偏籼型籼粳交迟熟种“满仓５１５”具有大穗大粒特性，高抗稻瘟病，并对光温反应不敏感。１９９６年通过福建省审定，在１９９４、１９９５两年福建省产量区域试验中，满仓５１５比对照荆糯６号和汕优桂３２分别增产８．１７％和８．２６％。该品种选育成功表明杨守仁教授“理想株形与优势利用相结合”在偏籼型亚种间杂交育种的实现。
The indica-japonica late-maturing hybrid rice “Mancang 515” possesses the characteristics of big spike and big grain, high resistance to rice blast and insensitivity to light and temperature. In 1996, it passed the examination of Fujian Province. In the regional trial of Fujian Province in 1994 and 1995, the yield of 515 in full warehouse was 8.17% and 8.26% higher than that of Jinguuo 6 and Shanyougui 32 respectively. The success of the breed breeding proves that the combination of ideal plant shape and superior utilization by Professor Yang Shouren has realized the hybridization between indica type subspecies.
