PRODUCTION OF CULTIVARS WITH YELLOWISH FLOWER IN PELARGONIUM.

采用花瓣培养和种间杂交的方法，获得天竺葵淡黄色花色。一些淡黄色花的树种被用来进行花瓣培养。在附加2.5 mg/L NAA、2.5 mg/L激动素的白色培养基上，所有品种均能观察到愈伤组织的形成。而在附加不同浓度的生长调节剂(NAA、激动素和TDZ)和天然有机物质(卡扎氨基酸、蛋白胨和三丁酮)的3种基本培养基上，不定芽和生根的频率都很低。从50多个杂交组合中获得了许多F1植株。以白杨(Hoare组)ב柠檬’组(天竺葵组)杂交，通过胚珠培养技术获得了几株F_1植株。目前，F1混合动力车正在温室里生长。当植株成熟开花时，我们将选择我们尊重的花朵，并为F_2杂交种，F_5代继续进行这一研究。

PETAL CULTURE AND INTERSPECIFIC HYBRIDIZATION WERE CARRIED OUT TO PRODUCE OF YELLOWISH FOWER COLOR IN PELARGONIUM. SOME SPECIES WITH YELLOWISH FLOWER WERE USED FOR PETAL CULTURE IN SECTION HOAREA. CALLI FORMATION WERE OBSERVED IN ALL SPECIES ON THE WHITE MEDIUM SUPPLIMENTED WITH 2.5 MG/L NAA, 2.5 MG/L KINETIN. WHILE THE FREQUENCY OF SHOOT AND ROOT FORMATION WAS LOW ON EVERY DIFFERENT MEDIUM WHICH ARE 3 BASIC MEDIUM SUPPLIMENTED WITH THE VARIOUS CONCENTRATION COMBINATION OF GROWTH REGULATORS (NAA, KINETIN AND TDZ) AND NATURAL ORGANIC MATTERS (CAZAMINO ACIDS, PEPTONE AND TRYPTONE ).CROSSING COMBINATION IN TWO CULTIVARS IN SECTION HOAREA, AND BETWEEN SECTION HOAREA AND SECTION PELARGONIUM FOR THE IMPROVEMENT OF YELLOWISH FLOWER IN F_1 HYBRIDS, FROM MORE OVER 50 CROSSING COMBINATION MANY F1 PLANTS WERE OBTAINED. FROM THE CROSS P. RAPACEUM (SECTION HOARE) X P. CRISPUM 'LEMON CRISPUM' (SECTION PELARGONIUM) A FEW F_1 PLANTS WERE PRODUCED THROUGH OVULE CULTURE TECHNIQUE. IN THE PRESENT F1 HYBRIDS ARE GROWING IN THE GREEN HOUSE. AT THE TIME THE PLANTS BECOME MATURE AND FLOWERING WE WILL SELECTED FLOWERS THAT WE RESPECTED AND CONTINUES THIS STUDY AGAIN FOR F_2 HYBRIDS, F_5 GENERATION.
