tailieunhanh - Triple test cross for yield and quantitative components in Brinjal (Solanum melongena L.)

In the present study, the components of genetic variation were studied in AN (Arka Nidhi) and SN (Singh Nath) for quantitative characters. The estimates of both additive and dominance components were significant for all the characters except days to 50 per cent flowering, fruit diameter, number of branches per plant and pedicel length. Epistasis (i) and (j+l) type was significant in all the traits except except fruit diameter (cm). | 2017 6 5 903-911 International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 6 Number 5 2017 pp. 903-911 Journal homepage http Original Research Article https Triple Test Cross for Yield and Quantitative Components in Brinjal Solanum melongena L.

Chandel and Aachal Chauhan Department of Vegetable Science and Floriculture CSK HPKV Palampur Himachal Pradesh 176 062 India Corresponding author ABSTRACT The success of vegetable breeding operations mainly depends upon the nature and extent Keywords of genetic components of variation. Thus it is imperative to have reliable estimates of such Triple test cross components in order to formulate an efficient breeding strategy. In the present study the additive components of genetic variation were studied in AN Arka Nidhi and SN Singh Nath for dominance quantitative characters. The estimates of both additive and dominance components were epistasis. significant for all the characters except days to 50 per cent flowering fruit diameter number of branches per plant and pedicel length. Epistasis i and j l type was significant in all the traits except except fruit diameter cm .

Introduction Brinjal is a well known vegetable crop and it effects Mackay 2014 . In fact a good genetic is generally grown in the tropical sub tropical model enables the breeder to have precise and warm temperate area of the world. It is a and unbiased estimates of all the components good
