The present invention provides use of a photoperiod-sensitive genic male sterility mutant of cotton in crossbreeding or hybrid seed production. The fertility of the photoperiod-sensitive genic male sterility mutant of cotton is influenced by the photoperiod. The photoperiod characteristic of the photoperiod-sensitive genic male sterility mutant of cotton is that, the photoperiod-sensitive genic male sterility mutant of cotton shows normal fertility when the illumination time is shorter than 11.5 h and shows genic male sterility when the illumination time is longer than 12 h; the photoperiod-sensitive genic male sterility mutant of cotton is in a fertility change period when the illumination time is in a range of 11.5-12 h and has less pollen. The photoperiod-sensitive genic male sterility mutant of cotton is PSM1, and/or a photoperiod-sensitive genic sterile line obtained through selective breeding of hybridized and/or backcrossed and/or self-bred offsprings of the PSM1.

The present invention discloses a method for producing a commercial non-GM tomato crop exhibiting at least one inheritable improved trait by exposing said population of plants to a predetermined light treatment regime, monitoring at least one trait of said tomato plants comparing to said control population and selecting the plants having the best improved trait.

The tomatoes obtained by the method of this invention exhibit an improved room temperature (17-27 C.) shelf life of at least 45 days after harvesting, as compared to about 10 days for untreated control tomatoes.

The disclosure provides compositions and methods for infecting a legume plant and/or increasing the yield of a legume plant by providing a population of light-activated, nitrogen-fixing bacteria by illuminating a population of nitrogen-fixing bacteria with a blue light and delivering to the legume plant the population of light-activated, nitrogen-fixing bacteria.

The present invention relates to a method for producing Cannabis sativa L. seed, and more particularly, to a method for producing Cannabis sativa L. seed for efficiently cultivating a low-narcotic cannabis variety, and when Cannabis sativa L. seeds produced by the production method are used, it is possible to cultivate cannabis female plants where female flowers are formed, and it is possible to improve the quantity of cannabis female flowers. Further, when a cannabis extract is prepared using the cannabis female flowers, it is possible to prepare a low-narcotic cannabis extract.
