绿豆新品种“凤绿3号”的选育及栽培技术

Breeding and Cultivation Techniques of a New Mung Bean Variety'Fenglyu No.3'

“凤绿3号”是安徽科技学院从采自湖南郴州的野生绿豆资源中获得的自然变异单株,经多年系统选育形成的新品系,于2022年通过安徽省非主要农作物品种鉴定登记委员会审定,审定编号为皖品鉴登字第2108017。介绍了“凤绿3号”的选育过程、特征性状、田间试验情况和栽培技术要点。在2018—2021年连续几年的田间品比试验中,“凤绿3号”表现出明显的生长优势、产量优势和抗逆性能,其鲜草生物量平均达18583.0 kg/hm^(2),比对照铜山小绿豆增产19.4%,种子产量平均为2457.0 kg/hm^(2),与对照铜山小绿豆相当;在区域试验中,“凤绿3号”的平均鲜草重18886.5 kg/hm^(2),比对照高19.6%,平均种子产量2314.5 kg/hm^(2),与对照相当;同时,该品系鲜草的游离氨基酸和粗脂肪比对照铜山小绿豆增加了10%以上,粗纤维含量降低了5.68%,其干草的氮磷钾养分含量与对照基本持平,具备较高的饲用价值、饲用适口性和肥用价值。

'Fenglyu No.3'is a new mung bean variety bred from a natural mutant of wild mung bean germplasm collected from Chenzhou,Hunan Province in 2014 through years of systematic breeding by Anhui Science and Technology University.It was approved by the Anhui Crop Variety Certification Committee in 2022(Authorized number:Wanpinjian 2108017).This paper has introduced its breeding process,characteristics and traits,field performance and key cultivation techniques.In the field comparative experiment conducted for three consecutive years from 2018 to 2021,'Fenglyu No.3'presented obvious advantages in growth,yield and stress resistance,averagely reaching 18,583.0 kg/hm^(2)of biomass of fresh grass,19.4%higher than'TongshanXiaolyudou'(CK),and 2,457.0 kg/hm^(2)of seed yield,equivalent to CK.In regional test,'Fenglyu No.3'averagely produced 18,886.5 kg/hm^(2)of fresh grass,19.6%higher than CK,and 2,314.5 kg/hm^(2)of seed yield,equivalent to CK.Additionally,in its fresh grass,the content of free amino acids and crude fat increased by over 10%,and crude fiber content decreased by 5.68%in contrast to CK,while the level of N,P and K nutrients in its hay was basically equivalent to CK,so it has high feeding value,palatability and fertilizer value.
