摘要:

为筛选出适宜于江苏西南部地区种植的饲用型大麦优良品种,本试验对39个不同大麦品种(系)的株高、茎粗、叶长、叶宽、分蘖数、第3节间长、第4节间长、穗长、穗宽、穗粒数、单株鲜重、单株干重、鲜草产量13个主要农艺性状及生产性能进行了测定,通过鲜草产量及单株干鲜重加权、并结合农艺性状评价筛选出生产及农艺性综合表现较优的10个大麦品种。进一步对筛选出的10个品种进行酸性洗涤纤维、中性洗涤纤维、粗蛋白(CP)、粗纤维、粗脂肪、相对饲喂价值(RFV)6个主要饲用品质指标的检测评估,并与其农艺及生产性能指标一起,通过相关性分析、主成分分析和隶属函数法综合评价不同大麦品种的表现。结果发现,所有供试大麦品种中Hv031、Hv013、Hv027、Hv017的鲜草产量较高(>50000 kg·hm-2),筛选出的10个适应性突出的大麦品种(系)在营养品质性状方面具有显著性差异,以Hv017、Hv030与Hv036的营养品质为较优(CP>10或RFV>100);通过对各个成分进行相关性分析与主成分分析表明第4节间长、株高、穗宽、第3节间长、茎粗与ADF可作为饲用大麦农艺与营养品质性状的重点评价指标;隶属函数综合评价得出Hv017、Hv027与Hv009这3个品种的表现较好,尤以Hv017最为突出,可作为江苏南京及周边地区推广种植的首选饲用大麦品种材料。

Abstract:

This study screened 39 varieties of forage barley (Hordeum vulgare) to identify elite varieties suitable for planting in the southwestern region of Jiangsu Province. Thirteen major agronomic traits: plant height, stem diameter, leaf length, leaf width, tiller number, the third internode length, the fourth internode length, spike length, spike width, kernel number per spike, fresh weight per plant, dry weight per plant, and fresh forage yield, were measured to determine agronomic performance. From the data, combined with agronomic evaluation, ten barley varieties with better multivariate scores for production and agronomic performance were identified. Further evaluation of six nutritional quality parameters, including acid detergent fiber (ADF), neutral detergent fiber (NDF), crude protein (CP), crude fiber (CF), ether extract (EE), and relative feeding value (RFV), was carried out for the ten varieties; and together with their production and agronomic trait indicators, the multivariate analysis used to identify the ten elite barley varieties included correlation analysis, principal component analysis, and membership function analysis. It was found that varieties Hv031, Hv013, Hv027, and Hv017 had the highest fresh herbage yields (>50000 kg?hm-2) among all tested barley varieties. Meanwhile, selection of ten varieties (lines) with better adaptability and nutritional quality traits, identified varieties Hv017, Hv030, and Hv036 as the most outstanding (CP>10 or RFV>100). The correlation analysis and principal component analysis of all measured traits indicated that the fourth internode length, plant height, spike width, the third internode length, stem diameter, and ADF can be used as key evaluation indicators for agronomic traits and nutritional quality traits in forage barley. The multivariate evaluation by membership function analysis demonstrated that Hv017, Hv027, and Hv009 were better for overall trait performance, with Hv017 being particularly outstanding. We therefore recommend that this variety be prioritized as the primary candidate variety for promotion and planting in Nanjing and surrounding areas of Jiangsu Province.
