Description
Technical field
The invention belongs to the peanut breeding technical field, specifically be meant a kind of selection of super-high yield peanut kind.
Background technology
Peanut is the main oil crop of China, and SOYBEAN IN HIGH-YIELD BREEDING is the main target of peanut breeding always, is the peanut breeding Eternal Theme.Because the peanut varieties improvement reaches more than 30% the contribution rate of per unit area yield and gross output, so the seed selection of peanut varieties is all paid much attention to, the input of increasing funds in countries in the world.During the State's Ninth Five-Year Plan period, China has selected the peanut varieties of some high-yield disease resistings, and important function has been played in the raising of the peanut yield of China, but these kind amounts of increase in production little (most of product kind is shown no increases in output or increased production about 5%).Press for the super-high yield peanut kind that on output, has real breakthrough on producing at present.
At present result of study thinks that high-yield peanut variety blooms concentratedly, and the flower amount concentrates on the early stage of blooming, and effectively spends rate, becomes pin rate, setting ratio, plumpness height.(Zhuan Mingchuan, 2003).Under the certain situation of strain number, peanut yield and its main composition factor (the full fruit of individual plant number, heavy, the milled rice rate of all kinds of fruits) are extremely significant positive correlation, and three factors are main restricting factors (Zhang Baoliang, 2003) that peanut yield changes.The dragon of promoting mainly the early maturity culture of intermediate variety average specific the present age gives birth to type kind high yield 38%.The reason that output improves mainly is owing to improved economic coefficient, the raising of biological yield also play an important role (Wan Yongshan, 1999).The main path of the further high yield of peanut is a high yielding variety of selecting for use characters with plant good; Improve utility rate of luminous energy and promote the photosynthetic product reasonable distribution; Rely on main solid branch to realize the many fruits of colony fruit full (Sun Yanhao, 1998).Per plant number, plant height, all kinds of fruits heavily reach half kilogram of fruit number and output be proportionate (Dong Wenzhao, 1999).The degree of association sequence of the yield component of peanut is followed successively by: hundred benevolence weight＞all kinds of fruits weight＞per plant number＞fruit bearing shoot number＞kernel percents＞side shoot length＞total branch amount＞plant height (Chen Hua, 2007).Prolonging crop growth period, improve the plant photosynthetic efficiency and increase the allocation proportion of photosynthetic product to gonophore, is the effective way (Zheng Yaping, 2002) of peanut varieties improvement.More than 10%, middle grain type increases production (in big waves, 2003) more than 15% than main breed to the big grain of super high-yielding breeding target type than kind volume increase of the same type.In fact, the peanut high yield is not to rely on single mechanism, but number of mechanisms plays a role jointly, just in different kinds, and the leading position difference that different mechanisms is shared.The peanut varieties of breeding at present is partial to single index choice, because peanut yield is by controlled by multiple genes, breeding in a short time in output has the kind of breakthrough to be difficult to realize.
