Abstract
The invention relates to novel inbred rice lines designated A0044 and B0044, and the plants of inbred rice lines A0044 and B0044 as well as the rice plant and plant parts produced by the seed designated A0044. The invention also relates to methods of maintaining the male-sterile line A0044 by crossing it with the fertile line B0044 and to methods of producing hybrid rice plants by crossing inbred rice line A0044 with rice lines that act as pollen parents to restore fertility to the F1 plants. Further, the invention relates to hybrid rice plants in which inbred rice line A0044 is the female parent.
Claims12
Inbred Rice Seed designated A0044 and having ATCC Accession No. PTA-837.
An inbred rice plant having a genotype capable of expressing all the physiological and morphological characteristics of A0044, a representative sample of which has been deposited with American Type Culture Collection and having Accession No. PTA-837.
Inbred Rice Seed designated B0044 and having ATCC Accession No. PTA-836.
An inbred rice plant having a genotype capable of expressing all the physiological and morphological characteristics of B0044, a representative sample of which has been deposited with American Type Culture Collection and having Accession No. PTA-836.
A method of maintaining the seed of male-sterile inbred rice line A0044, a representative sample of which has been deposited with American Type Culture Collection and having Accession No. PTA-837, comprising the steps of:
- (a) planting in pollinating proximity seeds of rice inbred lines A0044 and rice inbred line B0044, a representative sample of which has been deposited with American Type Culture Collection and having Accession No. PTA-836;
- (b) cultivating rice plants resulting from the planting until the time the plants bear flowers;
- (c) allowing pollination of inbred line A0044 by inbred line B0044;
- (d) harvesting seeds produced on male-sterile plants of the inbred line A0044.
A method of producing hybrid rice having the characteristics of high yield comprising the steps of:
- (a) planting in pollinating proximity seeds of rice inbred line A0044, a representative sample of which has been deposited with American Type Culture Collection and having Accession No. PTA-837, and another inbred line;
- (b) cultivating rice plants resulting from the planting until the time the plants bear flowers;
- (c) allowing pollination of inbred line A0044 by the other inbred line;
- (d) harvesting seeds produced on male-sterile plants of the inbred line A0044.
A rice plant capable of expressing all the physiological and morphological characteristics of rice plants grown from rice seed designated A0044, a representative sample of which has been deposited with American Type Culture Collection and having Accession No. PTA-837.
