Yield performance, cultivation characteristics of Sumian 29, and its selection and breeding process were introduced in the paper. Regional tests from 2010 to 2011 in Jiangsu Province showed that seed cotton yield and lint yield averaged 4 185 and 1 737 kg/hm2, and increased by 10.6% and 8.5% respectively, when compared with control （Siza 3）. In production test, seed cotton yield and lint yield of Sumian 29 averaged 4 176 and 1 744.5 kg/hm2, respectively. Sumian 29 had high resistance to cotton bollworm, and also resistance to Fusarium wilt and Verticillium wilt of cotton. All of its fiber qualities achieved National Standard III and above. Sumian 29 has good application prospects.展开更多

[Method] The characteristics, yields, quality, application range and use of Huaimai No.29 were introduced and the cultivation technology was concluded. [Result] Huaimai No.29 is cultivated with Huaimai No.20 as a female parent and Mianyang No.04254 as a male parent, it is a semi-winter variety, and matures later, with yield of 7.5-9.0 t/hm2. The variety is suitable to be grown in Henan Province, northern areas of Anhui Province and Jiangsu Province, the central Shaanxi plain, and Heze, Shandong Province. The ears are spindle-shaped and seeds grow quite well. The thousand-seed weight is in the range of 40-42 g, and it is suitable to be sown in early or middle October in Huaibei and late October in the area along Huaihe River. The basic seedlings maintain in the range of 1.80-2.70 million per hm2. [Conclusion] Huaimai No.29 is of high yield and high tolerance against coldness. The comprehensive characters performed good. The variety was approved by our country in 2009 and numbered as nation-approved wheat No.2009010. It has been proved that the variety can be planted in Huaibei areas or the areas along Huai River.展开更多
