摘要

以MTU1010和BR2655为来源的190个水稻重组自交系(RILs)为材料,进行了遗传变异研究。2016年收获期,植株高度和单株有效分蘖数记录了较高的PCV和GCV,而2016- 2017年收获期,每穗实粒数、单株产量、籽粒锌浓度和籽粒铁浓度记录了较高的PCV和GCV。所有性状的PCV估计值均略高于相应的GCV估计值,表明这些性状受环境影响最小。在2016年和2016-17年收获季,在株高、多产分蘖数、每穗实粒数、千粒重、单株产量、籽粒铁浓度和籽粒锌浓度等性状上分别观察到高遗传力和高遗传推进率,表明这些性状受到加性遗传控制,简单的选择可能有效地朝着理想的方向进一步改进这些性状。铁、锌浓度较高的ril J16、J144和J146单株产量较高。

Genetic studies for yield and nutritional traits in unpolished rice RILs of MTU1010 x BR2655
A study was carried out to access the genetic variability in a set of 190 recombinant inbred lines (RILs) of rice derived from MTU1010 and BR2655. Plant height and number of productive tillers per plant recorded high PCV and GCV during kharif 2016, whereas number of filled grains per panicle, grain yield per plant, grain zinc concentration and grain iron concentration during rabi 2016-17.The estimates of PCV were slightly higher than the corresponding GCV estimates for all the traits studied indicating that the characters were least influenced by the environment. High heritability coupled with high genetic advance as per cent of mean was noticed for traits like plant height, number of productive tillers, number of filled grains per panicle, 1000-grain weight, grain yield per plant, grain iron concentration and grain zinc concentration respectively during kharif 2016 and rabi 2016-17 indicating that traits are under additive genetic control, simple selection would likely be effective for further improvement of these traits in desirable direction. RILs J16, J144 and J146 have shown higher grain yield per plant with high iron and zinc concentrations.
