Two line and three line sterile lines with independent property rights
A new type of maintainer line and a pair of male sterile lines were bred by using a rice blast resistant maintainer line Digu B, an early maturing high-quality Yue 4B and a high-quality conventional rice.
The plant height of the sterile line is about 59.8cm,
The stem is medium thick and tough, and the sword leaf is long, straight, narrow and concave.
The tillering ability is strong, and the ear rate is high,
The sowing period is about 68 days.
The sterile plant rate is 100%, and the sterility is 99.99%,
The pollen was mainly degenerated.
Good flowering habit and high stigma exsertion rate.
Resistance: moderately resistant to rice blast and bacterial blight,
The long grain type of rice is superior in comprehensive quality. The brown rice rate is 79.0%, the milled rice rate is 69.2%, the gel consistency is 82mm, and the chalky grain rate and chalkiness are low.
Qianfengyou 877, Qianfengyou 559 and other series of new varieties have been successfully combined into the national and provincial regional trials for approval, which is particularly suitable for the combination of high-quality, super high-yield, medium and late maturing middle rice in the upper reaches of the Yangtze River.
