摘要

在2018-19和2019-20冬季连续2年，采用随机完全区组设计，3个重复对26个基因型中晚期和晚期组的实验材料进行评价。记录了每公顷商品凝乳产量及其17个相关性状的数据。在产量和组成性状上观察到充分的遗传变异。不同基因型的平均值显示，在可销售凝乳产量及其贡献性状方面的性能差异很大。这表明菜花基因型之间存在着巨大的遗传多样性，这将为菜花的遗传改良提供巨大的机会。平均性能评价显示，DPCa CMS 1在可销售凝乳产量方面比标准检查Palam Uphar高出27%，其次是DPCaf W3、DPCaf US和DPCaf 30，这主要是由于凝乳深度、凝乳直径、叶片长度、叶片宽度、最佳植株框架、凝乳密实度/结实度、植物毛重和净重的显著贡献。

Mean performance studies in mid late and late group of cauliflower (Brassica oleracea L. var. botrytis)

The experimental material comprising of 26 genotypes belonging to mid late and late group was evaluated in randomized complete block design with three replications for two consecutive years during winter season of 2018-19 and 2019-20. Data were recorded on marketable curd yield per hectare and its 17 related traits. Sufficient genetic variability was observed for yield and component traits. The perusal of mean values of different genotypes showed wide variation in the performance with respect to marketable curd yield and its contributing traits. This indicates great extent of genetic diversity among genotypes which would provide immense opportunities for genetic improvement of cauliflower. The evaluation of mean performance revealed that DPCa CMS 1 showed advantage of 27% for marketable curd yield over standard check Palam Uphar followed by DPCaf W3, DPCaf US and DPCaf 30 which was mainly due to significant contribution of curd depth, curd diameter, leaf length, leaf width, optimum plant frame, curd compactness/solidity, gross and net plant weight.
