黄瓜早熟新品种沈春1号的选育

Breeding of New Early Maturing Cucumber Variety Shenchun No.1

[目的]介绍黄瓜早熟新品种沈春1号。[方法]综述沈春1号的选育过程、产量表现、特征特性、抗病性及其栽培要点。[结果]沈春1号是沈阳市农业科学院利用沈9829和沈9830杂交而成,瓜长约30 cm,高抗霜霉病,兼抗白粉病和枯萎病,雌花率55%左右,前期产量高,适合春季栽培,2005年通过辽宁省非主要农作物品种审定委员会审定,适宜在沈阳、大连、吉林及山东、河北等地种植。在品种比较试验中,虽总产量相差不大,但其前期产量比津优4号增加16.3%,区域试验中3个试点的前期产量均较高。[结论]该研究为沈春1号的推广应用提供了依据。

[Objective] The purpose was to introduce the new early maturing cucumber variety Shenchun 1. [Method] The breeding process, yield performance, characteristics, disease resistance and cultivation points of Shenchun 1 were summed up. [Result] Shenchun 1 was bred by crossing Shen 9829 with Shen 9830 by Shenyang Acadenry of Agricultural Sciences. Its fruit length was about 30 cm. It was high resistant to downy mildew and resistant to powdery mildew and wilt disease. Its pistillate flower rate was about 55% and the yield was high in its early growth stage, so it was suitable for cultivation in spring. It ,was examined and approved by Non - main Crops Variety Approval Committee of Liaoning Province in 2005. It was suitable for planting in Shenyang, Dalian, Jilin, Shandong, Hebei etc. In the variety comparative trial, compared with Jinyou 4, though their total yields had little difference, the yield of Shenchu 1 in its early growth stage increased 16.3%. The yields in its early growth stage in 3 tested spots in regional trial were comparatively high. [Conclusion] The research provided foundation for the popularization and application of Shenchun 1.
