Breeding a plant with itself

How much variation would there be in the offspring of a plant that was pollinated with itself with female pollen?

a female cannot pollinate itself.... unless you are refering to the acid thing that u put on the stem to induce a hermaphrodite node. but assuming you that you pollinated a female plant w/ its own male pollen(its a hermie). you should get only females and hermies with the seeds from it. The variation could depend greatly. its really all by chance. when the gametes combine and split and stuff genetic recombonation occurs when the genes basically get crossed over. some stuff will be similar. some the same. some completely diff. really not telling. prolly similar potency, height and other basic things.

If you had a female and used acid or asprin to induce male flowers it will produce female pollen. While the manufacturer claims that this will produce 100% female seeds, that's probaly a bit optimistic, and aimed at building there sales. Of course the odds say there will be some hermies.
Peace

Thanks, but you didnt answer my question.

Dutch Passion Feminised Seeds (text taken from Dutch passion "feminized seeds")

In an experiment done in 1999 we grew 15 varieties of "feminized" seeds. We started with 30 seeds per variety. The goals were: 1) to determine the percentages of female, male, and hermaphroditic plants. 2) to compare the uniformity (homogeneity) among plants from "feminized" seeds with those grown from "regular" seeds.

1. The results were excellent. Nine out of fifteen varieties had 100% female offspring. Percentages of female plants from the other 6 varieties were between 80 and 90%. These plants were all hermaphrodites, producing their male flowers at the end of their lifecycle. Seed-setting hardly took place. No males were found.

2. Approximately 70% of the plants of varieties grown from "feminized" seeds were far more uniform than plants grown from "regular" seeds of the same variety. About 20% of the varieties were a little more uniform, while in 10% of the varieties no difference in uniformity was seen.




From literature and our own findings it appears that the growth of a male or female plant from seed, except for the predisposition in the gender chromosomes, also depends on various environmental factors.
The environmental factors that influence gender are:

• a higher nitrogen concentration will give more females
• a higher potassium concentration will give more males
• a higher humidity will give more females
• a lower temperature will give more females
• more blue light will give more females
• fewer hours of light will give more females

feminized seeds are achieved over sevral generations . the more generations the more female seeds. you cant on the first generation give the plant silver solidium solution and expect the seeds to be 100 percent female .hope this helps.
