采用“金字塔”筛选法,1980～1990年,人工接种辣椒品种资源1003份(次),(其中 CMV478份,TMV436份,CMV+TMV89份);筛选出的抗(耐)素材221份(次),其中抗 TMV84份,抗(耐)CMV101份,兼抗(耐)两种病毒的材料36(?)份。P2005584044、P2006683—4和 PRTC—1、PRTC—2四个抗源经“65”和“75”攻关组统一验收鉴定,是较好的抗源亲本,已提供全国攻关协作组应用。还初筛出具有优良园艺学性状的 F_1组合和抗源品系各8个,是有希望直接利用的优良材料。利用筛选出的抗源,先后配制了54个组合,经组合力测定,3个组合的病情指数明显低于对照而产量高于对照(吉农方椒)。
The “Pyramid” screening method was used. From 1980 to 1990, 1003 parts of pepper varieties were artificially inoculated, of which 478 were CMV, 438 were TMV, and 89 were CMV + TMV; 221 resistant (resistant) , Including anti-TMV84 parts, anti-resistant CMV101 parts, and anti- (resistant) two kinds of virus material 36 (?) Copies. P2005584044, P2006683-4 and PRTC-1, PRTC-2 four anti-source through the “65” and “75” research group unified acceptance identification, is a good anti-source parents, has provided the national research collaboration group. It also screened out the F_1 combinations with excellent horticultural traits and 8 lines of resistant strains each for good humor utilization. Using the screened resistance sources, 54 combinations were prepared successively. The determination of combinatorial force showed that the disease index of the three combinations was significantly lower than that of the control and the yield was higher than that of the control (Ji Nong Fang Jiao).
