Observations were made on the morphology of floral organs inmale sterile rapes,B.chinensis L.and B.napus L..It was foundthat their floral organs were different in morphology and fertility.On the basis of morphological features,the male sterile plants couldbe classified into six types.The completely male sterile type withabortive anthers was considered of practical value and described indetail.The relation between the morphological variation of floralorgans and the degree of fertility was analysed and a few criteriafor selecting effective male steriles were suggested.These include(1)stable male sterile flowers mainly with anthers light in color ornearly necrotic and flat in shape,(2)good fertile pistils with abun-dant pod—bearing and seed—setting ability,and(3)apparently normaldevelopment of other floral parts.For selecting effective male sterilelines,the breeding methods were suggested by the author.To theauthor's opinion,the available material A_2I could be used to makehybrid rapes for breeding purpose,

对白菜型油莱(B.chinensis L)和甘蓝型油菜(B.napus L)雄性不育的花器形态进行了大量观测,结果表明:雄性不育油菜的花器存在着多种形态和育性程度的变异,初步可以分为六种花器类型。本文叙述了其中有实用价值的败药不育型的花器形态特征,分析了花器形态变异与育性的关系,提出了选育有效雄性不育油菜的花器形态指标:1.雄蕊不育性彻底稳定(以花药色浅呈坏死色泽,花药扁平即侧面无外凸增厚为主要特征。);2.雄蕊可育性好,自然结角结籽率高;3.其它花器官形态功能接近正常。对油菜有效雄性不育的选育方法也作了介绍,指出 A_2I 是选育有效雄性不育系的主要研究材料。

The photometry indexes and the chromaticity indexes of seedcoatcolot of B.napus L.were quantitatively measured by spectrum analysis,and the variation of seedcoat color was divided into 8 gradations bybiometrics on the basis of these indexes.The quantitative differencebetween the two neighboring grades is 5 NBS units of color differencethe higher gradation,the deeper seedcoat color.The oil contents of41 seed samples with different seedcoat color,which were collectedfrom 41 seed sample with different seedcoat...

The photometry indexes and the chromaticity indexes of seedcoatcolot of B.napus L.were quantitatively measured by spectrum analysis,and the variation of seedcoat color was divided into 8 gradations bybiometrics on the basis of these indexes.The quantitative differencebetween the two neighboring grades is 5 NBS units of color differencethe higher gradation,the deeper seedcoat color.The oil contents of41 seed samples with different seedcoat color,which were collectedfrom 41 seed sample with different seedcoat color,which were collected913 single plant of five different origins were determined by YG-2type Soxhlet's extractor.From the analysis of correlation and regression,it indicated that the-re were significant negative correlation between the seedcoat color andoil contents in the seed materials with the same genetic background〔r=(-0.408)-(-0.662)〕.The averaged oil contents of yellow seeds was1.54—4.26% higher than non-yellow seeds.When seedcoat color grada-tions decreased by one grade,the oil contents increased 0.65%.From thepreliminary microscopic observation and analysis on the sections of seed-coat in three samples with different origins,it indicated that the varia-tion of seedcoat thickness is one of the main reasons causing the ne-gative correlation between the seedcoat color and oil contents.

通过光谱分析法定量测量了甘蓝型油菜(B.napus,L.)种子表面颜色的光度学和色度学指标,把甘蓝型油菜种皮颜色的变异分为8级,使相邻两级之间相差5个 NBS 色差单位。级别愈高,颜色愈深。通过相关和回归分析表明,在相同的遗传背景中,甘蓝型油菜种皮颜色与种籽含油量之间存在着显著负相关〔r=(-0.408)-(-0.662)〕。黄籽平均含油量比非黄籽(黑籽或紫红籽)高1.54~4.26%。种皮颜色每降低一个级别时,种籽含油量将相应地提高0.65%。种皮切片的初步观测表明,种皮厚度的改变是造成种皮颜色与种子含油量相互变化的决定因素之一。

Based on the analysis of the origin of Brassica napus L, and of the diagram distribution and heredity tendency of self-compatibility variation in five cultivars populations, the authors hold that the stability in heredity of self-incomptibility lines can be bred from population the self-compatibility of which varies in considerable degrees, and suppose that self-incompatibility of a given cultivar of B.napus L. is controlled by a few pair of alleles, whose effect may be mainly non-addilive, but the...

Based on the analysis of the origin of Brassica napus L, and of the diagram distribution and heredity tendency of self-compatibility variation in five cultivars populations, the authors hold that the stability in heredity of self-incomptibility lines can be bred from population the self-compatibility of which varies in considerable degrees, and suppose that self-incompatibility of a given cultivar of B.napus L. is controlled by a few pair of alleles, whose effect may be mainly non-addilive, but the modifying effect of polygenes cannot be ruled out.

根据对甘蓝型油菜(B.napus L.)的起源以及5个品种群体自交亲和性变异的分布及其遗传趋势的分析,认为在自交亲和性变异较大的群体中是能够选育出遗传性稳定的自交不亲和系的,并推测在甘蓝型油菜中的某一特定品种的自交亲和性是由少数几对等位基因控制的,其效应可能主要是非加性的,但也不排除一些微效基因的修饰作用。
