Problems solved by technology

[0005] In order to change this status quo, our field began to select and breed new pea varieties in 1998; after 20 years of observation and research, meticulous cultivation, experimentation, demonstration and research, we have now selected and bred new pea varieties that meet the breeding objectives. There is no research report on this aspect at home and abroad.

Embodiment 1

[0015] Hybrid combination: {[(Ma pea x white jade tendril pea) F 2 + Radiation] F 2 ×American coniferous peas}F 1 ×{[(Beijing No. 5 × Donave) F 2 + Radiation] F 2 × Zhongwan No. 5} F 1

[0016] 1. Test output

[0017] From 1998 to 2007, a total of 33 strain identification, strain comparison, and production comparison experiments were conducted in Wuwei City. The average yield per mu was 405.6 kg, which was 77.0 kg higher than that of the control pea pea 328.6 kg, an increase of 23.4%. See Schedule 1

Abstract

The invention discloses a Pea seed selection method, relates to a plant heterosis utilization method, and belongs to the technical field of the agriculture. The method is characterized in that the composition is {[(spotted colored pea*white jade tendril pea)F2+radiation]F2*American needle-leaf pea}F1*{[(Beijing No.5*Donough)F2+radiation]F2*Zhongwan No.5}F1. According to the invention, Guwan No.1 is half-leafless pea, and a strong lodging-resistant population can be formed through the mutual winding and drawing of the developed tendrils in plants; the concentrated florescence and the fast maturation yellowing create conditions for the irrigated land crop rotation, so it is benefit for drug spray for disease and pest control; pinnately compound leaves protrude to form the tendrils, so the ventilation and light transmission condition in the field populations are good, thereby it is benefit for the drug spray in the growth stage for the disease and pest control, and the mechanical operation is suitable; and good grain quality, good disease resistance, good comprehensive agronomic properties, large yield increase potential, strong lodging resistance, and suitableness for irrigated land plantation are reached.

Description

technical field [0001] The invention relates to a method for utilizing plant heterosis, which belongs to the field of agricultural technology, in particular to a pea breeding method. Background technique [0002] Pea is a leguminous plant, the scientific name is Pisum sativum Linn , because of its strong adaptability, it has a wide geographical distribution all over the world. Peas have been cultivated in my country for more than 2,000 years, and are now cultivated in many countries in the world. The young leaves of pea pods and bean sprouts are rich in vitamin C and enzymes that can decompose nitrosamines in the body, which can decompose nitrosamines and have anti-cancer and anti-cancer effects. Peas are different from ordinary vegetables. They contain substances such as bifurcated acid, gibberellin and phytolectin, which have the functions of antibacterial, anti-inflammatory and enhancing metabolism; peas and bean sprouts are rich in dietary fiber, which can prevent con...
