Embodiment 1

[0021] American lentil HET1, a foreign excellent variety resource, has the biological characteristics of bean borer resistance, red color, pod length 4cm, thickness 3mm, 16 hours of long sunshine, and high temperature resistance of 35 degrees. Domestic excellent variety resource Nanhui local flat-1 has the biological characteristics of bean Borer, green, pod length 12cm, thickness 6mm, 8 hours of short sunshine, biological characteristics of resistance to low temperature of 15 degrees. The HET1×Nanhui long-pod local flat hybrid, the first generation of the hybrid showed the biological characteristics of bean borer resistance, red color, pod length 10cm, thickness 6mm, 11 hours of medium sunshine, resistance to low temperature of 15 degrees and high temperature of 35 degrees, this kind of The first generation of hybrids with heterosis has better yield and stability. It has the effect of increasing the yield of lentils by 15%. And make the growth potential and resistance of the...

Embodiment 2

[0023] American lentil pET1, an excellent foreign variety resource, has the biological characteristics of bean borer resistance, white pod length, 6cm pod length, 5mm thickness, 14-hour long sunshine, and high temperature resistance of 40 degrees. Borer, red, pod length 10cm, thickness 8mm, 10 hours of short sunshine, biological characteristics of resistance to low temperature of 10 degrees. HET1×Nanhui long pods were crossed locally, the first generation of hybrids showed the biological characteristics of bean borer resistance, red color, pod length 12cm, thickness 8mm, 12 hours of medium sunshine, resistance to low temperature of 10 degrees and high temperature of 40 degrees. The first generation of hybrids with heterosis has better yield and stability. It has the effect of increasing the yield of lentils by 20%. And make the growth potential and resistance of the first generation of hybrids stronger.

Embodiment 3

[0025] American lentil pET5, a foreign excellent variety resource, has the biological characteristics of bean borer resistance, white pod length, 5cm pod length, 4mm thickness, 15 hours of long sunshine, and high temperature resistance of 37 degrees. Borer, red, pod length 11cm, thickness 7mm, 9 hours of short sunshine, biological characteristics of resistance to low temperature of 13 degrees. HET1×Nanhui Native Bian-2 was crossed. The first generation of the hybrid showed the biological characteristics of bean borer resistance, red color, pod length 11cm, thickness 7mm, 13 hours of medium sunshine, resistance to low temperature of 13 degrees and high temperature of 37 degrees. The first generation of hybrids with heterosis has better yield and stability. It has the effect of increasing the yield of lentils by 25%. And make the growth potential and resistance of the first generation of hybrids stronger.

[0026] The method of utilizing the heterosis of the first generation o...

Abstract

The hybridizing combination process of utilizing heterosis of haricot includes the following six aspects: selectively breeding with long sunshine excellent haricot parent and short sunshine excellent haricot parent; selectively breeding with high temperature resisting excellent haricot parent and low temperature resisting excellent haricot parent; selectively breeding with excellent haricot parent of proper pod size and thickness; selectively breeding with excellent haricot parent of good pod color; selectively breeding with excellent haricot parent of high disease resistance; and selectively breeding with excellent haricot parent of proper genetic relationship. The present invention can obtain maximum heterosis of the polymerization bred F1 generation haricot hybrid and can raise greatly the yield, quality, disease resistance, etc. of haricot.

Description

technical field [0001] The invention relates to a method for hybridization of lentils, in particular to a method for hybridization using heterosis of lentils, which is used in the field of plant genetics and breeding. Background technique [0002] Lentils are a local characteristic vegetable variety in Shanghai, with a production area of ​​10,000 mu, which is unprecedented in the world. At present, there is a huge demand for lentils in domestic and foreign markets. The use of heterosis in crop breeding at home and abroad has been very successful, and remarkable results have been achieved in crops such as corn, rice, and cotton. [0003] After searching the existing technical documents, it was found that Sun Huan proposed in the article "Research Progress on the Utilization of Soybean Heterosis" (Chinese Journal of Oil Crops, Volume 25, Phase 2, Page 92-100, March 2003), and proposed that hybrids in soybeans are currently Like other crops, "three lines" are mainly used in t...
