摘要
为探究适合云南省薏苡种植的新品种（系）,以提高云南薏苡种植的生产力水平。通过对10个薏苡品系在云南省文山地区进行生产力的比较试验,对薏苡农艺性状（生育期、株高、茎粗、有效分蘖数、单株总果数、百粒重等）进行比较鉴定与评价,并对其产量进行分析比较。结果表明：（1）有效分蘖数、单株总果数、百粒重与产量呈正相关,其中百粒重与产量的相关性显著;（2）YLO、Y7—1生育期较短,植株较矮,茎秆细,株型紧凑,抗倒伏性强,是理想的株型;（3）Y9—7、Y3—4、Y12—2（黑）为中晚熟品种,百粒重高、籽粒外观好、产量高;（4）YGL、‘文薏二号’为晚熟品种,生育期在150~155天之间,植株高、分蘖力强、茎秆粗、生物产量高,但经济产量较低;（5）从薏苡的综合性状、产量、适应性等指标来看,参试的品系Y9—7、Y3—4、Y12—2（黑）优势明显,更符合选育优质、高产的新品种（系）。
The study aims to explore new varieties of Coix suitable for cultivation in Yunnan Province, thus to improve the productivity level of Coix planted in Yunnan. By comparing test of 10 Coix lines that were planted in areas of Wenshan, Yunnan, agronomic traits （growth period, plant height, stem diameter, number of tillers per plant, total fruit number, hundred-kernel weight, etc.） were analyzed and yields were compared. The results showed that： （1） effective tiller number, total fruit number per plant and seed weight were positively correlated with yield, and the yield was significantly correlated with hundred-kernel weight; （2） lines of YLO and YT-1 had features such as shorter growing period, shorter plants, thin stems, compact plant type, lodging resistance, etc., both of them were ideal plant types; （3） Y9-7, Y3-4, and Y12-2 （black） were the late- maturing varieties, they had good features in hundred-kernel weight, grain appearance and yield; （4） YGL and Wen Yi II were late-maturing varieties, both of them had the growing period between 150 to 155 days, and showed good plant height, tillering ability, stem diameter and high biomass production, however, lower economic output; （5） the tested varieties （lines） Y9-7, Y3-4 and Y12-2 （black） had obvious advantages, and were in line with selection of high quality, high-yielding new varieties （lines） from comprehensive agronomic traits, yield, adaptation and other indicators.
