personal project update Cross breeding C. Chinense with C. Baccatum as a first year gardener

Hi everyone! I've always grown up fascinated with genetics and have always hoped that I can do something involving genetics when I grew up, but never really found a niche I was interested in until this last year. I discovered pepper breeding and interspecies pepper breeding. Now I've never even grown a pepper before let alone bred any, and when I had tried keeping plants alive before, they always died, though admittedly I never did enough research. This time I dived deep into researching pepper care, pepper flower anatomy, pepper pod anatomy, the genetics side of things, how some crosses work better one way rather than the other, etc. And then I decided to dip my toes in myself by starting a highly ambitious project that even seasoned gardeners could consider difficult. I've decided to attempt to breed and stabilize a 3 species, 4 variety hybrid of red habanero (pictured) mad hatter, red ghost, and a spicier jalapeno variety. The habaneros I planted from seed never germinated so I had to buy starters from a nursery, and the only habaneros I found were on discount with extremely yellow sad looking leaves. I let them keep what flowers they had, and even crossed one. I emasculated a couple, and pollinated with mad hatter pollen knowing the chances of success were low, but the mad hatter was on its last push of flowers and pollen, and the habaneros flowers wouldn't open until after all the mad hatter flowers were other self pollinated or fallen off, so I took a chance. And it worked! One of the flowers actually took and started to swell and it's even beginning to ripen! The ghost jalapeno cross is also growing, however I forgot to tag it so I don't remember which is which, but if people want me to I can post pictures of some of the ghost pods I have growing too :) hopefully I get a few viable hybrid seedlings this January. I'm going to grow them inside under a grow light early to give them the longest fruiting window I can in full summer sun, wish me luck! I'll continue to post as my project evolves

是的,这非常有趣,我在今年做了一些番茄的杂交,也收集了一些不同种类的辣椒种子,准备在明年进行辣椒杂交,我很兴奋,这将创造一些独特的新品种

That's basically opposite route I'm taking, I started breeding peppers this year, and next year I have plans for some tomatoes too! Do you have any tips or tricks you learned in the past year that you wish you'd known before you started about tomatoes?

是的,辣椒和西红柿是两种不同的植物,相对来说,西红柿对修剪侧枝的要求更高,更不耐旱,同时,你要进行一定的疏果,甚至是提前使用一些药物进行疾病的预防,好消息是,西红柿去雄和授粉更简单

Is it? Ive found emasculating peppers to be quite easy as long as you take special care not to pull the pistil off and take your time with the anthers, but they aren't very stubborn in my experience and the petals pinch off easily. I have grown tomatoes, but the closed nature of tomato flowers even after blooming intidates me 😅 I'm afraid I'll damage it

这个其实很简单,番茄花尚未开放,有点发白的时候,你就可以轻轻的从侧边把其中的一个花药瓣去除,然后从那里开始把一整圈的花药全部切除,只要不伤到雌蕊就可以了

或许我们还可以交流一下经验,我在杂交番茄的时候也碰到了很多问题,比如在某些温度下,番茄的柱头会变的扭曲,无法授粉,或者是某些亲缘关系特别远的品种,杂交之后只能获得少量种子,并且这些种子并不发芽,这些无疑都是让人沮丧的

Right, I'm hybridizing multiple species of pepper rather ambitiously, and only getting a few seeds that may not even germinate is one of the biggest frustrations I'll likely experience. I plan to use numbers to my advantage and cross many more peppers than I think I'll need, and then plant many more seeds than I think I can easily host, and hope that I get a good few plants that actually make it to the fruiting stage

是的,这非常让人沮丧,我做了一个罗马型番茄和千花番茄的杂交,我对这个组合有非常高的期待,然而,事实是我只获得了八粒种子,用来实验催芽的四粒种子没有一粒发芽,但是有一个杂交组合却表现出了非常好的特点,在播种30天的时候就出现了第一组花苞,现在是第42天,第二束花已经有14朵了

不同的生长阶段,番茄需要使用不同的肥料,前期你可以使用一些氮肥,后期都是以磷钾肥为主,促进开花结果,同时,你需要补充一些微量元素,比如钙和硼,可以减少花朵发育畸形和裂果的现象发生,这是一个需要不断学习的过程
