在水稻栽培和育种工作中,要增进品种的丰产性,主要在于统一处理好株型、穗数、粒数和粒重等因索的内在联系。笔者通过对水稻单株的粒重、有效穗数、单穗总粒数、单穗实粒数、千粒重、株高、茎粗、穗长、穗颈长、单株总分蘖数、叶面积、秆重等十二个性状进行相关分析,找出与单株粒重有显著相关的性状,作为育种工作中亲本的选配,杂交后代的选择,田间选种的依据。 材料和方法 试验在本所试验田进行。计栽培爱武68、南京11号、424、杂种谷、意大利、二九多、大粒珍珠矮、珍珠矮11号、托托黄、大粒溪丰、69—3、巨穗矮、阿宝稻、闽早4号、龙诗
In rice cultivation and breeding work, to enhance the high yield of varieties, mainly lies in the unified handling of plant type, the number of spikes, grain number and grain weight and other internal factors related to the cable. The author through the rice grain weight, number of effective spikes, single spike total grain number, single spike grain number, 1000 grain weight, plant height, stem diameter, spike length, panicle neck length, total tiller number per plant, leaf area, Stalk weight and other twelve traits correlation analysis to identify and grain weight per plant were significantly related traits as breeding parents in the selection of hybrids offspring selection field selection basis. Materials and methods of testing in our experimental field.
