let me start by saying yellow pear......... suck. they have no real super flavour. they are just as describe, a yellow, pear shaped tomato. they flavour is quite, bland. so, if you are looking for a super, sweet tasting tomato, you aren't going to get it. it has more a mild, acid flavour.
but, when it comes to suckers, you have to know your growing season. those in northern regions should pinch the suckers on indeterminate varieties, this is due to your very short growing season. don't touch determinate, like patio. yellow pear is a indeterminate but if your season is short, pinch. if your season is long, you can snake the plant through your garden, pinching at the sucker, whilst burying the post-sucker and it will root even further. determinate will not.
i have grown yellow pear in the past and do not save the seed, just based on the fact that the plant is so readily available in the spring. now, you also have to watch if your yellow pear is an heirloom or a hybrid, the plants i grew, were hybrids. they produced a lot of fruit but with little flavour that i was looking for. i did many side by side comparisons, with the ultimate judge....my wife, who only buys tomatoes from the grocery store and detests anything from the garden. even she couldn't detect the difference in the hybrid yellow pear from those similar purchased in the supermarket. in comparison with other heirlooms that i grew, that had a noticable flavour, she could detect the difference without coaching.
as, i look around my basement, i have heirloom tomatoes everywhere, growing large and lanky due to the cold and lack of sunlight. for a while i was driving around with my tomatoes in the back of my van, but the recent turn in weather, back below zero, has made me bring the plants back in the house - looks like next week i can go back to the van.......... peppers are completely house bound!
