摘要:

为满足河北省夏播鲜食甜加糯玉米的产业需求,本研究系统阐述了新品种‘石甜糯8号’的选育过程、特征特性、高效栽培技术及推广模式。通过以自交系‘石糯6’为母本、‘石糯7’为父本组配杂交,结合区域试验、抗病性鉴定及品质分析,对该品种进行了全面评价。2021年和2022年区域试验中,‘石甜糯8号’鲜果穗平均产量分别为16191.00 kg/hm²和15540.00 kg/hm²,两年平均产量15865.05 kg/hm²,较对照‘万糯6号’增产7.20%。该品种中早熟,夏播生育期约80 d,籽粒呈紫白彩色,千粒重336 g,直链淀粉含量占淀粉总量的1.55%,口感兼具甜玉米的清甜和糯玉米的软糯。‘石甜糯8号’综合性状优良,适宜在河北省的鲜食糯玉米夏播区域推广种植,具有广阔的市场应用前景和良好的经济效益。

Abstract:

In order to meet the industrial demand of summer fresh sweet-waxy corn in Hebei Province, this study systematically expounded the breeding process, characteristics, high-efficiency cultivation techniques and promotion mode of the new variety ‘Shitiannuo 8’. The hybrid was developed by crossing the inbred line ‘Shi Nuo 6’ as the female parent with ‘Shi Nuo 7’ as the male parent. Variety evaluation was carried out through regional trials, disease resistance identification, and quality analysis. In the regional trials in 2021 and 2022, the average yield of fresh cobs was 16191.00 kg/hm2 and 15540.00 kg/hm2 respectively, with an average yield of 15865.05 kg/hm2 over the two-year period, representing a 7.20% increase compared to the control variety ‘Wan Nuo 6’. This variety is medium-early maturing, with a growth period of approximately 80 days for summer sowing. The grains are purple-white in color, with a 1000- grain weight of 336 g, and the amylose content accounts for 1.55% of the crude starch. ‘Shitiannuo 8’ has excellent comprehensive traits, is suitable for summer sowing in the fresh-eating waxy corn areas of Hebei Province, and has good promotion prospects.

Key words: sweet-waxy corn, ‘Shitiannuo No.8’, variety selection and breeding, promotion model
