step 3.1 Phenotype
I built-up phenotypic investigation about Vida/MTHW0202 RIL society and you will moms and dads adult into the around three rainfed as well as 2 irrigated environment in 2013?2014 increasing 12 months. Dining table step one records setting grouped towards the mutual, rainfed, and you can irrigated surroundings for a couple faculties which were obtained regarding the moms and dads and you can RIL populace. The brand new rainfed grains yield RIL indicate are 35% below the fresh irrigated RIL grain yield imply. Simultaneously, rainfed give component traits take to lbs, thousand-kernel lbs, and you can seeds matter per direct was 4, seven, and you will eight% below the brand new irrigated environment, respectively. Alternatively, active tiller number give component RIL imply is https://datingranking.net/local-hookup/washington/ 8% high regarding the rainfed surroundings than the irrigated environments.
- Note. GLDAH, green leaf years just after supposed, a description of your own remain-environmentally friendly characteristic.
- * Factor among RIL moms and dads and you may RIL entries during the .05 chances level.
- ** Factor one of RIL moms and dads and you will RIL records from the .01 chances top.
- *** Significant difference certainly one of RIL mothers and you can RIL records during the .001 possibilities level.
Grain yield among parents was significantly different (P < .05) in only the rain-fed environments where Vida's grain yield was 6.0% higher than MTHW0202. MTHW0202 had significantly higher (P < .05) seed diameter and seed number per head across, rainfed, irrigated, and combined environments. Vida had significantly higher productive tiller number (P < .01) vs. MTHW0202 in all environments. Vida also had significantly later heading date (P < .001) and maturity date (P < .05) vs. MTHW020 across combined, rainfed, and irrigated environments, but GLDAH was not significantly different among parents in any environment. Thousand-kernel weight was significantly higher (P < .01) in MTHW0202 vs. Vida in the combined and irrigated environments. Vida was significantly taller (P < .05) than MTHW0202 in the combined and rainfed environments.
Significant differences among RIL entry means were also observedbined environment RIL entry means were significantly different for test weight (P < .001), thousand-kernel weight (P < .001), seed diameter (P < .001), seed number per head (P < .001), heading date (P < .001), GLDAH (P < .05), maturity (P < .05), plant height (P < .001), and grain protein content (P < .001) (Table 1). Significant differences among RIL entry means were also observed for thousand-kernel weight (P < .001), seed number per head (P < .001), plant height (P < .001), and grain protein content (P < .001) in rainfed environments. Plant height RIL entry means were significantly different (P < .001) in the irrigated environments. Transgressive segregation was observed in the RIL population for all traits in the combined, rainfed, and irrigated environments, except for GLDAH in the irrigated environments and maturity in the rainfed environments.
3.2 Correlation data
Pearson correlations between traits varied among environments. In the rainfed environments, GLDAH was positively correlated with yield (P < .001, r = .37), test weight (P < .001, r = .47), and thousand-kernel weight (P < .001, r = .38), but was negatively correlated with seed number per head (P < .05, r = ?.20) and heading date (P < .001, r = ?.36) (Table 2). In irrigated environments, GLDAH was positively correlated with test weight (P < .01, r = .25) and thousand-kernel weight (P < .01, r = .24), but was not significantly correlated with yield (Table 2). Seed number per head (P < .05, r = ?.20) and heading date (P < .001, r = ?.39) were negatively correlated with GLDAH in irrigated environments (Table 2). Yield was positively correlated with test weight (P < .001, r = .36) and thousand-kernel weight (P < .01, r = .24), but was negatively correlated with heading date (P < .001, r = ?.31) in rainfed environments (Table 3). Yield was positively correlated with seed number per head (P < .001, r = .33), heading date (P < .05, r = .19), and productive tiller number (P < .001, r = .29), but was not significantly correlated with test weight and thousand-kernel weight in irrigated environments (Table 3).
