Breeding of the new double-low NEA-cytoplasmic hybrid variety Chuanyou No.58 in Brassica napus L.

Abstract

Abstract: Improving the uniformity of hybrid-seed and coordinating high-yield and double-low and disease-resistance were the main rapeseed breeding tackling key problems. The NEA-cytoplasmic male sterility and its restorer line in Brassica napus L. bred by the authors were used. Testcrossing, backcrossing, selfing, crossing, quality-selecting, fertility-identifying, resistance-selecting and Strain-yield-comparing were the main methods. Chuanyou No.58, a double-low and high-yield NEA-CMS rapeseed hybrid ( Brassica napus L.), was developed from JA1 ( double-low NEA-CMS system ) × JR2 ( a double-low restorer ). JA1, whose sterile pollens per flower, sterile flowers per plant and sterile plants per group were all 100%, was differ from Pol.CMS, the main type of male sterile cytoplasm for rapeseed hybrid, due to the stable and thorough and never influenced by environment factors male sterility. Crossing fruitfulness of JA1 was very high. JR2, a NEA-restorer, was strong-restoring, pollen-plenty and easy-pollinating. F1-seed production technology of Chuanyou No.58 was uncomplicated. Chuanyou No.58 showed great hybrid superiority. The cultivar possessed the characteristics of desired agronomic quality, double-low, high yield, high oil content, early maturity, wide adaptability and acceptable resistance (tolerance ) to virus and S. sclerotiorum. It was released by Sichuan Crop Variety Approval Committee in October, 2005. The high-uniformity of hybrid-seed and the coordination of high-yield and double-low and disease-resistance were succeeded, due to the double-low three-line system of NEA and its restorers.
