3.28,respectively,which were respectively lower than Zhongyouza 2 by 1.96%and 0.87%;in the production testing,the sclerotiniose incidence and index were 5.13%and 2.02,respectively,which were respectively lower than Zhongyouza 2 by 1.18%and 1.43,indicating that the resistance of the variety to sclerotiniose was superior to that of Zhongyouza 2(CK).From Table 2,it also can be seen that the viral disease incidence and disease index of Youyan 924 were respectively lower than Zhongyouza 2 by 2.47%and 1.34,and in the production testing,they were also respectively lower than Zhongyouza 2 by 0.41%and 0.31,thus its resistance to viral disease was stronger than Zhongyouza 2.

    In the inoculation identification of disease resistance genetics group,the indexes of sclerotiniose of Youyan 924 in the two years were respectively 17.14 and 6.54 (in Table 3),and RRI values were respectively 0.49 and-0.45,the identification results of the two years were divided into low sensitivity and low resistance,showing that the resistance of Youyan 924 to sclerotiniose was comparable to that of Zhouyou 821.

    In the two years,Youyan 924 showed strong drought,waterlogging and lodging resistances (in Table 4),which were comparable to those of Zhongyouza 2;the average rate of freeze injury of Youyan 924 in the two years was 9.63%,which was lower than that of Zhongyouza 2 by 0.63%;and the average index of freeze injury of Youyan 924 in the two years was 2.86,which was higher than that of Zhongyouza 2 by 0.12.

    Quality performance

    In the two-year regional trial of the middle reaches of the Yangtze River,the oil rates of Youyan 924 were respectively 44.68%and 48.58%according to the sample analysis by National Regional Trial Group,and the average rate was 46.63%(in Table 7),which ranked the first in all varieties in the same group,and was higher than the average oil content of all the other varieties in the same group by 3.44 percent points,as well as was higher than that of Zhongyouza 2 in the same group by 5.14 percent points;in the production testing,the oilrate of Youyan 924 reached 49.21%;glucosinolate contents in the two years were respectively 18.33 and 22.21 μmol/g,thus the average glucosinolate content was 20.27 μmol/g;erucic acid contents in the seed in the two years were respectively 0.2%and 0.3%,thus the average content was 0.25%.

    Key Points of Cultivation Techniques

    Planting date

    The seedlings were grown in the middle of September and transplanted in mid-to-late October;the direct seeding was carried out during late September and early October.

    The transplanting density

    The transplanting densitywas among 9×104-12×104plants/hm2;ifdirect seeding,15×104-18 ×104plants/hm2seedlings can be leaved;high-density cultivation technique with mechanical sowing and mechanical harvesting can also be used,and the planting density can reach more than 37.5×104plants/hm2.

    Rational application of fertilizer

    Thefertilizingamountshouldbe2 250-3 000 kg/hm2,and the pure nitrogen that should be applied was more than 225 kg/hm2,N ∶P2O5∶K2O should be 1 ∶0.5∶0.9.It should be noticed that organic fertilizer was applied as base fertilizer,seedling weight,stem light and seedling root should be viewed as the reference for top dressing,the method of top dressing was urea-manure water mixture.

    Stressing on boron fertilizer application

    7.5-12 kg/hm2borax was applied as base fertilizer with the way of furrow dressing or it was mixed with water as topdressing,or foliage top-dressing of 0.3%borax solution was carried out at the seedling stage and bolting stage,the application of foliage top-dressing in the soil lacking boron and having a poor setting rate should be more emphasized.

    Preventing diseases,insect pests and weeds,and enhancing cultivation and management

    During the seedling stage,it should prevent aphid and cabbage caterpillar,etc.,moreover,the work of drought resistance and waterlogging drainage should be done timely.At the end of December,150 mg/L paclobutrazol solution was sprayed to improve the cold-resistant and lodging-resistant ability.During the flowering phase,combined with boron fertilizer application,40%dimethachlon was sprayed to prevent sclerotiniose.
