Benefits of technology

This patented technology allows two types of plants called Japanese indigo or Japonica be mixed together during their growing period by placing them into different environments at specific temperatures. When they start out from one type but then transition back towards another due to factors like poor weather conditions such as rain or snow. By doing this, it can increase both crop yields and improve overall plant health.

Problems solved by technology

This patented technical problem addressed by this patents relates to improving the efficiency with which Japanese rice (Japanese barbari) seeds germinate during their growth process without losing too much or even causing abnormalities such as lack of pollen grains on top layers of plants' leaves.

Embodiment 1

[0035] The embodiment of the present invention provides a kind of method that hybrid japonica rice seed production male parent and female parent meet at flower time, the method comprises:

[0036] The restorer japonica rice was used as the male parent, and the sterile japonica rice was used as the female parent;

[0037] The male parent and the female parent were respectively placed in an environment with an air humidity of 80% and a temperature of 28° C. when pollinating. For ease of operation, the male parent and the female parent can be placed in the above-mentioned environment before the flowering period, so as to ensure that both the male parent and the female parent can grow well in this environment during pollination.

[0038] Specifically, the male parent is Fan 14 and the female parent is Shen 9A, and the hybrid japonica rice Huayou 14 was obtained.

[0039] Specifically, both the male parent and the female parent were planted in the southeastern region of my country...

Embodiment 2

[0043] The embodiment of the present invention provides a kind of method that hybrid japonica rice seed production male parent and female parent meet at flower time, the method comprises:

[0044] The restorer japonica rice was used as the male parent, and the sterile japonica rice was used as the female parent;

[0045] The male parent and the female parent were respectively placed in an environment with an air humidity of 85% and a temperature of 32° C. when pollinating. For ease of operation, the male parent and the female parent can be placed in the above-mentioned environment before the flowering period, so as to ensure that both the male parent and the female parent can grow well in this environment during pollination.

[0046] Specifically, the male parent is Fan 14, the female parent is Shen 9A, and the hybrid japonica rice obtained is Huayou 14.

[0047] Specifically, both the male parent and the female parent were planted in the southeastern region of my country.

Embodiment 3

[0055] The embodiment of the present invention provides a kind of method that hybrid japonica rice seed production male parent and female parent meet at flower time, the method comprises:

[0056] The restorer japonica rice was used as the male parent, and the sterile japonica rice was used as the female parent;

[0057] The male parent and the female parent were respectively placed in an environment with an air humidity of 95% and a temperature of 30° C. when pollinating. For ease of operation, the male parent and the female parent can be placed in the above-mentioned environment before the flowering period, so as to ensure that both the male parent and the female parent can grow well in this environment during pollination.

[0058] Specifically, the male parent is R19, the female parent is L6A, and the hybrid japonica rice obtained is Tianlongyou 619.

[0059] Specifically, both the male parent and the female parent were planted in the southeastern region of my country.

Abstract

The invention discloses a hybrid japonica rice seed production male parent and female parent flowering time meeting method. The hybrid japonica rice seed production male parent and female parent flowering time meeting method comprises the following steps: restorer-line japonica rice is taken as a male parent, and sterile-line japonica rice is taken as a female parent; the male parent and the female parent are placed in an environment with the air humidity A of being greater than or equal to 80% and less than or equal to 95% and the temperature of 28-32 DEG C during pollination. The environmentwith the air humidity being greater than 80% and the temperature of 28-32 DEG C provides an optimal flowering environment for male parents and female parents for hybrid japonica rice seed production,so that the flowering time of the female parents growing in the environment is centralized and is 20 minutes earlier, the flowering time of the male parents and the female parents for seed productionis matched, and the fertilization probability and the maturing rate of the female parents are further increased.
