高粱糯质资源创新及其利用研究

利用高粱资源研究中新发掘和引进的糯质材料,通过有性杂交选育,农艺性状、抗病性鉴定和品质分析,选育出育种和生产急需的、综合农艺性状优良的糯质新种质L401A、L402A、1053A、1057A、1058A等5个不育系和R92、031069R、031038R等3个恢复系。利用新创资源组配了一批高产、综合农艺性状好的糯质高粱杂交组合。

Enhancement and Utilization of Glutinous Sorghum Germplasm

Using glutinous sorghum accessions screened out from our sorghum collections or introduced abroad as initial materials,hybridizations were made with elite sorghum germplasm with desired agronomic characters.Five male sterile lines(L401A,L402A,1053A,1057A and 1058A) and three restore lines(R92,031069R and 031038R) with desired agronomic characters and glutinous quality had been developed through evaluation of and selection for agronomic characters,disease resistance and grain quality.Several new glutinous hybrids with desired agronomic characters and high productivity have been developed using these new germplasm.
