Green beans germination rates

In my personal experience the next bush beans germination rates are as follow..

The stringless green pod was sowed in July plain summer(high 90's daytime almost 100). Although it had great germination rate, the heat seemed not to help in the development of juice beans, they were basically like jerky beef in appearance and I never used soil inoculant.

On blue-lake I had better result, those were sowed in the very last 2 weeks of summer so at the time they were little plants the heat already resided and produced good healthy bean pods, again no inoculant were used here and the difference between the previous  string-less bean and blue-lake harvest was abysmal.

Burpee's stringless green pod. Excellent 85% to 90%
Blue lake 274. Excellent 90%

This 5 beans were sowed in day time temperatures of 60's to mid-high 70's and rare low 40's to 50's and 60's at nigh time. During this time only a splash of water rained. The sowing date was march 1st, the results here are 10 days later. I used soil inoculant

Royal burgundy. Excellent. 90% to 95%
Golden wax improved. Medium or 50%
Dragon tongue. Excellent 90% to 95%
Kitchen king. Poor 50%
Tenderpick. Worst 10%

The seeds that didn't germinate after 2 weeks on the worsts performance of all above are going to be resowed by new seeds and I'll see if the rates improve. I'll keep updating...

(Update).

Tenderpick definitely useless, the 2nd sowing gave only 2 or 3 germinations from 8 seeds, I'll never sow it again.

Kitchen king is only king in the name because the plants wilt or at least they seem weaker than the other ones, but until the harvest is ready I'll comment about the taste. I'll keep updating.

For the 5 beans above, here are the harvest results.
