摘  要：
Qingza No.3 (B.napus L.),a pol cms three-line hybrid variety with very eary maturity and canola quality, was bred by Spring Rapeseed Research and Development Centre of Qinghai Province. In National Regional Trial of Spring Rapeseed, Qingza No.3 gave an average yield of 2 340.1㎏/hm~2 which outyielded the control variety Qingyou 241 (B.campestris L.) by 39.3%. In National Production Test, it showed yield of (2 407.5㎏/hm~2) which outyielded the control variety Qingyou 241 by 45.1%. Qingza No.3 gave average yield of (2 790.2㎏/hm~2) and 2 989kg/hm~2, which outyielded the control variety Qingyou 241 by 47.6% and 50.2% respectively in the Regional Test and Production Test of Qinghai Province. The erucic acid content in oil, glucosinoate content in mail and oil content in seed was 0.5%, 29.40μmol/g and 44.2% respectively. The ability of Qingza No.3 in resistance to Sclerotinia Sclerotiorum was much higher than that of the control variety Qingyou 241 and the growth duration was similar to Qingyou 241. Qingza No.3 is suitsble to be planted in the area of elevation 2 800～3 000m of Qinghai province and B.campestris production area of Inner Mongolia,Xinjiang, Gansu and Heilongjiang. It was registered by the Qinghai Crops Variety Approval Committee in 2001 and registered by National Crops Variety Approval Committee in 2003.
