13个小豆新品系在广西地区的引种试验

Introduction trial of thirteen new adzuki bean lines in Guangxi

  • 摘要: 【目的】筛选适合广西种植的小豆新品系,为广西发展小豆生产提供优良品种。【方法】以小豆大粒品种京农6号为对照(CK),对13个小豆新品系进行两年引种试验,综合评价各品系的主要农艺性状、产量及抗性等。【结果】13个参试品系均表现早中熟,生育天数78.0~83.5 d;株高28.58~46.98 cm,主茎节数11.5~14.1节,主茎分枝1.0~2.0个,单株荚数20.5~31.2个,荚长7.3~9.8 cm,单荚粒数6.1~7.7粒,百粒重12.96~18.19 g。各参试品系两年干籽粒平均产量为1348.60~1992.79 kg/ha,有6个品系干籽粒产量高于CK,其中冀红0007-5、冀红0004-10和品红05203比CK增产10.00%以上;有7个品系干籽粒平均产量低于CK,其中保200424、唐红2009-73、苏小豆12-1、龙28-324和唐红0809-1较CK减产超过10.00%。所有品系均为直立株型,不裂荚;豆粒除保红200624为黄色外,其余均为红色;粒形除龙27-096为长圆柱形外,其余均为短圆柱形;两年试验中各品系均表现出较好的抗旱性、抗倒伏性及抗花叶病毒病性。【结论】小豆新品系冀红0007-5、冀红0004-10、冀红0001-15和同红2号产量较高、综合农艺性状优良且抗性较好,适合在广西南宁及周边生态环境相似的地区推广种植。

     

    Abstract: ObjectiveNew lines of adzuki bean that were suitable for planting in Guangxi were selected, in order to provide fine varieties for production of adzuki bean in Guangxi. MethodThirteen new lines of adzuki bean were intro-duced, and tested in two years, so as to evaluate comprehensively their main agronomic traits, yield, resistance, with large-seed variety Jingnong 6 as control(CK). ResultThirteen tested lines showed early or middle mature characteris-tic, growth period was 78.0-83.5 d, plant height ranged from 28.58 to 46.98 cm, nod number and branch number per main stem were 11.5-14.1 and 1.0-2.0, respectively, pod number per plant was 20.5-31.2, pod length was 7.3-9.8 cm, seed number per pod were 6.1-7.7, and 100-seed weight was 12.96-18.19 g. Average dry seed yields of tested lines were 1348.60-1992.79 kg/ha in two years, and dry seed yields of six tested lines were higher than that of CK, especially Jihong 0007-5, Jihong 0004-10 and Pinhong 05203 with increment of above 10.00%, but dry seed yields of other 7 lines were lower than that of CK, especially Bao 200424, Tanghong 2009-73, Suxiaodou 12-1, Long 28-324, Tanghong 0809-1 with decrement of above 10.00%. The tested lines were characterized by erect plant, indehiscent pod, red seed and short cylindrical seed, except Baohong 200624 with yellow seeds and Long 27-096 with long cylindrical seed. And all the tes-ted lines showed good resistance to drought, lodging and bean common mosaic virus(BCMV) disease in two-year trial.ConclusionFour new adzuki bean lines viz., Jihong 0007-5, Jihong 0004-10, Jihong 0001-15 and Tonghong 2 are characterized by high yield, excellent agronomic traits and good resistance, so which are suitable for planting in Nanning, Guangxi and some regions with similar environment.
