Three common varieties of four-rowed beans

1. Precocious Yidou 833

A new precocious strain bred by South China Institute of Botany, Chinese Academy of Sciences, which is a precocious variant line of four-rowed bean variety "H45jinl", was introduced from Australia. The economic character is good, the maturity period is early, the range of adaptation is wide, the flowering stage is earlier, the flowering stage is 63 days earlier than that of the parents, and the maturity period is also earlier. The vine is 6 meters long, with alternate leaves, broadly ovate to broadly rhomboid. Stem, Dt green, plant height of 30 cm where the main stem leaves bear. Inflorescences. Racemes. Corolla blue. The pod is four-angled, tender English-green. The ripe English is dark brown. Seeds suborbicular, navel slightly raised. Seed coat beige. The length of English is 16m / m / 27m. There are 8 seeds in total, the weight of single seed is 2.8mi 3.2g, and the weight of 100 seeds is 31g. The roots near the ground can grow into tubers. This variety has the characteristics of strong nitrogen fixation ability, resistance to virus disease, low effective accumulated temperature, insensitive to light and so on.

2. Guifeng No. 1

Some very early-maturing varieties were selected from the four-rowed bean line "K Ms-12" introduced from abroad by Guangxi Agricultural University. There are 6 lateral vines nailed to the left of 3 meters of main vine. It is suitable for close planting, with 400u-6000 plants per 667 square meters. The bean milk is flat and fleshy. It is not easy for fiber to age. Dou Douying talks about green. The average number of seeds per English is 9; mature seeds are dark gray. A hundred seeds are 26 grams. At first, the node instrument of inflorescence was 1 Mel 6 nodes.

3. Gui Dai

The natural mutant "K Ms-101" bred by Guangxi Agricultural University from the trailing four-rowed bean line "K Mel 8" is a dwarf variety with good economic characters and no need to set up cultivation. Gui'ai is a limited growing variety with white cap. The plant is clumpy with strong dividing ability. After the main vine grows 11-13 true leaves, its bud differentiates into flower bud and caps itself. The length of the main vine is about 80 cm, but the first to ninth nodes of the main vine are short. it only accounts for about 1 of the length of the main vine. After the seed vine grew into 6 leaves, the terminal bud differentiated into flower bud and capped itself. The axillary buds of the stem nodes of the main vine, son vine and sun vine can differentiate into flower buds and bloom. The flowers are axillary racemes with 8 florets per inflorescence, and the Corolla is purple. Dou Ying green with yellow, 18 cm long, Douying cross section is square, single plant knot number is about 45 inches. Ripe beans are dark brown. Testa yellowish brown to brown. The root system is well developed. the whisker root can produce a large number of nodules. the root system can expand into a hypertrophic root tuber. It can produce more than 1100 grams of tender pods and 247kg of mature seeds per 667m2. The root is about 95 kg.

2. Seedling raising method of four-rowed bean

Most of the four-rowed beans are propagated by seeds, and stem cuttings and roots can be used as propagation materials; seedlings are raised in hotbeds or nutrient bowls in the Yangtze River basin from the end of March to the beginning of April, and can be transplanted and planted in the first and middle of April.

Well, that's all for what the editor wants to share with you today. I don't know if you like to eat four-rowed beans. Anyway, the editor still loves to eat, and the three common varieties mentioned above still taste good. If you also plan to plant them, you can learn the breeding methods above.
