利用玉米染色体畸变选育A型细胞质不育系的研究
0
()
摘要:
本文研究了利用玉米重——复缺失的染色体,选育新型质不育系,报道了核质不育会互相转变的大量试验结果,选育出一些不育系,并通过和大量自交系杂交的育性反应,断定它是一种抗性病强、育性稳定的质不育,并且不同于T、S、C三个类群,而是一种新型的质不育,定名为A型(或AA型)。利用这些不育系配制出较好的杂交组合,可供生产上利用。

STUDY ON THE SELECTION OF CYTOPLASMiC STERILE LINE OF TYPE A BY CHROMOSOME ABERRATED CORN
()
Abstract:
The present paper deals with the selection of new type cytoplasmic sterile line by chromosomal duplication-deficiency of corn. Some sterility were determinea as a highly disease-resistent and stably sterile one. This sterility is different from the tyeps of T, S, and C, and is a new type of sterility, named type A or AA. Better hybrid combinations can be obtained with such sterile lines.
Key words:  Corn,Cytoplasmic sterility,Chromosomal aberration.
