天麻不同种质资源自交及其杂交后代果实和种苗农艺性状分析
Analysis of fruit and seedling agronomic characters of different germplasm resources and self-pollinated and hybrid offsprings of Gastrodia elata
摘要
Abstract
Self-pollination and hybridization experiments were conducted on 12 germplasm resources of G.elata.The traits of the F0 generation,as well as those of the self-pollinated and hybrid Fl generations,were analyzed.The re-sults showed that the 12 germplasms of G.elata exhibited obvious differences in traits.In terms of tuber type,Gastrodia elata Bl.f.elata type was slender,with the ratio of length to width ranging from 1.94 to 2.50,while Gastrodia elata Bl.f.glauca S.Chow type was short and thick,with the ratio ranging from 1.82 to 2.07.In terms of bolting time,Gas-trodia elata Bl.f.glauca S.Chow bolted earliest,followed by Gastrodia elata Bl.f.elata.The bolting speed of these germplasms comfermed to the Logistics growth curve.The G.elata with blood-colored scape,which was original from Zhaotong,had the longest and thicker scape,while the number of fruit pods was below the medium level,Gastrodia ela-ta Bl.f.elata from Yichang had a shorter scape and the largest number of fruit pods.The fruit pod color of the hybrid F1,with Gastrodia elata Bl.f.glauca S.Chow serving as female parent and Gastrodia elata Bl.f.elata from Anhui serving as male parent,was more inclined to the male parent.The color of hybrid F1,which used Gastrodia elata Bl.f.elata(blood-colored scape type)serving as female parent and Gastrodia elata Bl.f.elata from Anhui serving as male parent,was more inclined to the female parent,indicating that the traits of the seeds in the hybrid F1 showed the rule of inheritance from maternal parent.The seed vitality of hybrid F1,which used Gastrodia elata Bl.f.elata(blood-colored scape type)as female parent,reached more than 98％.The shape of hybrid Fl immature tuber of Gastrodia elata Bl.f.glauca S.Chow,Gastrodia elata Bl.f.viridis makino and Gastrodia elata Bl.f.elata(blood-colored scape type)from different origins,which serving as female parent,was close to the slender strip of the male parent Gastrodia elata Bl.f.elata from Anhui.The Gastrodia elata Bl.f.elata hybrid F1 from different origins,which serving as female parent,was close to the male parent Gastrodia elata Bl.f.glauca S.Chow from Zhaotong and showed rounded and full shape.The hybrid F1 with Gastrodia elata Bl.f.elata from Anhui serving as female parent and Gastrodia elata Bl.f.glauca S.Chow from Zhaotong serving as male parent showed significant advantages in seed traits among all hybrid combinations.The F1 seed vigor of Gastrodia elata Bl.f.elata(blood-colored scape type)from Luquan serving as female parent and Gastrodia elata Bl.f.elata from Anhui serving as male parent was the highest.The immature tubers of F1 hybrid with Gastrodia elata Bl.f.elata from Sichuan as the female parent and Gastrodia elata Bl.f.glauca S.Chow from Zhao-tong as the male parent were more round and plump in shape compared to self pollinated immature tubers.关键词
