Selection and Breeding of Drought Resistant,Water-saving and High-yield Wheat Variety Cangmai 028

Cangmai 028 was selected and bred according to the climatic characteristic of the winter wheat in Heilonggang Basin taking 98(083)as the female parent and the Canghe 030 as the male parent by "two-row parallel alternate selection" method.Cangmai 028 has characteristics of high resistance,water-saving,high and stable yield,and rich genetic background.This study elaborated selection and breeding background and methods,characteristics,quality,and yield of Cangmai 028.

Breeding and High-yield Cultivation Technology of Wuqing No.1, a New Cultivar of Black Soybeans

The research introduced selection and breeding process, characteristics and high-yield cultivation technology of Wuqing No.l. Wuqing No.l, also named Gaoyou black soybean, is bred based on Danbo black soybean introduced from Japan in 1996 by Gaoyou Vegetable Cultivation Technology Station and Yangzhou Agricultural Technology Promotion Station. It was named in 2014 by Jinagsu Crop Cultivar Approvement Committee. The cultivar is high-yielding with high quality, big seeds, high resistance to stress, as well as high health-care value.

Conservation and breeding for Hequ Tibet Mastiff in China

This paper gave the standards to evaluate Hequ Tibetan Mastiff on body type, appearance, body measures and temperament. A nucleus group of breeding consisted of high-grade individual according this standards, and it was for enhancing the proceeding of selecting and breeding of Hequ Tibetan Mastiff. By this way, after working on three generations it had been gained that effective population size of the nucleus group of breeding was 96, increasing numbers of inbreeding coefficient was 0.005, male and female body height were 72.1 cm and 70.2 cm, their cannon circumference were 16.3 cm and 15.2 cm, respectively.

Thinking on Breeding of Fecundity Genes in Guizhou Black Goats Through Cost-benefit Analysis of Mutton Sheep by SAS Multivariate Stepwise Regression

The total output value of mutton in Northwestern China has accounted for more than 60%of the total output value of animal husbandry over the years.It can be seen that the mutton industry in Northwest China not only plays a pivotal role in animal husbandry,but also plays an important role in Chinese agriculture.In this study,based on cost accounting theory,income-related theories and total factor productivity theory,using basic knowledge of statistics and economics,drawing on existing research results at home and abroad,and adopting a combination of qualitative analysis and quantitative analysis of SAS multiple stepwise regression,the changing trends of cost-benefit of mutton sheep breeding in Northwest agricultural and pastoral areas and influencing factors of production costs and production efficiency were investigated,aiming to provide reference for saving mutton sheep feeding material resources,reducing mutton sheep breeding costs,and improving mutton sheep breeding benefits.
