Abstract

The present study was conducted to compare the genetic variability parameters among selfed lines of population A (PDM 53 x PDM 4441) and population B (HKI 1105 x HKI 323) and also random mated population A (PDM 53 x PDM 4441) and random mated population B (HKI 1105 x HKI 323) using original inbred parents and three commercial checks, HM-4 (National check), CPB 468 and TENDER (Private check). High heritability coupled with high genetic advance was observed for number of cobs per plant, husked cob weight, dehusked cob weight, baby corn yield with and without husk per plant among selfed populations and a similar trend was observed in random mated populations except for ear length and days to 50 % silking. In total the variability observed was more in random mated populations than selfed lines because allelic frequency differences occur in random mated populations and the pool of gametes originating from male and female is different when compared to the pollen source in selfed populations. The frequency of transgressive segregants were more in random mated Population A (PDM 53 x PDM 4441) and the most promising transgressive segregant identified can be used in the further breeding programmes.

自交系与随机配种群体A (PDM 53 × PDM 4441)和群体B (HKI 1105 × HKI 323)遗传参数的比较及越界分离的鉴定
本研究利用原始近交系亲本和HM-4(国家检查)、cpb468和TENDER(私人检查)三种商业检查,比较了种群A (PDM 53 × PDM 4441)和种群B (HKI 1105 × HKI 323)的自交系遗传变异参数,以及随机交配种群A (PDM 53 × PDM 4441)和随机交配种群B (HKI 1105 × HKI 323)。在自交系群体中,单株穗轴数、去壳穗轴重、去壳穗轴重、单株带壳和不带壳玉米产量均具有较高的遗传力和遗传进步;在随机交配群体中,除穗长和出丝天数达到50%外,均有类似的趋势。总的来说,在随机交配群体中观察到的变异比自交系中观察到的变异更大,这是因为随机交配群体中等位基因频率存在差异,并且与自交系中来自雄性和雌性的配子池不同。在随机交配种群A (PDM 53 x PDM 4441)中,越界分离的频率更高,所鉴定的最有希望的越界分离可用于进一步的育种计划。
