Abstract

Confectionary sunflower (Helianthus annuus L.) has gained popularity due to its utilization in roasting as snacks, poultry, bird food, and bakery products. However, seed quality of confectionary sunflower differs from non-oil seed types. In the present study, 71 sunflower accessions were selected for the evaluation of seed quality traits. Significant genetic variability was observed for traits such as 100-seed mass and seed length, as indicated by high genotypic coefficients of variability. Genotypic correlation analysis revealed a positive association between 100-seed mass and seed size, protein content, and oleic acid content. Path coefficient analysis based on genotypic and phenotypic correlations suggested that accessions with high sugar content may be selected to develop superior germplasm for confectionary products. Biplot analysis was conducted to identify suitable accessions with favorable confectionary traits. Accessions ‘Hybrid 100’, ‘GOR101’, and ‘Odesskijj112’ exhibited high sugar content, while ‘Yawn’ demonstrated comparatively higher oleic acid content. Accessions ‘Vinimik 6931’ and ‘HA 305’ displayed high 100-seed mass, while seed length was greater in accessions ‘Comet’ and H. × multiflorous. Combining ability analysis were performed to assess the breeding value of accessions. ‘Comet’ exhibited the highest general combining ability (GCA) effects for seed yield per plant, head diameter and 100-achene mass; while ‘G.OR.104’ had positive GCA for achene yield per plant but negative combining ability for other traits. ‘Tenissiei’ displayed positive GCA for all traits. Among the testers, accession ‘Universal’ showed positive GCA for seed yield per plant, while ‘HA-292’ exhibited positive GCA for head diameter. The accessions with higher values for confectionary traits and positive general combining ability effects for yield related traits may be further exploited in confectionary sunflower breeding programs as parents.

糖果向日葵种质登录及其衍生杂交种的评估

糖果葵花（Helianthus annuus L.）因其可用作烤制点心、家禽、鸟类食品和烘焙产品而广受欢迎。然而，糖果葵的种子质量与非油用种子类型不同。本研究选取了 71 个向日葵品种进行种子质量性状评估。在 100 粒种子质量和种子长度等性状方面观察到了显著的遗传变异，这体现在较高的基因型变异系数上。基因型相关分析表明，100 粒种子质量与种子大小、蛋白质含量和油酸含量呈正相关。基于基因型和表型相关性的路径系数分析表明，可以选择含糖量高的品种来培育糖果产品的优良种质。通过双图分析，确定了具有良好糖果性状的合适品种。品种'杂交 100'、'GOR101'和'Odesskijj112'的含糖量较高，而'Yawn'的油酸含量相对较高。品种'Vinimik 6931'和'HA 305'的百粒种子质量较高，而品种'Comet'和 H. × multiflorous 的种子长度较长。通过组合能力分析评估了各品种的育种价值。彗星 "在单株种子产量、头径和百粒种子质量方面的一般组合能力（GCA）效应最高；而 "G.OR.104 "在单株瘦果产量方面的一般组合能力为正，但在其他性状方面的组合能力为负。Tenissiei'的所有性状的 GCA 均为正。在测试者中，'Universal'在单株种子产量方面的 GCA 为正，而'HA-292'在头径方面的 GCA 为正。在糖果向日葵育种计划中，糖果性状值较高且产量相关性状的一般组合能力效应为正的品种可作为亲本进一步利用。

期刊介绍： Genetic Resources and Crop Evolution is devoted to all aspects of plant genetic resources research. It publishes original articles in the fields of taxonomical, morphological, physiological, biochemical, genetical, cytological or ethnobotanical research of genetic resources and includes contributions to gene-bank management in a broad sense, that means to collecting, maintenance, evaluation, storage and documentation. Areas of particular interest include: -crop evolution -domestication -crop-weed relationships -related wild species -history of cultivated plants including palaeoethnobotany. Genetic Resources and Crop Evolution also publishes short communications, e.g. newly described crop taxa, nomenclatural notes, reports of collecting missions, evaluation results of gene-bank material etc. as well as book reviews of important publications in the field of genetic resources. Every volume will contain some review articles on actual problems. The journal is the internationalized continuation of the German periodical Die Kulturpflanze, published formerly by the Institute of Plant Genetics and Crop Plant Research at Gatersleben, Germany. All contributions are in the English language and are subject to peer reviewing.
