摘要

为了改善冬季豌豆理想农艺性状的组合，在NARDI Fundulea(南罗马尼亚)进行了为期三年(2017-2019年)的籽粒产量、种子蛋白质含量、千粒重(TGW)、早熟性、高度、抗寒性和种子尺寸之间的关系评估。图像分析是评估种子直径、密度和体积等参数的有效工具。籽粒总重与抗寒性(r=0.69)、粒体积和粒直径(r=0.70)呈极显著相关。冬寒性与任一性状、粒体积与粒直径的相关系数最高(r=0.76)。鉴定出冬豌豆品系12038MT2、13008MT28-1、13002MT、~ 12004MT2、12032MT1和13008MT37，主要来源于冬×春杂交组合，具有较好的农艺性状，对产量和抗寒性有较好的影响。

Relation of Quantitative Traits in Winter Peas (Pisum sativum L.)

In order to improve the combination of desirable agronomic traits in winter peas, relation between grain yield, seed protein content, thousand grains weight (TGW), earliness, height, winter hardiness and seed dimension has been evaluated at NARDI Fundulea (South Romania) over three years (2017-2019). Image analysis proved to be an useful tool to assess the seed parameters such as diameter, density and volume. Very significant correlations between TGW and winter hardiness (r=0.69), grain volume and grain diameter (r=0.70), were found. The highest values of coefficient of correlation were registered for the trait combinations: winter hardiness and either, grain volume and grain diameter (r=0.76). Were identified winter peas lines 12038MT2, 13008MT28-1, 13002MT, to 12004MT2, 12032MT1 and 13008MT37, mainly derived from winter x spring crosses, that combine desirable agronomic traits, with a good impact on yield and winter hardiness.

期刊介绍： The Journal ROMANIAN AGRICULTURAL RESEARCH is an “open access” one, which publishes original articles, short communications, presenting new scientific results – theoretical, experimental and technical – on plant breeding and genetics, physiology, biotechnology, mineral nutrition and plant protection, in field crops. Reviews on up-to date subjects and recent research, preferably from Eastern Europe, may also be published.
