immature oocytes become self-sterile spontaneously by 3 h after germinal vesicle breakdown in vivo as well as in vitro, we allowed animals one week to accumulate mature gametes, followed by natural spawning instead of dissection to avoid contamination of immature oocytes.

Beit Alpha MR' (OP) 52 to 65 days to flowers, which do not 'Cool Breeze' (F1) maturity require pollination by 'Diva' (F1) insects.
The segregation rate of the three seed colors in LBGMF lines was determined by counting the percentage of white and blue seeds in all seeds from 20 self-fertilized plants sampled from the plot, then counting the percentage of self-fertile
plants that were homozygous for deep blue grains in all blue grain plants of the LBGMF plot, and finally calculating the segregation rate of the three seed colors in self-fertile
Adeniums, however, are not self-fertile
, and cross-pollination between plants is required if they are to produce seed.
Although it's self-fertile
and so can be grown alone, 'Sharpblue' does better when cross-pollinated with other southern highbush varieties such as 'Sunshineblue'.

Temptation' is a recently introduced self-fertile
cultivar of this popular shrub.
Most gardens should be able to accommodate one apple tree, ideally two because no apple is completely self-fertile
Walnuts may not be the easiest things to grow in our climate - and indeed, the walnut tree originates from Persia - but new self-fertile

plants will grow in most soils and can yield up to 4.
While cherry trees were massive and would have taken over the garden, today you can buy self-fertile
smaller varieties - some of which only grow to around 1.
Many newer varieties such as Scrumptious are self-fertile
and will produce apples with only one tree.
