The weight and oil percentage of 6684 grains from 3 kinds of micro endosperm corn ( Zea mays L.) were measured two times separately. The results showed that the oil content of 1 944 grains among them were higher than 20%,and 32 of 1 944 grains were higher than 25%,the highest was 26.84%. The correlation coefficients between the weight and oil percentage of single grain ( r 1,with degree of freedom,df =78),and between the mean grain weight and oil percentage of ears ( r 2,with df =14 and r 3,with...

The weight and oil percentage of 6684 grains from 3 kinds of micro endosperm corn ( Zea mays L.) were measured two times separately. The results showed that the oil content of 1 944 grains among them were higher than 20%,and 32 of 1 944 grains were higher than 25%,the highest was 26.84%. The correlation coefficients between the weight and oil percentage of single grain ( r 1,with degree of freedom,df =78),and between the mean grain weight and oil percentage of ears ( r 2,with df =14 and r 3,with df =64) were calculated. Three of them weren't significant at 0.05 level. So it is possible that the strains of micro endosperm corn with higher grain weight and higher oil content can be breeded on the basis of grains or/and ear selections. It can be expected that a new high oil corn type will be breeded successively in future.

分两批测定了 3种类型共 6 6 84粒微胚乳玉米 (ZeamaysL )的粒重和含油率。发现 194 4粒含油率高于 2 0 % ,其中有 32粒超过 2 5 % ,最高为 2 6 84 %。计算了单粒重与含油率 (df1=78)以及各果穗平均粒重与含油率 (df2 =14 ,df3 =6 4 )的相关系数 ,3个相关系数都未达显著水平。表明以籽粒或 (和 )以果穗为基础 ,选育既籽粒相对较重 ,又含油率相对较高的微胚乳超高油玉米品系 ,是完全可能的。有望培育出一种专用型油料玉米新作物。

The percent oil and several characters correlated with it were studied on micro endosperm corn. The results showed that there was extensively genetic variation for oil percent in these materials. The correlation coefficient (r) between the mean grain weight and percent oil wasn't significanteat at 0.05 level. But the r between the oil percent and the weight ratio of embryoto kernel and the r between the percent oil and the oil percent of embryo were significante at 0.01 level. And the r between the percent...

The percent oil and several characters correlated with it were studied on micro endosperm corn. The results showed that there was extensively genetic variation for oil percent in these materials. The correlation coefficient (r) between the mean grain weight and percent oil wasn't significanteat at 0.05 level. But the r between the oil percent and the weight ratio of embryoto kernel and the r between the percent oil and the oil percent of embryo were significante at 0.01 level. And the r between the percent oil of parents and their hybrid generation was also significant at 0.05 level. The possible prospects for using the germplasm of the micro endosperm corn were discussed.

对微胚乳玉米的含油率及其一些相关性状进行了研究。讨论了微胚乳玉米种质可能的利用前景。结果表明这批材料的含油率存在着广泛的遗传变异。含油率与粒重不存在显著的相关,但含油率与胚/籽粒干重,及胚含油率间存在极显著的正相关。亲本与杂交子代的含油率间也存在显著的正相关。

The inbreeding was conducted for three generations in corn and some new micro-endosperm super high oil lines were obtained. It was found that the oil content of inbred lines could be inherited. The mean oil content of S3 population was as high as(21.65 ±2.12)% and was higher 0.28% than S2 parent population's by means of selection of kernels and ears. The study of the correlation between the mean grain weight and oil content of ears showed that the correlation coefficient(r1=0.275) from 33 ears in...

The study of the correlation between the mean grain weight and oil content of ears showed that the correlation coefficient(r1=0.275) from 33 ears in S2 and the correlation coefficient (r2=-0.023) from 69 ears in S3 were all not significant at 0.05 level.

对一种新型微胚乳超高油玉米育种材料进行连续自交三代,结果发现,自交系的含油量能够遗传,通过对果穗和单粒的选择,S3群体平均含油量已达到(21.65±2.21)%,比S2留种群体含油量高,遗传进度为0.28%;对各果穗的平均粒重与含油量相关关系的研究发现,从S2选取的33个果穗计算的相关系数r1=0.275,未达到显著水平,S3选取69个果穗计算其相关系数r2=-0.023,也未达显著水平,这表明果穗的平均粒重与含油量之间没有显著的相关性。
